SIX SIGNS YOU MAY HAVE GPC

FROM YOUR CONTACT LENSES

• Itchy eyes as contact lenses get older

• Lenses that slide and stick under the upper eye lid

• Irritation Every Time You Blink

• Mucous Discharge and Foggy Vision
  

• Lenses That Discolor and Develop a Film
  

• Intermittent Red Eye With Feeling Something is Scratching Your Eye
  

In the early years of soft contact lenses there was one choice, the Bausch & Lomb Soft Lens. The cost of a single pair of these miraculous new soft, comfortable lenses was between $300 and $400 when first introduced in 1971. Accounting for inflation, today that would be almost $2000. There was a very strong financial incentive to make the lenses last as long as possible. Using enzyme cleaners and sending lenses off for a special factory cleaning were common procedures. Lenses were often used for 3 to 4 years until they were yellowed and covered with numerous deposits from components of the tear film. Lipid bumps, calcium and mineral deposits, protein deposits and frequent tears and little missing chunks of the lens edges were tolerated well past the healthy tolerance of the eyes.

A new eye problem begin to show up in a number of the wearers of these new soft contact lenses. As lens technology progressed and prices came down lenses were replaced more frequently and the mystery red eye syndrome seemed to drop off. Then in 1981 the Hydrocurve soft contact lenses was introduced as the first contact lens for over night wear, the advent of extended wear contact lenses.  Cases of this new eye problem started to show up again and become common enough to recognize and diagnose.

The typical patient would come in to see the optometrist complaining about eyes that were red and irritated, possibly itching, and contact lenses that would slide around on the eye, sometimes falling out with blinking. On further questioning the lenses usually were sliding up as they would occasionally adhere to the underside of the upper eyelid. Frequently there would be some clear mucous or discharge from the eye, and some contact lens wearers would tell their eye doctor they kept seeing little spots on the surface of the lenses when they were handling them.

People have often admitted to me they turned their upper eyelids inside out as kids. For some unknown reason, girls more than boys, at least by admission. What was found in the 1980’s when inverting the upper eyelid is now referred to as Giant Papillary Conjunctivitis, or GPC. Usually it is referred to as GPC. There is a clear tissue that covers the white scleral part of your eye and extends underneath the eyelids as their surface lining. In GPC, giant papillae  (bumps of swollen tissue) form under the upper eyelid. These are described as giant but actually are about 1/3 millimeter in diameter. They do feel giant due to the highly sensitive nature of the clear tissue on the front of your eye, the cornea. Every blink rubs these bumps across the cornea and creates discomfort.

The cause of GPC has been disputed for years but most eye care providers agree there are two components, a mechanical irritation and an immunological reaction.

The lens edge constantly engages the underside of the eyelid with each blink that results in a form of low grade irritation and inflammatory reaction in a small percentage of contact lens wearers. There are probably multiple reasons such as how taunt or floppy the lid is, how the secretions make it more prone to slide over or stick to the lens, the variations in lid curvature that apply pressure to the lens at different areas, and if the conjunctiva tissue has a higher number of inflammatory mediators already present. Deposits on the lenses can also cause a mechanical type of reaction.

The immunological reaction is related to deposits that build up on the lenses. These can be your own tear lipids,proteins, preservatives in contact lens solutions that build up in the lens matrix, environmental allergens that build up on the lens, and in rare cases possibly the material the lens is made of. Since soft lenses are about half water they act like a sponge absorbing larger molecules and retaining them resulting in increasing levels over time.

Wearing the same pair of lenses for several years obviously caused an increase in this condition.  The hard lenses worn prior to soft contact lenses can still cause GPC, but because they are inert and do not absorb any water the incidence is very low. With the advent of extended wear, the eyes were given constant exposure to the mechanical and immunological irritants with no recovery time so the incidence started climbing again.

In the first era of contact lens technology lenses were frequently machined on a lathe when dry then re-hydrated. Bausch & Lomb developed spin casting the liquid material in a mold. Today automation and molding manufacturing techniques allow for much more precise and smooth lens edges. Lens that were hand inspected under a microscope in the past are now quality controlled by automated systems. These have been quantum  improvements in lens quality that have helped decrease lens edge induced GPC problems.  Extended wear contact lens materials are starting to be designed today to help resist deposits better.  For a number of years now the major contact lens manufacturers have been using large molecule preservatives that exceed the pore size of soft contact lenses. This greatly reduces the possibility of toxic preservatives inside the lens over time. Unfortunately, many generic solutions appear similar but often contain the older small molecule preservatives that can lead to GPC.

Even though the occurrence is much lower today, GPC can still be a major eye irritant and contact lens problem. There are several approaches to managing GPC. Switching to daily disposable lenses eliminates coating reactions completely since the lenses are thrown away daily and never exposed to disinfecting solutions. Usually, contact lens wearers with GPC have been wearing their contacts well beyond the suggested replacement cycle and become lax in cleaning the lenses. Returning to a normal 2-4 week replacement cycle and  discontinuing or decreasing overnight wear may be all that is required to return the eye to normal health.

Prescription eye drops are also a large part of treating GPC. A class of eye drops called mast cell stabilizers work to stabilize the cells membranes from releasing histamine that starts the inflammatory cycle. These eye drops are very safe and can be used year round when needed. Other options are available and today GPC is no longer the end of your contact lens career, only a small bump in the (eye) road.  Vision Insurance like Vision Service Plan Frequently offer plans that include medical treatment for conditions like GPC. You should do an annual review of all of your medical and vision coverage to make sure you are providing the best benefits you can for your family.

There is a new epidemic that is running rampant across the United States. Fortunately it is not contagious and not life threatening like the Swine Flu, but there is a tremendous cost in terms of loss of quality of life and vision. This epidemic is often referred to as Dry Eye Syndrome and effects millions of people with symptoms ranging from mild, vague discomfort to completely disabling pain and chronic blurred eyesight.The Dry Rye Epidemic has multiple causes.

• Time spent by adults on computers and youth on video games dramatically lowers the normal blink rate and causes the eyes to dry out faster than normal.
• Historically, before mass consumption of processed foods, for every unit of omega-3 fat we consumed in our diet we ate 1 to 4 units of omega 6. Today that ratio has shifted to 20-30 times more omega 6 fats in our diets than omega-3. This has caused an outbreak of disease of the eyelid margins and resultant poor tear film quality.
• As the population has aged there has been an increase due to normal, age related decreases in tear production.
• The large increase in prescription medication use has resulted in numerous drugs being used that contribute to dry eyes. Medications for blood pressure, depression, allergies, pain, and many other conditions can have drying effects.
• Millions of women treated with hormonal replacement therapy in the past may have increased the dry eye epidemic.
• With the shift to industrialized society, working indoors the patterns of airflow and humidity have been altered and effect the incidence of dry eyes.
• The long term shift away from water consumption towards caffeinated beverages and colas aggravates dry eyes in some individuals.
• Even the increase in obesity leads to low grade inflammation in the body which can decrease tear production.
• Many eyedrops, prescription and over the counter, can  cause or aggravate dry eyes to the point that some patients discontinue their treatment and suffer sight loss.
• Perhaps the worse culprit in the dry eye epidemic is LASIK eye surgery. The nerves that drive the eyes to blink are cut by the surgery and dryness is a frequent complaint after surgery. The dryness sometimes persists and requires long term treatment.

Fortunately we have many options today, including prescription eye  medications, new contact lens materials, glaucoma  eye drops designed for dry eyes, nutritional supplements, and even  micro-plugs implants for the tear ducts to help increase the basal level of moisture. If you feel you have symptoms of dry eyes please call and request an appointment for a dry eye evaluation. Your vision insurance service plan may provide coverage for dry eye treatment.

Symptoms could be any of the following:

1. Burning or stinging if the eyes
2. Eyes that intermittently water excessivley
3. Eye that feel griity at times
4. Vision that blurs up for brief periods of time
5. Pink or red eyes
6. Vision discomfort that gets worse as the day progresses
7. Developing intolerance to contact lenses
8. An increase in the normal level of itchy eye allergies
9. Frequent styes and eye infections

Research on eye genes that cause or predispose individual to eye disease is a fast growing area which will probably find it’s way into your eye doctors office in the next 5-10 years. Most genetic tests are not perfect in the sense they are not diagnostic of an eye disease, but they frequently tell optometrists who may be more susceptible to acquiring the vision problem

in the first place, or which individuals may be prone to more severe forms.

Almost 500 genes have been identified that contribute to diseases of the eyes.  Mutations in the DNA  associated with a number of eye diseases, including glaucoma, cataracts, strabismus, corneal dystrophies different types of retinal degeneration. Diseases thought to be untreatable in the not to distant past are now being  targeted for future gene-based therapies.

Family members with relatives affected with genetic based eye diseases may want to know their risk factors and also for any future children. Unfortunately, testing is not readily available today, but the National Eye Institute is working to develop member labs to have this service  readily available at some point in the future.

The program initiated  to undertake this effort is referred to as the eyeGENE^TM program. It is a national progrma oordinating center, a centralized repository for blood/DNA/cell lines, several CLIA laboratories and a shared genotype / phenotype database. The goal of the NEI is to augment, not diminish, existing university-based and commercial ventures, while providing a new entry portal with rapid, reliable, and easy access to medical professionals.

Access to patient samples coupled to anonymous phenotypic data will augment the pace of ophthalmic genetics research, leading to improved medical decision making, clinical trials, and treatments for genetic eye diseases.

NASA and the National Eye Institute have been working together to develop a  non-invasive method to measure very early development of cataracts and monitor any progression. This is important to astronauts receiving higher daily dose of radiation, especially on a long mission such as the future Mars flight,  but there are great potential applications for preventing and treating cataracts in the future. The crystalline lens in the eye is composed largely of water but there is a class of  proteins present  known as alpha-crystallins.

The amount of  Alpha-crystallin Proteins in the eye are largely fixed at birth, we don’t produce more. They function to  a help the lens maintain it’s refractive index, which allows it to focus light on the retina so we can clearly see images. They also act as so called chaperone’s, dating the bad proteins that breakdown in the lens from oxidative stress. By joining up with theses proteins they prevent cross linking  between large numbers of damaged proteins and other damaged cellular substances that can develop into large clumps and form opacities in the lens. These capacities can develop large enough in size that they start to interfere with your eyesight and become clinically referred to as cataracts.

The new instrument measures how much Alpha-crystallin Proteins scatter light and can detect their levels and changes  over time. Now the potential exists to measure changes in response to environmental factors.

We have shown that this non-invasive technology that was developed for the space program can now be used to look at the early signs of protein damage due to oxidative stress, a key process involved in many medical conditions, including age-related cataract and diabetes, as well as neurodegenerative diseases such as Alzheimer’s and Parkinson’s," said NASA’s Dr. Ansari. "By understanding the role of protein changes in cataract formation, we can use the lens not just to look at eye disease, but also as a window into the whole body."

Oxidative Stress is caused by an imbalance between the production of Reactive oxygen species and your bodies capaictiy to neutrlaize them, the reactive intermediates, and repair any resultant cellular damage. Oxidative stress results from UV, radiation, drugs, chemicals,smoking, dietary components and other environmental factors that create oxygen is states where free electrons readily bind to cellular substances, Free radicals are atoms, molecules, or ions with unpaired electrons that also readily bind to proteins, lipids, and the DNA of our cells. When the threshold of repair is passed, and the Alpha-crystallin Proteins become lowered with age to the point where they can’t adequately act as chaperone’s to prevent these damgaed proteins from aggreagting into the clumps, you will likley develop cataracts.

Hopefully we can start to clarify some of the lingering questions and move forward into the arean of cataract prevention and reversal. Antioxidants have held out great hope for cataract prevention and anti-aging in general, but questions have been raised in some recent studies about the capacity of antioxidants to help.There is even a small school of thought that believes low doses of oxidative stress is essential in prolonging life. At this point, the only certainly is Vitamin A is contraindicated in smokers.

I still strongly believe in the value of antioxidants in a preventative role. Some studies have shown lutein and zeathin have reduced the incidence of cataract formation. Extensive studies are underway to test their role in treating macular degeneration. Vitamin C is still on my list as anti-catarogenic. One factor to keep in mind is natural is not always good. St John’s Wort does have some properties that my causes cataracts and sunglasses need to be worn and sunlight limited if you are taking St Johns Wort (commonly used for depression). This does not appear to be a strong causative factor but one to consider and compensate for when working in the sun.

Other lifestyle factors such as smoking, obesity, and eating a high glycemic index (highly refined high sugar,highly refined foods) are controllable risk factors. While I have not see the reasons published, presumably oxidative stress is the common factor. Smoking is know ot decrease antioxidants systemically  in your body, the cellular damage from free radicals is obvious in the loss of  skin elasticity. Even visible blue light causes oxidative damage in the retina and probably in the lens, Lutien and xeanthin may act as antioxidants in the lens to help prevent cataract development.

We can look forward to a great future in early detection (prior to visible damages) from cataracts and determining what lifestyle, dietary,and potential drugs ans supplements may prevent cataracts at some point in the future.

For now diet,exercise, a healthy body weight, a daily supplement (without the Vitamin A for smokers,  added Lutien, Zeanthin, and vitamin C is probably your best bet. And everything you can get from food (such as Lutein from spinach or other foods with high levels is presumably better than a pill.—Add protect your eyes from the UV sunlight with quality sunglasses or UV blocking contact lenses.

The next time you see your Eye Doctor they may just be measuring your alpha-crystallins levels, especially if you signed up for that 3 year cruise to Mars.

Melanocytes are specialized cells that contain the pigment found in our hair skin, eyes, and other area of the body. The eye has melanocytes in the iris, retina, and the choroidal layer under the retina that supplies it with blood. Underneath the retina is a layer of cells referred to as the retinal pigmented epithelium. These cells interact with the photoreceptor cells, the rods and cones that register light you see and turn it into electrical impulses. Melanin is the pigment and it comes in two different forms. In the retina, melanin acts as an antioxidant to help protect the tissue from free radicals that can damage the cellular DNA.

Various detrimental influences can reduce this protective function and may even cause it to accelerate damage from free radicals. Ultraviolet exposure, blue visible light, and high levels of oxidative stress can cause cell damage and increase the rate of cell death. An article by Meyskens FL, Farmer P, Fruehauf JP  suggested that this may be a contributory factor in macular degeneration and choroidal melanomas.

Melanocytes also populate our skin where they protect the underlying levels from ultraviolet damage. UV-B exposure is an essential step in producing the active form of  vitamin D. Darker skinned intervals have more UV screening and subsequently are more at risk for low levels of vitamin D. When you wear highly protective sunscreen the same effect occurs, lower levels of UV are absorbed by the skin and the proactive form of Vitamin D does not get its needed UV-B exposure to form. It is a very narrow band of UV-B that is needed, not the entire spectrum.

Vitamin D degeneration is related to multiple forms of cancer and other health problems. Macular degeneration may have an association with lowered vitamin D. One possibility is the overall reduction in UVB on the skin from sunscreen, living indoors, and poor dietary habits results in systemic changes in vitamin D levels that precipitates cellular changes in the retina unrelated to the melanin in the eye. Another possibility is lowered systemic levels of vitamin D resulting in decreased melanin production in the retina. This could lead to an overload to the pigmented epithelial cells from oxidative stress and UV exposure inside the eye, degrading the functional capacity of the melanin to protect the retina.
The irony is UV exposure is a risk factor for cataracts and macular degeneration and we are always encouraging eye protection against UV (and rightfully so given today’s evidence). With the known association of skin cancer and UV exposure it is not prudent to drop recommendation for sunscreen and limiting sun exposure.

At some point there will be better answers. For now, some mild daily exposure to UV with eyewear that includes UV protection is something you should discuss with your eye doctor and dermatologist or family physician. Vitamin D supplementation during winter months and in geographic locations that get limited sunlight should also be considered with your healthcare providers.  Perhaps sunscreen lotions will be developed that allow the narrow band of UV-B needed to pass through in the future.  Many people have vision insurance coverage like Vision Service Plan that provides coverage for eyeglasses. Even if your prescription is minor, having protection against UV and visible blue light is good preventative medicine if you spend time outdoors. And if you spend six months on a submarine or live underground you should examine your options-and maybe see a psychologist!

Glaucoma is a complex multi-factorial disease. In plain English, that means it is not one disease and not caused by one factor only. Recent knowledge has made us acutely aware that eye pressure is not the determining factor in the diagnosis of glaucoma. When the pressure inside the eye was above 21 in the past glaucoma was thought to be present. Today we know that some individuals will never develop glaucoma even though their eye pressure readings may stay in the 30’s while other patients cannot tolerate normal pressures without sustaining sight loss. Glaucoma is more of a vascular disease of the optic nerve of the eye. When the auto-regulation of the blood supply starts to fail, vision begins degrading. High eye pressures do cause compression of the blood vessels supplying the nerve, but healthy blood vessels with good autoregulatory mechanisms can sustain very high pressures. Eye pressure is not static and can vary throughout the day. When we read it once when we are at the optometrists office it is only a thin slice of what your pressure range could be over a 24 hour period.

The Human Genome Project mapped the human gene structure and was an enormous undertaking completed in 2003 taking 13 years and sequencing over 3 billion codes of base pair information. This has opened the doors to tremendous future strides in treating all diseases. There is a chromosome with a  gene that codes for the production of a protein called myocilin-a protein that makes up part of the  structure of the trabecular meshwork. This meshwork is responsible for keeping the fluid balance in check by allowing continual drainage. When something goes awry with the drainage the pressure goes up increasing your risk for developing glaucoma. Ocugene is a company that has developed a  test for defects in the myocilin/TIGR gene(GLC1A). Unfortunately, this gene is only responsible for about 4% of the cases of glaucoma. It can be useful when there is a suspected family history since patients with this genetic marker tend to have rapidly developing glaucoma and should be treated more aggressively. It also tends to be more commonly associated with glaucoma under the age of 40.The WDR36 (GLC1G) gene has also had mutations that appear to be associated with glaucoma. The optieurin gene(GLC1E) has reportedly been associated with an increased incidence of glaucoma in patients with normal pressures. One uncommon form of glaucoma know as exfoliation has also has seen the development of a genetic marker test, but due to the rarity of this condition it is not widely used .

All together, probably less than 10% of glaucoma has a direct genetic cause, and due to the expense of genetic testing it is rarely utilized. The complexity of testing is compounded by the fact that numerous defects at each gene can ocurr, and sometimes it may take two or more genes with flaws to create glaucoma. Even the most accepted genetic factor, the myocilin gene, may cause glaucoma from defects in areas other than the trabecular meshwork. It is very early in the age of genomics. Perhaps the greatest benefits will not be in diagnosing glaucoma but in tailoring treatment and actually curing some forms of glaucoma in the future.

General health issues are the most important risk factors, and some you can control. Smoking and cardiovascular diseases are high risk factors for developing glaucoma. Make sure you stay fit and have well controlled blood pressure. Keep preventative appointment and regular eye exams to monitor the eye pressure. Age is a risk factor but consider it a good one. A longer life is usually better all things considered! Most vision insurance plans  like Vision Service Plan, Medicare, and many others cover preventative annual eye examinations.

Twitchy eye? Many people become concerned when they start having an eyelid that twitches intermittently or even constantly. This may occur for weeks, months, or even years. Typically it does not occur constantly and has been coming and going for a month or so when the patient finally show up at the eye doctors office concerned they have acquired a serious vision problem. Most of the time after a lengthy eye exam and detailed analysis an accurate diagnosis is made-benign eye twitch. Essentially that means the doctor has no idea what is causing your eye problem but has ruled out  serious diseases

Sometimes a cause for eye twitching is found. Anything that causes ongoing low grade irritation of the eye can elicit twitches. An eyelash growing in towards the eye, dry eyes, a foreign body such as small particles of vegetation, insects, metal, etc. can all be provoke twitching eye lids. Some prescription medications and serious medical problems can precipitate eye twitches.

A well kept secret today is there are effective treatments for benign eyelid twitches. Specific types of topical antihistamine prescription eye drops frequently can alleviate the twitch, even though an eye allergy is usually not the cause. Reducing stress may help in many cases. Stress reductions techniques that help can include improving your sleep cycle by eliminating caffeine, relaxation techniques, and looking for areas to reduce the areas of high stress in your life. Cool packs on you eyes for 5-10 minutes several times per day can be tried as a palliative measure. Cold compresses probably reduce the nerve transmissions responsible for the eye twitching. If cool packs don’t work, warm packs sometimes will. Artificial non preserved tears can be used several times per day; they are not harmful and if a dry eye is part of the problem they could provide needed relief. Often a placebo effect can occur with artificial tears and is beneficial even when you are aware that it is a placebo.  Medications that can evoke eye twitches include stimulant drugs for attention deficient disorder, medications for Parkinson’s disease, some cold medications, and even asthma inhalers. If the problem is severe you should discuss your medications with your physician.

Some limited studies have shown complimentary alternative medicine may be useful is certain patients. Acupuncture has reportedly helped some people. Most simple eye twitches are probably similar to the twitches you have from time to time in you legs and arms. These are often due to muscle fatigue and electrolyte imbalances. Make sure you are well hydrated and have adequate magnesium, potassium, calcium, and vitamin D in your diet. Some healthy food to add are bananas, raisins, apricots, cantaloupes and leafy green vegetables like spinach. Avocado lovers can benefit also. Gentle stretching of leg muscle spasms has become the accepted standard replacing gentle massaging. You might try the eye equivalent of gentle stretching by slowly closing your eye, pause briefly, then open it slightly larger than normal and pause for a second. Try doing ten repetitions ten time per day.

When eye twitches become severe and spasm the eye closed it can be caused by an over stimulation of the brain center responsible for blinking. This has a genetic predisposition so if you have other family members with similar problems that is significant information you should tell your optometrist. Usually it begins with more frequent blinking and progresses to eye closure spasms. When eyelid twitches become constant and severe, they may keep the eye closed and interfere with vision. Injections of Botox, the face lifting drug, are a tremendous asset in these rare cases. Although many people are frightened by the though of injecting something into their eyelid that is so toxic it is considered a potential terrorist weapon, the doses used resemble homeopathy and are exceedingly safe. It would probably take at least 30 to 40 thousand doses at once to be lethal. Drugs in the same class as valium have had some success in treatment. As a last resort eyelid surgery can be attempted.

Uncontrollable, progressive eye spasms that effect you eye sight need further evaluation for serious underlying neurological diseases. The majority of cases are benign and the initial visit to an eye doctor can help you on the road to recovery.

Pseudotumor cerebri is an eye condition that can be confused with a brain tumor due to swelling of the optic nerve. Like a brain tumor, the fluid inside the skull that cushions the brain and flows around the spinal column develops elevated pressure.  It is also referred to as Idiopathic Intracranial Hypertension or Benign Intracranial Hypertension. It is more prevalent in  women between the ages of 20 and 50. Symptoms of pseudotumor cerebri are usually an undiagnosed chronic headache, and in more severe cases there may be visual symptoms such as double vision. Also nausea and vomiting may occur. There is an unusual effect of  pulsating sounds within the head that are synchronous with the heart rate referred to as   Pulse-synchronous tinnitus.

A routine eye exam is where the initial diagnosis of mild cases of pseudotumor cerebri is often first made. The optic nerve that enters the back of the eye appears elevated in both eyes, a condition referred to as papilledema. Because the nerve is an extension of the brain and enclosed by the same tissues and fluid that cushion the brain, elevation in the pressure inside the brain also cause the nerve to swell. Since most cases occur in young to middle age overweight females, an elevated nerve with a history of chronic headaches and otherwise healthy is often indicative of pseudotumour cerebri. Other visual symptoms include double vision, brief periods of blurred vision or dim vision, and occasionally patient will have temporary episodes of blindness in one or both eyes. Changes in posture such as suddenly standing up or bending over may elicit symptoms, as may coughing or sneezing.

Double vision may occur when looking to the side. This is caused by a defect in abduction or the ability of an eye to turn out. due to a restriction in the capacity for one or both eyes to turn out. This presents a confusing picture when taken out of context because it is not due to damage to the abducens nerve (6th Cranial Nerve)  that controls the eyes outward motion. In this case, the double vision is called a false localizing sign. Pain can occasionally be associated with eye movements.

Rarely, the pressure can become very high and cause severe problems with vision and alterations in  levels of awareness. Most of the time truly is benign idiopathic intracranial hypertension and is managed by weight loss and occasionally medications. Sometimes discontinuation of certain medication may resolve the problems. The most severe cases may require a shunt to drain the increased fluid from the ventricles in the brain into the abdominal cavity.
