What is a Cataract? A cataract is the clouding of the crystalline lens in your eye. This opacity obstructs the passage of light resulting in a reduction of clear vision. Normally, light passes through the clear lens and is focused onto the Retina. However, the natural aging process can cause the lens to become cloudy, or milky. The cataract blocks the passage of light through the eye and causes distorted or blurred vision, glare, or difficulty seeing in poor lighting conditions.



There are three types of cataracts: » A nuclear cataract forms in the lens. Those over 65 are more prone to develop this type of cataract. More than half of all Americans over the age of 65 will develop a cataract. » A cortical cataract forms in the lens, then grows from the outside to the center of the lens. Diabetics are more prone to develop this type of cataract. » A subcapsular cataract forms in the back of the lens. Those with diabetes, high hyperopia (Far-sightedness) or retinitis pigmentosa may be at a higher risk to develop this type of cataract.

It is not known why cataracts occur in all instances but studies on the cause of cataracts will soon teach us how to more successfully treat and prevent them. The most commonly known type of cataract is age related. You may not notice a slight change in your vision, as cataract starts out very tiny, but as it grows from the size of a pin head, you may notice that your vision is becoming blurry, and you may feel you are looking through dirty lenses. Object edges may appear to fade into one another and colors may not appear as bright as they should.		The most common symptoms of a cataract are: » Cloudy or blurry vision. » Problems with light. » Problems with headlights that seem too bright. » Problems with glare from lamps. » Problems with very bright sunlight. » Colors that seem faded. » Poor night vision. » Double or multiple vision. » Frequent changes in glasses or contact lenses. » Eyeglasses are no longer effective. » Contact lenses are no longer effective.

Glaucoma Glaucoma is actually a group of eye diseases that lead to damage of the optic nerve (the nerve fiber that carries information from the eye to the brain), which can then lead to vision loss and the possibility of blindness.



Optic nerve damage usually occurs in the presence of high intraocular pressure, but glaucoma can occur with normal or even below-normal eye pressure. There are two main forms of glaucoma: open-angle (which is the most common form and affects approximately 95% of individuals) and closed-angle. There are also several other varieties of glaucoma, including secondary, normal-tension, congenital, pseudoexfoliation syndrome, juvenile, neovascular, pigmentary, and irido-corneal-endothelial syndrome (ICE syndrome). Worldwide, it is estimated that about 66.8 million people have visual impairment from glaucoma, with 6.7 million suffering from blindness. In the United States, approximately 2.2 million people age 40 and older have glaucoma, and of these, as many as 120,000 are blind due the disease. The number of Americans with glaucoma is estimated to increase to 3.3 million by the year 2020. Vision professionals estimate that half of those affected may not know they have it because symptoms may not occur during the early stages of the disease. Glaucoma is a leading cause of blindness among African Americans and Hispanics in the United States. African Americans experience glaucoma at a rate of three times that of Caucasians and experience blindness four times more frequently. Between the ages of 45 and 64, glaucoma is fifteen times more likely to cause blindness in African Americans than in Caucasians. High-risk factors for open-angle glaucoma, the most common form of the disease, include being an African American and over 40, having a family history of the disease, and being over 60 for the general population. Those who are very nearsighted, have a history of diabetes, have experienced eye injury or eye surgery, or take prescription steroids also have an increased risk of developing glaucoma. It has also been suggested that individuals with Japanese ancestry may be at a greater risk for normal-tension glaucoma, and that those of Asian and Eskimo descent may have a greater risk for closed-angle glaucoma. Open-angle glaucoma, by far the most common form, has no symptoms at first. At some point, side vision (peripheral vision) is lost and without treatment, total blindness will occur. Closed-angle glaucoma (acute glaucoma) results from a sudden, complete blocking of the fluid flowing out of the eye. Symptoms may include severe pain, nausea, vomiting, blurred vision, and seeing a rainbow halo around lights. Closed-angle glaucoma is a medical emergency and must be treated immediately or blindness could result rapidly. Currently, there is no "cure" for glaucoma; however, early diagnosis and treatment can control glaucoma before vision loss or blindness occurs. There are several tests that can help your eye care professional detect glaucoma; these include a visual acuity test, visual field test, dilated eye exam, tonometry (which measures the pressure inside of the eye), and pachymetry (which uses ultrasonic waves to help determine cornea thickness). Individuals at high risk for glaucoma should have a dilated pupil eye examination, and a visual field test annually. Early treatment for open-angle glaucoma will usually begin with medications (pills, ointments, or eyedrops, for example) that either help the eye to drain fluid more effectively or cause it to produce less fluid. Several forms of laser surgery can also help fluid drain from the eye. Incisional surgery to create a new opening for fluid to drain is usually performed after the other treatment options have failed. When a patient has glaucoma or is at high risk for developing the disease, physicians may document how the optic nerve changes over time by making drawings, taking photographs, or using a new technique called optic nerve imaging. Scanning laser polarimetry (GDx), confocal scanning laser ophthalmoscopy (Heidelberg Retinal Tomograph or HRT III), and optical coherence tomography (OCT) are all examples of optic nerve imaging techniques. The patient’s eye care professional will make the determination as to which method(s) to use. New research is focusing not only on lowering pressure inside the eye, but is also exploring medications that will protect and preserve the optic nerve from the damage that causes vision loss as well as the role of genetic factors. There has been progress in understanding the genetics of glaucoma in the last few years. Genes have been found that are associated with congenital glaucoma, juvenile glaucoma, normal-tension glaucoma, adult-onset open-angle glaucoma, pigmentary glaucoma, and other conditions that are associated with secondary glaucoma.

What is a Dry Eye?

Many times in our lifetime, we will experience a "foreign body sensation" in our eye. That usually happens if the wind blows dust, an allergen or a foreign body into our eye or under an eyelid. This should not be dismissed as just an uncomfortable feeling. It needs to be remedied. It cannot be allowed to linger or fester.

For many, the feeling of grittiness, dryness, burning or stinging or even excessive tearing cannot be relieved simply, or with over the counter methods. It may be the sign of a chronic condition known as dry eye syndrome. Yes, even tearing eyes are a sign of dry eye.

The tears your eyes produce are necessary for overall eye health and clear vision. Dry eye means that your eyes do not produce enough tears or that you produce tears that do not have the proper chemical composition. Dry eye is more common as we age. It can also be caused by blinking or eyelid problems, medications like antihistamines, oral contraceptives and antidepressants, a dry climate, wind and dust, general health problems like arthritis or Sjogren's syndrome and chemical or thermal burns to your eyes.

If you have dry eye, your symptoms may include irritated, scratchy, dry, uncomfortable or red eyes, a burning sensation, excessive tearing, blurred vision, or a feeling of something foreign in your eyes. Excessive dry eyes may damage eye tissue, scar your cornea (the front covering of your eyes) and impair vision and make contact lens wear difficult.

Any condition that reduces the production, alters the composition, or impedes the distribution of the preocular tear film (POTF) may cause a noticeable irritation to the structures of the front surface of the eye and a degradation of vision. These conditions are often related to problems with the structure or function of the eyelids, cornea, or conjunctiva. Depending upon the severity of symptoms, individuals may be limited in their ability to see clearly and comfortably and may be at increased risk of developing secondary infection or chronic inflammation that may not respond to treatment.

The two most commonly encountered ocular surface disorders are tear film disorders and blepharitis. Additional subclassifications include those dry-eye states associated with systemic connective tissue disorders, specifically Sjogren syndrome (SS). With regard to lipid deficient tear-film disorders, the involvement of meibomian gland dysfunction (MGD) has been proposed.

An estimated one-fifth of visits to eye care practitioners are related to ocular complaints secondary to dry eye, and as many as 25 percent of American adults may be affected by dry eye or have dry eye symptoms. These statistics indicate a significant need for access to professional care.

We perform specific tests to assist in differentiating the various forms of tear film abnormalities and identifying potential treatment strategies. Careful clinical observation, accurate diagnosis, and appropriate intervention can eliminate or minimize the deleterious effects of ocular surface disorders on the quality of life.

Ocular Allergies

Allergies affect over 20% of the general population and are on the rise in many developed countries. The specific reason for the increasing prevalence of allergies has not been determined; some believe it is due to the effects of pollution in urban areas while others consider that modern lifestyles don't allow for enough childhood exposure to allergens to become acclimated to them.

Allergies can take many forms, affecting various organs or tissues. Ocular allergies are among the most
bothersome forms of allergic reaction. The characteristic signs and symptoms of ocular allergies include:

• Itching

• Redness

• Watery eyes

• Swelling of the eyes and eyelids

Ocular allergies are often accompanied by allergic rhinitis (nasal symptoms). This is partly due to the fact that the eyes and nose are so closely connected by the tear ducts; substances that enter the eye can then flow downward into the nose. Symptoms include:

• Runny nose

• Sneezing

• Congestion

Eye allergies are no different than allergies that affect your sinuses, nose or lungs. When an allergen comes in contact with your eyes, your body releases histamine - a chemical produced in reaction to a substance that the immune system can't tolerate. special cells called mast cells make histamine. These cells are present throughout the body but are highly concentrated in the eyes. Location of allergy symptoms depends somewhat on where the allergen has come into contact with your body. Ocular allergens tend to be airborne (as are most other allergens).


The most frequent allergic triggers include:			Some triggers irritate the eyes but are not true allergies:
• Pollen			• Cigarette smoke
• Pet hair or dander			• Perfume
• Dust			• Diesel Exhaust
• Some medicines

The Eyes' Response To Ocular Allergens

When exposed to these allergens, the response in the eye is nearly immediate:
• First, itching sets in and can become persistent and extremely bothersome if exposure to the allergen is continued.

• Shortly after itching, redness of the eyes follows and can last somewhat longer, as the blood vessels of the eye are slower to recover.

• The swelling of the eyes and eyelids comes to its peak later than the itching, as swelling is also caused by the blood vessels letting fluids out into the tissue around them. Swelling is the sign of ocular allergies slowest to disappear, due to the time it takes for the displaced fluid to be removed.

• The itching can be considered the most uncomfortable symptom, whereas the swelling and redness are most bothersome in terms of appearance.

Diabetic Retinopathy (REH-tih-NOP-uh-thee) Diabetic Retinopathy is the medical term for the most common diabetic eye problem. Diabetic retinopathy is the leading cause of blindness in American adults. It damages the blood vessels in the retina, the light-sensitive nerve tissue in your eye that sends visual images to your brain.


Blurred vision or temporary blindness can occur when blood vessels weaken, bulge and leak fluid into surrounding tissue, causing swelling - a condition called macular edema. Abnormal new blood vessels may often, grow on the retina, where they can bleed into the eye and block vision. As the disease progresses, the retina can detach from the eye, resulting in permanent blindness. Irreversible vision loss can be prevented with early detection and treatment. This is just one of the reasons it is so important to have your eyes checked on a regular basis. In addition to testing your vision, we will look for any signs of eye disease. Retinal damage happens slowly. Your retinas have tiny blood vessels that are easy to damage. Having high blood glucose and high blood pressure for a long time can damage these tiny blood vessels. First, these tiny blood vessels swell and weaken. Some blood vessels then become clogged and do not let enough blood through. At first, you might not have any loss of sight from these changes. This is why you need to have a comprehensive eye exam once a year even if your sight seems fine. As diabetic retinal problems get worse, new blood vessels may grow. These new blood vessels are weak. They break easily and leak blood into the vitreous of your eye. The leaking blood keeps light from reaching the retina. You may see floating spots or almost total darkness. Sometimes the blood will clear out by itself, but you might need surgery to remove it. Over the years, the swollen and weak blood vessels can form scar tissue and pull the retina away from the back of the eye. If the retina becomes detached, you may see floating spots or flashing lights. You may feel as if a curtain has been pulled over part of your vision. A detached retina can cause loss of sight or blindness if you don't take care of it right away.

What is Strabismus? Strabismus is a visual problem in which the eyes are not aligned properly and point in different directions. One eye may look straight ahead, while the other eye turns inward, outward, upward or downward. The eye turn may be constant, or it may come and go. Which eye is straight or misaligned may switch or alternate.

Esotropia

Exotropia

Hypertropia

Strabismus is a common condition among children. About 4 percent of all children in the United States have strabismus. It can also occur later in life.

Strabismus occurs equally in males and females. It may run in families; however, many people with strabismus have no relatives with the problem.

The exact cause of strabismus is not fully understood. In some cases, strabismus may be due to problems with the muscles controlling eye movement.

Six eye muscles that control eye movement are attached to the outside of each eye. In each eye, one muscle moves in the eye to the right, and one muscle moves the eye to the left. The other four muscles move it up or down and at an angle.

To line up and focus both eyes on a single target, all of the muscles in each eye must be balanced and working together. In order for the eyes to move together, the muscles in both eyes must be coordinated. The brain controls these muscles.

With normal vision, both eyes aim at the same spot. The brain then combines the two pictures into a single, three-dimensional image. This three-dimensional image gives us depth perception.

When one eye is out of alignment, two different pictures are sent to the brain. In a young child, the brain learns to ignore the image of the misaligned eye and sees only the image from the straight or better-seeing eye. The child then loses depth perception.

Adults who develop strabismus often have double vision because their brains have already learned to receive images from both eyes and cannot ignore the image from the turned eye. A child generally does not see double.

In some cases, strabismus may result from problems in the brain. Sometimes, a child's brain may not be correctly combining the two images it receives from the eyes. In rare cases, a tumor may affect how the brain processes visual information. Often children experience strabismus as a result of problems that can be easily treated with glasses.

Macular Degeneration



Age-related Macular Degeneration (AMD) is an eye disease causing clear vision to fail in millions of older People. When electrical signals from the retina (the inner layer of the eye that captures light and turns it into electrical signal) are received by the brain through the optic nerve, they are translated into images Age related Macular Degeneration is traditionally described as a form of the disease which affects individuals over the age of 55 years. However, we have recently discovered that a significant number of these individuals may have a major genetic component that contributes to the disease. There are 2 types of AMD, dry and wet. Dry AMD is more common, causing about 90% of AMD. It can develop so gradually that in the beginning stages you might not notice changes in vision. Wet AMD is less common (about 10% of cases) but is more severe and may progress more rapidly. Dry Macular Degeneration, in which the cells of the macula slowly begin to break down, is diagnosed in 90 percent of the cases. Yellow deposits called "drusen" form under the retina between the retinal pigmented epithelium (RPE) and Bruch’s membrane, which supports the retina. Drusen deposits are "debris" associated with compromised cell metabolism in the RPE and are often the first sign of Macular Degeneration. Eventually, there is a deterioration of the macular regions associated with the drusen deposits resulting in a spotty loss of "straight ahead" vision. Wet Macular Degeneration occurs when abnormal blood vessels grow behind the macula, then bleed. There is a breakdown in Bruch’s membrane, which usually occurs near drusen deposits. This is where the new blood vessel growth occurs (neovascularization). These vessels are very fragile and leak fluid and blood (hence ‘wet’), resulting in scarring of the macula and the potential for rapid, severe damage. "Straight ahead" vision can become distorted or lost entirely in a short period of time, sometimes within days. Wet macular degeneration accounts for approximately 10% of the cases, however it results in 90% of the legal blindness. What does Macular Degeneration do to your vision? Macular degeneration is the imprecise historical name given to that group of diseases that causes sight-sensing cells in the macular zone of the retina to malfunction or lose function and results in debilitating loss of vital central or detail vision. What are the Symptoms of Macular Degeneration? Macular Degeneration can cause different symptoms in different people. Sometimes only one eye loses vision while the other eye continues to see well for many years. The condition may be hardly noticeable in its early stages. But when both eyes are affected, reading and close up work can become difficult. One of the easiest ways to screen for age-related macular degeneration (AMD) is to use an Amsler grid. An Amsler grid is a chart with lines and a dot at the center. Your doctor can give you an Amsler grid to use at home. For dry AMD (age-related macular degeneration), check your vision in each eye every day or as often as your doctor advises. It only takes a few seconds. What can you do if your diagnosed with Macular Degeneration? Modify environmental risk factors that we know about. You should: • Eat a low-fat, low cholesterol diet. • Wear sunglasses with UV protection. • Eat at least two servings of leafy dark green vegetables per day. • Do not smoke and avoid exposure to secondhand smoke. If you are post-menopausal, you should consult with your physician concerning estrogen replacement therapy. This may have a favorable impact upon cholesterol lipid levels that play a role in worsening the disease. Develop healthy habits! If you smoke, QUIT SMOKING! Exercising, maintaining normal blood pressure, cholesterol levels and eating a healthy diet is a step in the right direction. Eat food and-or supplements rich in vitamin E,C and Lutein. Lutein is a plant antioxidant found in high quantities in spinach, kale and other dark green, leafy vegetables. People who eat fish and green leafy vegetables may be at lower risk of AMD. There is no treatment for early dry AMD, although a particular combination of supplements (zinc and antioxidant vitamins) may slow progression in some people with more advanced disease. Early intervention for wet AMD can delay progression.
