Eye Health & Diseases

Allergy

An eye allergy is the eye’s overreaction to a substance that it thinks will harm it. Dust, for example, is harmless to most people, but to allergy sufferers it is a brutal assault that the eye tries to flush out with tears and mucus.

Eye allergy symptoms may include itching, redness, eyelid swelling and tearing. Nasal congestion occurs in some sufferers as well.

Avoidance of the allergen(s) is the best way to treat eye allergies. Try to identify the thing that causes the allergic reaction and avoid it. Symptoms should improve dramatically.

Dust mites, fecal particles and mold are the most frequent causes of chronic or recurrent allergic conjunctivitis. And because dust mites are often found in beds and linens, they can be controlled by using impermeable mattress and pillow covers and by changing bedding weekly and washing it in a hot water cycle.

During high pollen seasons, patients should limit their time outdoors in high-exposure activities.

For domestic pet sensitivity, the most effective measure is to eliminate the source by removing the pet from indoors, as carpets, upholstery, and clothing are all havens for animal allergens.

Allergy sufferers should also try and avoid non-specific irritants such as smoking, air pollution, and strong odors or perfumes.

If you feel you are suffering from allergies, we recommend setting an appointment with one of our optometrists as soon as possible. Our doctors will examine your eyes to determine if you have allergies and, if applicable, prescribe the best treatment.

Cataracts

While a comprehensive eye examination can determine for certain if you have a cataract forming, there are a number of signs and symptoms that may indicate a cataract.

Cataract treatment

 

 

 

 

 

 

 

    Among them are:

  • Gradual blurring or hazy vision where colors may seem yellowed
  • The appearance of dark spots or shadows that seem to move when the eye moves
  • A tendency to become more nearsighted because of increasing density of the lens
  • Double vision in one eye only
  • A gradual loss of color vision
  • A stage where it is easier to see without glasses
  • The feeling of having a film over the eyes
  • An increased sensitivity to glare, especially at night.

What is a cataract?

A cataract is a clouding of the normally clear crystalline lens of the eye. This prevents the lens from properly focusing light on the retina at the back of the eye, resulting in a loss of vision. A cataract is not a film that grows over the surface of the eye, as is often commonly thought.

 Why are they called cataracts?

Sometimes cataracts can be seen as a milkiness on the normally black pupil. In ancient times, it was believed this cloudiness was caused by a waterfall – or cataract – behind the eye.

 Who gets cataracts?

Cataracts are most often found in persons over the age of 55, but they are also occasionally found in younger people, including newborns.

 What causes cataracts?

It is known that a chemical change within the eye causes the lens to become cloudy. The change may be due to advancing age or it may be the result of heredity, an injury or a disease. Excessive exposure to ultraviolet or infrared radiation present in sunlight or from furnaces, cigarette smoking and/or the use of certain medications are also cataract risk factors. Cataracts usually develop in both eyes, often at different rates.

 Can cataracts be prevented and treated?

Currently, there is no proven method to prevent cataracts from forming. If your cataract develops to a point that daily activities are affected, you will be referred to an eye surgeon who may recommend the surgical removal of the cataract. Prescription changes in your eyewear will help you see more clearly until surgery is necessary, but surgery is the only proven means of effectively treating cataracts. The surgery is relatively uncomplicated and has a very high success rate.

 When will I need to have cataracts removed?

Cataracts may develop slowly over many years or they may form rapidly in a matter of months. Some cataracts never progress to the point that they need to be removed. Usually, you will be ready to have the cataract removed when it is having a significant adverse effect on your lifestyle. Our office will arrange a consultation with a surgeon who will decide on the appropriate time for removal. Most people wait until the cataracts interfere with daily activities before having them removed.

 What happens after cataract surgery?

You, along with your doctors, will decide on the type of post-cataract vision correction that you will use. Intraocular lens implants, inserted in your eye at the time of surgery, serve as a “new lens” and are the most frequent form of visual correction. In some cases, however, eyeglasses or contact lenses may also be needed to provide the most effective post-cataract vision.

Cataract surgery has now developed to the point where most procedures are completed in a day and overnight stays in hospital are unnecessary. The results are usually excellent and patients are often able to appreciate a significant improvement in vision almost immediately following surgery.

Conjunctivitis – Pink Eye

Red, watery eyes, inflamed lids, blurred vision and a sandy or scratchy feeling in the eyes may indicate that you have conjunctivitis. Pus-like or watery discharge around the eyelids may indicate an infectious form of the disease, commonly known as “pink eye.”

Conjunctivitis is an inflammation or infection of the conjunctiva, a thin, transparent layer covering the surface of the inner eyelid and the front of the eye. It affects people of all ages.

 What causes conjunctivitis?

The three main types of conjunctivitis are infectious, allergic and chemical. The infectious form, commonly known as “pink eye,” is caused by a contagious virus or bacteria. Your body’s allergies to pollen, cosmetics, animals or fabrics often bring on allergic conjunctivitis. Irritants like air pollution, noxious fumes and chlorine in swimming pools may produce the chemical form.

It is important to prevent spreading conjunctivitis. If contagious, measures can be taken to prevent spreading conjunctivitis to others.

  • Keep your hands away from your eyes;
  • Thoroughly wash hands before and after applying eye medications;
  • Do not share towels, washcloths, cosmetics or eyedrops with others;
  • Seek treatment promptly.

Small children, who may forget these precautions, should be kept away from school, camp and the swimming pool until the condition is cured. Certain forms of conjunctivitis can develop into a serious condition that may harm your vision. Therefore, it is important to have conjunctivitis diagnosed and treated quickly.

 

How is infectious conjunctivitis treated?

Infectious conjunctivitis, caused by bacteria, is usually treated with antibiotic eye drops and/or ointment. Other infectious forms, caused by viruses, can’t be treated with antibiotics and must be fought off by your body’s immune system. On occasions antibiotics may be prescribed to prevent secondary bacterial infections from developing.

How are the allergic and chemical forms of conjunctivitis treated?

The ideal treatment for both forms is to remove the cause of the allergy or irritation. For instance, avoid contact with any animal if it causes an allergic reaction. Wear swimming goggles if chlorinated water irritates your eyes. In cases where these measures won’t work, prescription and over-the-counter eye drops are available to help relieve the discomfort.

Diabetes

Diabetes, a disease that prevents your body from making or using insulin to break down sugar in your bloodstream, can affect your eyes and your vision. Fluctuating or blurring of vision, intermittent double vision, loss of peripheral vision and flashes and floaters within the eyes may be symptoms related to diabetes. Sometimes the early signs of diabetes are detected during a thorough eye examination.

Diabetes can cause changes in nearsightedness and farsightedness and lead to premature presbyopia (the inability to focus on close objects). It can result in cataracts, glaucoma, a lack of eye muscle coordination (strabismus) and decreased corneal sensitivity. The most serious eye problem associated with diabetes is diabetic retinopathy, which, if not controlled, can lead to blindness.

 What is retinopathy?

Diabetic retinopathy occurs when there is a weakening or swelling of the tiny blood vessels in the retina of your eye, resulting in blood leakage, the growth of new blood vessels and other changes.

 Can vision loss from diabetes be prevented?

Yes, in a routine eye examination, your eye care practitioner can diagnose potential vision-threatening changes in your eyes that may be treated to prevent blindness. However, once damage has occurred, the effects are usually permanent. It is important to control your diabetes as much as possible to minimize the risk of developing retinopathy.

How is diabetic retinopathy treated?

In the early stages, diabetic retinopathy can be treated with laser therapy. A bright beam of light is focused on the retina, causing a burn that seals off leaking blood vessels. In other cases, surgery inside the eye may be necessary. Early detection of diabetic retinopathy is crucial. It is routinely screened for in an eye examination.

Are there risk factors for developing retinopathy?

Several factors that increase the risk of developing retinopathy include smoking, high blood pressure, excessive alcohol intake and pregnancy.

How can diabetes-related eye problems be prevented?

Diabetes-related eye problems can be prevented by monitoring and maintaining control of your diabetes. See your physician regularly and follow instructions about diet, exercise and medication. A thorough eye examination when first diagnosed as a diabetic, at least annually thereafter, is recommended.

Dry Eye

If your eyes sting, itch or burn, you may be experiencing the common signs of “dry eye.” A feeling of something foreign within the eye or general discomfort may also signal dry eye.

What is dry eye?

Dry eye describes eyes that do not produce enough tears. The natural tears that your eyes produce are composed of three layers:

  • The outer oily layer, which prevents or slows evaporation of the tear film
  • The middle watery layer; which moisturizes and nourishes the front surface of the eye
  • The inner mucus layer, which helps maintain a stable tear film.

Dry eye may occur because the volume of tears produced is inadequate (we all produce fewer tears as we get older, and in some cases this can lead to dry eye symptoms). It may result because the composition of the tears has changed so that they are unstable and evaporate more quickly.

What causes dry eye

Dry eye symptoms can result from the normal aging process. Exposure to environmental conditions, as well as medications, such as antihistamines, oral contraceptives or anti-depressants, can contribute to the symptoms of dry eye. Or, dry eye can result from chemical or thermal burns to the eye. Dry eye may also be symptomatic of general health problems or other diseases. For example, people with arthritis are more prone to dry eye.

Will dry eye harm my eyes?

If untreated, it can. Excessive dry eye can damage tissue and possibly scar the cornea at the front of your eye, impairing vision. Dry eye can make contact lens wear more difficult since tears may be inadequate to keep the lenses wet and lubricated. This can lead to irritation and a greater chance of eye infection. Therefore, it is important to follow the recommended treatment plan.

How is it diagnosed?

During the examination, you will be asked about your general health, use of medications, and work and home environments to determine factors, which may be contributing to dry eye symptoms. This information will help decide whether to perform specific dry eye tests.

To test for dry eye, diagnostic instruments that allow a highly magnified view of your eyes or small strips of paper or thread and special dyes to assess the quantity and quality of the tears may also be used.

How is it treated?

Dry eye cannot be cured, but your eyes’ sensitivity can be lessened and measures taken so your eyes remain healthy. The most frequent method of treatment is the use of artificial tears or tear substitutes.

For more severe dry eye, ointment can be used, especially at bedtime. In some cases, small plugs may be inserted in the corner of the eyelids to slow drainage and loss of tears.

To keep dry eye symptoms in check, you and your optometrist need to work together. If you have increased dryness or redness that is not relieved by the prescribed treatment, let us know as soon as possible.

Glaucoma

What is glaucoma?
The build-up of pressure inside your eye leads to glaucoma. Aqueous fluid, which fills the space at the front of the eye just behind the cornea, is made behind the iris (the colored part of the eye) in the ciliary body. It flows through the pupil (the dark hole in the center of the iris), and drains from the ‘anterior chamber angle,’ which is the junction between the edge of the iris and the cornea. If this outflow of liquid is impaired at all, there is a build-up of pressure inside the eye that damages the optic nerve, which carries visual images to the brain. The result is a loss of peripheral vision. Thus, while glaucoma sufferers may be able to read the smallest line on the vision test, they may find it difficult to move around without bumping into things or to see moving objects to the side.

Tests for glaucoma are part of a comprehensive eye examination. A simple and painless procedure called tonometry measures the internal pressure of your eye. Ophthalmoscopy examines the back of the eye to observe the health of the optic nerve. A visual field test, a very sensitive test that checks for the development of abnormal blind spots, may also be completed.

What causes glaucoma

Some causes are known, others are not. Causes differ depending on the type of glaucoma. The exact cause of open-angle glaucoma, where the drainage channels for the aqueous appear to be open and clear, is not known. Closed-angle glaucoma can occur when the pupil dilates or gets bigger and bunches the iris up around its edge, blocking the drainage channel. An injury, infection or tumor in or around the eye can also cause internal eye pressure to rise either by blocking drainage or displacing tissues and liquid within the eye. A mature cataract also can push the iris forward to block the drainage ‘angle’ between the iris and the cornea. Glaucoma can occur secondarily to a number of other conditions, such as diabetes, or as a result of some medications for other conditions.

Who gets glaucoma?

Glaucoma most frequently occurs after age 40, but can occur at any age. If you’re of African heritage, you are more likely to develop open-angle glaucoma — and at an earlier age — than if you’re Caucasian. Asians are more likely to develop narrow-angle glaucoma.

You have a higher risk of developing glaucoma if a close family member has it or if you have high blood pressure or high blood sugar (diabetes). There is also a greater tendency for glaucoma to develop in individuals who are nearsighted. Those at heightened risk for glaucoma should have their eyes checked at least once a year.

Why is glaucoma harmful to vision?The optic nerve, located at the back of the eye, carries visual information to the brain. As the fibers that make up the optic nerve are damaged by glaucoma, the amount and quality of information sent to the brain decreases and a loss of vision occurs.

Will I go blind from glaucoma?

If diagnosed at an early stage, glaucoma can be controlled and little or no further vision loss should occur. If left untreated, side awareness (peripheral vision) and central vision will be destroyed and blindness may occur.

How is glaucoma detected?

The most scary thing about glaucoma is that it can steal your vision gradually and without your noticing. The best defense against glaucoma is a regular eye examination. Glaucoma most often strikes people over age 50. But it is recommended that during adult life everyone be tested at least every two years. Some people with glaucoma do experience symptoms, but symptoms vary depending on the type of glaucoma.

Primary open-angle glaucoma
By far the most common type, primary open-angle glaucoma develops gradually and painlessly. Since there are no early warning signs, it can slowly destroy your vision without your knowing it. The first indication may only occur after some considerable vision loss.

Acute angle-closure glaucoma
This results from a sudden blockage of the drainage channels within your eye, causes a rapid build-up of pressure inside your eye accompanied by blurred vision, the appearance of colored rings around lights and sometimes extreme pain or redness in the eyes.

How is glaucoma treated?
Glaucoma is usually treated with prescription eye drops and medicines. In some cases, surgery may be required to improve drainage. The goal of the treatment is to prevent loss of vision by lowering the pressure in the eye.

Will my vision be restored after treatment?
Unfortunately, any vision loss as a result of glaucoma is permanent and cannot be restored. This is why regular eye examinations are important.

Glaucoma cannot be prevented, but early detection and treatment can control glaucoma and reduce the chances of damage to the eye and a loss of sight.

Macular Degeneration

Age-related macular degeneration or ARMD is the most common cause of irreversible vision loss for people over the age of 60. It is estimated that 2.5 million people in developed countries will suffer visual loss from this disorder and that there are approximately 200,000 new cases diagnosed every year.

Macular degeneration is most common in people over the age of 65 but there have been some cases affecting people as young as their 40s and 50s.

Symptoms include blurry or fuzzy vision, straight lines like telephone poles and sides of buildings appear wavy and a dark or empty area may appear in the center of vision.

The effect of this disease can range from mild vision loss to central blindness. That is, blindness “straight ahead” but with normal peripheral vision from the non-macular part of the retina which is undamaged by the disease.

Two types of Macular Degeneration
Ninety percent of ARMD is of the “atrophic” or “dry” variety. It is characterized by a thinning of the macular tissue and the development of small deposits on the retina called drusen. Dry ARMD develops slowly and usually causes mild visual loss. The main symptom is often a dimming of vision when reading.

The second form of ARMD is called “exudative” or “wet” because of the abnormal growth of new blood vessels under the macula where they leak and eventually create a large blind spot in the central vision. This form of the disease is of much greater threat to vision than the more common dry type.

What are the causes of Macular Degeneration?
Unfortunately, the cause of this eye condition is not fully understood but it is associated with the aging process. As we age, we become more susceptible to numerous degenerative processes like arthritis, heart conditions, cancer, cataracts and macular degeneration. These conditions may be caused by the body’s overproduction of free radicals.

During the metabolic process, oxygen atoms with an extra electron are released. These extra electrons are quite destructive and cause cellular damage, alter DNA, and are thought to be at least partially responsible for many of the degenerative diseases mentioned above. The production of these free radicals is normal during metabolism but the body produces its own “anti-oxidants” to neutralize them.

Some of the vitamins in the food we eat also have anti-oxidant properties. These are vitamins A, C, E and beta-carotene. Unfortunately, smoking, poor nutrition and other lifestyle factors result in the body producing too many free radicals. For this reason, lifestyle factors may contribute to the risk of ARMD.

There is some evidence to suggest that ARMD has a genetic basis, as the condition tends to run in families. The exact nature of this familial tendency, however, has not been clarified. It has been suggested from twin studies that there is a defect in the genes responsible for the integrity and health of the retina.

Exposure to certain types of light may also play a role. Studies performed on fishermen in the Chesapeake Bay suggest that long-term exposure to ultraviolet light from the sun may increase the risk of ARMD and other eye conditions such as the development of cataracts.

It has also been hypothesized that hyperopia or farsightedness may also play a role in the development of the disease. It is thought that the shortening of the eye in hyperopia may cause changes in the membrane below the macula and in its blood vessels.

In the dry form of the disease, some form of inflammation may also be a factor although what causes the inflammation is not known.

Macular Degeneration Treatment?

Although researchers are spending a great deal of time investigating the cause and treatment of ARMD, there is no real cure available. The goal of current treatment efforts is to attempt to stabilize the condition.

For the more severe wet form of the disease, doctors have tried laser photocoagulation. This treatment, however, is not without dangers and is only beneficial in the very early stages of the condition, which is why early detection is so important. This technique involves directing a beam of laser light at the abnormal blood vessels in order to destroy them and prevent their leaking.

Provided that the blood vessels have not grown under the macula, this treatment can be helpful in arresting the progress of the disease. If the blood vessels are already under the macula, the laser may cause scarring and permanent vision loss.

Several new treatments are under development and scientific evaluation. A new type of treatment called photodynamic shows promise. A drug, injected into the arm travels to the affected eye and is then exposed to a non-thermal red light. This light activates the drug to close and seal off the abnormal blood vessels. The entire treatment only takes about 30 minutes and requires no anesthetic.

Treatment using proton beams, which release power at predetermined target site and depth, has also been experimentally tested for treatment of wet-ARMD.

Prevention of Macular Degeneration
Maintaining a healthy lifestyle can play a significant role in the prevention of macular degeneration.

Nutritional Supplements

It is important to keep a healthy diet for optimal eye health, especially as you age. Nutrition plays a significant role in the prevention of age-related eye diseases. Try to eat plenty of green leafy vegetables, such as spinach, as part of your diet.

Vitamins and nutritional supplements should also be included as part of your daily routine. Omega 3s can help prevent age-related macular degeneration. According to AREDS (Age-Related Eye Disease Study) they can slow the process of macular degeneration. Omega 3s are also recommended for people who suffer with dry eye.

Spots & Floaters

Do you occasionally see specks or threadlike strands drifting across your field of vision? Then, when you try to look at them, do they seem to dart away? If so, you’re seeing what eye care practitioners call spots or floaters.

While almost everyone sees a few spots at one time or another, they can occur more frequently and become more noticeable as you grow older. If you notice a sudden change in the number or size of spots, you should contact us right away so you can be sure they are not the result of a more serious problem.

What are spots or floaters?
Spots are small, semi-transparent or cloudy specks or particles within the eye that become noticeable when they fall within the line of sight. They may also appear with flashes of light.

The inner part of your eye is made up of a clear, jelly-like fluid known as the vitreous. As time passes the jelly-like fluid gradually becomes more liquid in nature and cells and structural fibers detach and float around in this jelly, resulting in the floaters that we commonly observe.

When flashes of light occur causing spots to become noticeable, it can be a result of the jelly-like vitreous shrinking and pulling on the retina. This tugging action stimulates the retinal receptor cells to “fire,” causing the perception of light flashes.

Can these spots cause blindness?
Most spots are normal and rarely cause blindness. But spots can indicate more serious problems. If you notice a change in the number and size of spots, a comprehensive eye examination is in order to determine the cause.

On rare occasions, vitreous detachment can cause small tears or holes in the retina. The damaged part of the retina subsequently does not work properly and a blind or blurred spot in vision results. If untreated, retinal tears or holes can continue to worsen and severe vision loss can result if the retina becomes detached.

How are spots diagnosed?
In a comprehensive eye examination, your eyes will be evaluated with special instruments that allow an examination of the health of the inside of your eyes and possible observation of the spots.

This is often done after special drops are put in your eyes to make the pupils larger (called dilation) to allow a larger view of the inside of your eyes. These procedures provide the relevant information to detect spots.

How are spots treated?
While flashes and floaters are normally not serious or treatable, they can be symptoms or signs of either vitreous or retinal detachment. In either of these cases, treatment with lasers and/or surgical intervention may be necessary to preserve your vision. If you notice a sudden increase or change in the number and type of spots and floaters, contact us immediately.

Your Eyes and Vision:
How the Eye Works

 

Our ability to “see” starts when light reflects off an object at which we are looking and enters the eye. As it enters the eye, the light is unfocused. The first step in seeing is to focus the light rays onto the retina, which is the light sensitive layer found inside the eye. Once the light is focused, it stimulates cells to send millions of electrochemical impulses along the optic nerve to the brain. The portion of the brain at the back of the head interprets the impulses, enabling us to see the object.

If my vision is less than optimum, what can I do?
A comprehensive eye examination will identify causes that may affect your ability to see well. We may be able to prescribe glasses, contact lenses or a vision therapy program that will help improve your vision.

If the reduced vision is due to an eye disease, the use of ocular medication or other treatment may be needed. If necessary, referral will be undertaken if an eye disease is found which warrants further investigation.

To keep your eyes healthy and white with clear, crisp vision it is important to schedule an annual exam. With advancements in technology, your annual eye exam is a portal to more than just vision. Today, we can help identify the onset of other ailments as well. Additionally, you can take an active role in the prevention of eye disease by learning more about proper nutrition and how it affects your eyes and vision.
