Do You Suffer from Dry Eyes?

Some people do not produce enough tears to keep the eye comfortable. This is known as dry eye.  Tears are produced by two different methods. One method produces tears at a slow, steady rate and is responsible for normal eye lubrication. The other method produces large quantities of tears in response to eye irritation or emotions.


Tears that lubricate are constantly produced by a healthy eye. Excessive tears occur when the eye is irritated by a foreign body or when a person cries.

What are the symptoms of dry eye?
  • Stinging or burning eyes;
  • Scratchiness;
  • Stringy mucus in or around the eyes;
  • Eye irritation from smoke or wind;
  • Excess tearing;
  • Difficulty wearing contact lenses.
A film of tears, spread over the eye by a blink, makes the surface of the eye smooth and clear. Without our tear film, good vision would not be possible.

The tear film consists of three layers:
  • An oily layer - produced by the meibomian glands, forms the outermost surface of the tear film. Its main purpose is to smooth the tear surface and reduce evaporation of tears.
  • A watery layer - this layer makes up most of what we ordinarily think of as tears. This layer, produced by the lacrimal gland, cleanses the eye and washes away foreign particles or irritants.
  • A layer of mucus - produced by the conjunctiva. Mucus allows the watery layer to spread evenly over the surface of the eye and helps the eye remain wet. Without mucus, tears would not adhere to the eye.
What causes dry eye?

Tear production normally decreases as we age. Although dry eye can occur in both men and women at any age, women are most often affected. This is especially true after menopause.

Dry eye can also be associated with arthritis and accompanied by a dry mouth. People with dry eyes, dry mouth and arthritis are said to have Sjogren's syndrome.

A wide variety of common medications-prescription and over-the-counter-can cause dry eye by reducing tear secretion. Be sure to tell your ophthalmologist the names of all the medications you are taking, especially if you are using:
  • Diuretics;
  • Betablockers;
  • Antihistamines;
  • Sleeping pills;
  • Medications for “nerves”;
  • Pain relievers.
Since these medications are often necessary, the dry eye condition may have to be tolerated or treated with “artificial tears”.

People with dry eye are often more prone to the toxic side effects of eye medications, including artificial tears. For example, the preservatives in certain eye drops and artificial tear preparations can irritate the eye. Special preservative-free artificial tears may be required.

Anything that may cause dryness, such as an overly warm room, hair dryers, or wind, should be avoided by a person with dry eye.  Smoking is especially bothersome.

Some people with dry eye complain of “scratchy eyes” when they wake up.  This symptom can be treated by using an artificial tear ointment at bedtime.  Use the smallest amount of ointment necessary for comfort, since the ointment can cause your vision to blur temporarily.

If you feel you suffer from dry eye and artificial tears are not helping please call our office, we are one of the only Accredited Dry Eye Centers in the area. Schedule your appointment to evaluate the many options available for treatment.

Cataract Symptoms & Clearing the Blur

Image
More than 20 million Americans over the age of 40 have cataracts and nearly three million patients have cataract surgery in the US annually.  Technological advances have made cataract surgery safer, more comfortable and more effective. A cataract is a gradual clouding of the clear lens in the eye, the part that focuses light and produces clear images.  As old cells die they become trapped.  As time passes, more cells die and accumulate causing the lens to cloud, making vision blurred and dim.  Cataracts form slowly and painlessly, but can eventually lead to blindness. Cataracts can be caused by metabolic diseases such as diabetes, an injury to the eye, medications, long-term exposure to the sun, eye surgery, congenital defects or aging. Please refer patients if they are experiencing any of the following: Blurry vision, with no pain Glare, or sensitivity to light Double vision in one eye The need to read with brighter light Poor night vision Dull ...

Dry Eye Education

There are two main forms of Dry Eye disease. Are you treating the right one? Tears are necessary for your overall eye health. Dry Eye occurs when the eyes do not produce sufficient tears or the tears evaporate too quickly. Without proper treatment, inadequate tears can make daily activities frustrating, affecting your personal and professional life, from reading to watching TV, to driving or working on the computer.  The most common form of Dry Eye is Evaporative Dry Eye, which affects 9 out of 10 (86%) Dry Eye cases. 1 This form results from a shortage of oil in your tears caused by a blockage in your eyelid (Meibomian) glands, leading tears to evaporate faster than normal. This lack of tear oil is often referred to as Meibomian Gland Dysfunction (MGD).   Now, with the breakthrough LipiFlow® technology, it’s possible to directly treat the root cause of Evaporative Dry Eye. If you think you suffer from  Meibomian Gland Dysfunction (MGD) call us tod...
