Dry eye is a condition that occurs when a person's eyes have insufficient or poorly made tears to properly lubricate the eyes and the eyelid. Without the natural lubrication and cleansing of tears, a sufferer may experience a feeling of grit or debris in the eyes, blurred vision, tired eyes and sensitivity to light. Their eyes may appear reddened and inflamed. In extreme cases, chronic dry eye can result in increased eye infections and scarring of the cornea
Up to 5% of Americans complain of some form of dry eye. Individuals who wear contact lenses or have undergone LASIK or other types of refractive surgery are typical sufferers. The condition is more common in women than men, and is more common and severe in older people.
Many diseases, disorders of the eye and side effects of medication can cause dry eye. Essentially, dry eye results under conditions in which too few tears are produced or evaporation of tears takes place too quickly. Quality tears are not simply salt water, but are made of three different substances -- mucin, water and oil -- designed to work together in proper proportions.
The mucous layer lies just above the eye surface and helps the tear "water" spread evenly across the entire eye surface quickly and with each blink of the eyelid. The oil portion floats above the tear layer and not only helps lubricate blinking, but also actively slows down the rate of evaporation of tears from the eyes. Any interruption in these layers or their proportions can result in dry eye.
Dr. Jackman will discuss treatment options with you that depend upon how seriously the problem is affecting your life and whether complications are likely to occur. Treatment may consist of a combination of over-the-counter "tear drops," oral prescription medication to increase your tear production or even omega-3 fatty acid nutritional supplements. Sometimes surgery can help. One type of surgery -- in temporary or permanent form -- plugs up the tear ducts so that tears cannot drain back into the body.
Ask your doctor how to best begin treating your dry eye condition.
