subject: Some Causes Of Dry Eye Syndrome [print this page] Keratoconjunctvitis sicca is commonly known to lay people as dry eye syndrome. This is a condition where either not enough tears are produced by the tear ducts or the tears that are produced are of an inferior quality. High quality tears are essential for lubrication and to protect from infection or inflammation. There are several underlying causes that may be linked to experiencing the condition.
The first underlying cause is age. Ocular dryness is a natural part of aging. By the late sixties, more people than not have a reduction of tear production. Adding over the counter drops in the morning and evening can alleviate dryness, redness and itchiness.
Gender is also a factor since women tend to experience hormonal fluctuations more frequently than adult men, though it is possible in both genders. Events such as menopause or pregnancy can both contribute. The changes to estrogen levels may cause dryness and itch that can be alleviated with over the counter drops.
Some medications reduce the amount of tears produced naturally as a side effect. Cold medicines often cause this side effect, but it is easily missed when people are already suffering from a head cold. Blood pressure medications and antidepressants have also been known to contribute to drying eyes.
Certain medical conditions have also been noted as an underlying cause. Thyroid changes, diabetes, and rheumatoid arthritis are all potential suspects. They disrupt normal hormonal cycle and can cause the onset of symptoms. This is a reason to mention any ocular dryness to your doctor. It may be a sign of another condition.
Another area that can be a cause is the eyelid. Its purpose is to protect and spread tears to lubricate the eyeball and keep it clear. Inflammation or infection of the eyelid can disrupt this process. Check them for any redness, swelling, or sensitivity to the touch.
There are external conditions that can cause dryness and discomfort as well. Living in an arid climate is one. Extensive time at a computer monitor is another. Running a humidifier to add moisture to the air is one solution. Blinking frequently while reading on a computer is another good suggestion. Some people experience symptoms from air conditioning. For mild discomfort, over the counter drops might be a good suggestions. If your symptoms worsen, it may be a good idea to mention dry eye syndrome to your doctor at your next check up.
