Dry eye syndrome

Dry eye syndrome (DES), also known as keratoconjunctivitis sicca (KCS), is the condition of having dry eyes. Other symptoms associated with DES/KCS include irritation, redness, discharge, and easily fatigued eyes. Blurred vision may also occur. Symptoms can be mild and occasional to severe and continuous.

Many risk factors are associated with dry eyes such as aging, frequent flying, smoking, and medications. Health conditions include diabetes, thyroid disease, lupus, rheumatoid arthritis, Sj%C3%B6gren%27s syndrome, and fibromyalgia.

Symptoms
Watery eyes can be a symptom because "dryness on the eye's surface sometimes will over-stimulate production of the watery component of your tears as a protective mechanism. But this "reflex tearing" does not stay on the eye long enough to correct the underlying dry eye condition."

Treatment
A range of treatments are available for dry eyes depending on severity and cause. Artificial tears is usually used for mild cased due to computer use, reading, and schoolwork. Restasis, Xiidra, and steroid eye drops can reduce inflammation. Lacrisert is a solid insert with a preservative-free lubricating agent that slowly liquefies over time which will provide an all-day moistening effect. Punctal plugs are used to help tears remain on the surface of the eye longer. Meibomian gland expression is a procedure to unplug hardened meibum and possibly other substances from the meibomian glands. Warm compresses, which need to maintain a temperature of 108 degrees farenheit for more than 10 minutes twice a day. LipiFlow Thermal Pulsation System (Tear Sicence) is an automated, in office dry eye treatment which combines warm compress therapy and meibomian gland expression. Intense pulsed light treats ocular rosacea. Nutritional supplements containing omega 3 fatty acids can decrease dry eye symptoms.

Some home remedies are to blink more frequently, frequent breaks during computer use, removing eye makeup thoroughly, cleaning eyelids, and wearing quality sunglasses.
