Dry Eye Syndrome
Dry eye syndrome results primarily from compromise to either the quantity or quality of the precorneal tear film. Tears are composed of a mucin layer, water or aqueous layer and an oil layer. Deficiencies in any one of these components may create a tear film which is incapable of properly moistening the eye, resulting in desiccation and symptomatic complaints. Management is aimed at replenishing the eyes' moisture and/or delaying evaporation of the patient's natural tears and removing known predisposing factors if possible. Various types of artificial tears are available over the counter.
