Diagnostics of dry eye

Dry eye is a multi-factorial disease of tears and ocular surface resulting in symptoms of discomforts, vision disabilities, unstable tear film and possible damage to the ocular surface. The final diagnosis of dry eye results from collecting various data obtained in the course of several diagnostic procedures. DRY EYE - DIAGNOSTIC METHODS: Diagnosis of dry eye involves performing a series of clinical methods and laboratory tests. This paper presents some of the procedures used in the diagnosis of dry eye. Biomicroscopy of the eye with objective tests to check the tear film (Schirmer I, rose bengal, time break up precorneal tear film), verification of corneal sensitivity and impression cytology of the conjunctiva, are the optimum dry eye diagnostic routine procedures.
