Dryness Symptoms, Diagnostic Protocol and Therapeutic Management: A Report on 1,200 Patients

PURPOSE: To report the diagnostic and therapeutic data obtained from 1,200 patients suffering from dry eye symptoms not due to Sjögren's syndrome or other auto-immune diseases. METHODS: Schirmer test I, ferning test, breakup time, vital dye staining, brush and imprint cytology were performed; data were grouped into diagnostic profiles, and the therapy was prescribed according to these. RESULTS: Eight diagnostic profiles were identified. Dry eye was diagnosed in 57.1% of patients; the remaining 42.9% were found to suffer from eye discomfort or conjunctivitis of different aetiologies. CONCLUSIONS: Subjective symptoms of dryness can hide diseases other than dry eye; combined clinical and laboratory tests are requested to make a diagnosis. Our experience indicates that a therapy prescribed on the basis of diagnostic profiles provides relief in 79.1% of cases.
