The differential diagnosis of red eye: a survey of medical practitioners from Eastern Europe and the Middle East.

A survey amongst ophthalmologists and general medical practitioners from nine countries in Eastern Europe and the Middle East was conducted to estimate the percentage of patients presenting with a red eye and to examine differential diagnosis and treatment. Practitioners recorded brief details of every patient seen and detailed information concerning signs and symptoms, differential diagnosis and treatment for all patients presenting with a red eye during 20 consecutive days in the period between May and September 2004. Red eyes accounted for approximately 15% of consultations with ophthalmologists and almost 6% with general medical practitioners. Allergic conjunctivitis was the most common diagnosis (35%), followed by dry eye (25%) and bacterial conjunctivitis (24%). General medical practitioners were far more likely to prescribe a combination topical antibiotic and steroid preparation than ophthalmologists. This survey illustrates that red eye remains a very important problem for both ophthalmologists and general medical practitioners. Identification of dry eye as a common cause of red eye symptoms and more appropriate treatment of dry eye, allergic conjunctivitis and viral conjunctivitis are key messages to emerge.
