This consultation, which is part of the anterior segment consultation, focuses specifically on analyzing symptoms and causes of dry eye pathology. A dry eye can result from various factors, both external (humidity, climate) and internal (gland dysfunction, blepharitis, demodex). During this consultation, a thorough analysis of the ocular surface is conducted using tests such as the Schirmer test and Keratograph. These tests measure tear film, NITBUT (Non-Invasive Tear Break-Up Time), tear meniscus height, meibography, and OSDI (Ocular Surface Disease Index) test.
