Dry eye syndrome

Although it is often pointed out, tear deficiency is rarely the cause of dry eye syndrome. It is often a dysfunction of the Meibomius glands, which are responsible for the production of the lipidic film whose role is to prevent the evaporation of tears. Defined in 2007, dry eye is "a chronic multifactorial disease affecting the tears and the surface of the eye, resulting in symptoms of discomfort, visual disturbance and tear film instability". It manifests itself by various symptoms that can lead to vision problems: dry, red eyes, a sensation of grains of sand, burning, tearing, itching, etc.

Currently, the treatments available to patients are eyelid hygiene and artificial tears or lubricating eye drops.
