Causes of dry eye can be categorized as either aqueous deficient (lacrimal gland related), evaporative (Meibomian gland related) or a combination of both. Allergy can also play a role in exacerbating dry eye and should be identified and treated appropriately, in conjunction with dry eye treatment if required. Within each category of dry eye there are also intrinsic and extrinsic causes which need to be identified to provide best care and management. Lemp and colleagues showed in their 2012 study population that 50% of patients were categorised as having an aqueous deficiency and 86% an evaporative component to their dry eye disease. Inflammation played a significant role in both of these categories, and therefore diagnosing and managing inflammation will almost always play a role in any dry eye disease management protocol.
