The significant increase in the volume of dry eye patients has introduced more dry eye tests today than previously seen. Eye care professionals may wish to approach the tests by first understanding the likely causes of dry eye: MGD/Evaporative Dry Eye; Aqueous Deficient Dry Eye; Ocular Allergy; and Autoimmune disease.
86% of dry eye patients have Meibomian Gland Dysfunction.55 As a primary cause of dry eye, it is important to test for MGD to direct treatment appropriately. The core tests for MGD include measuring lipid layer thickness and partial blinks; utilizing a standardized, repeatable evaluation of meibomian glands; Dynamic Meibomian Imaging™ (DMI™) and by assessing lid closure by looking at partial blink (LipiView®), lagophthalmos (staining), and/or inadequate lid seal (KB light test). These tests provide data to better understand the meibomian function and structure. Other core tests may be needed to identify the cause and direct the treatment for aqueous deficient dry eye, ocular allergy and autoimmune disease.
These core tests and other supporting tests enable the savvy eye care professional in managing Meibomian Gland Dysfunction and other types of dry eye.
