Meibomian gland dysfunction: a clinical scheme for description, diagnosis, classification, and grading

Ocul Surf. 2003 Jul;1(3):107-26. doi: 10.1016/s1542-0124(12)70139-8.


Although meibomian gland disease (MGD) is one of the most common disorders encountered in ophthalmic practice, there has been no descriptive system consistently accepted to clinically characterize the anatomical and correlative biochemical alterations that occur in this condition. The purpose of this review is to synthesize a clinical description of meibomian gland disease and to provide a scheme for diagnosis, classification, and quantification that will be of value in the clinical setting and in the conduct of clinical trials.
