Floppy eyelid syndrome.

In this review, we define characteristics of floppy eyelid syndrome, as well as related syndromes, such as lax eyelid syndrome. Presenting symptoms, ocular signs, and important clinical examination techniques are described, and associated ocular and systemic conditions, as well as corresponding pathophysiology are discussed. Significant new histopathologic findings in floppy eyelid syndrome and recent surgical developments are summarized. This review provides a critical update of floppy eyelid syndrome and aids the ophthalmologist in new methods of assessment and management.
