Floppy eyelid syndrome: stretching the limits.
Floppy eyelid syndrome is a distressing condition that can cause significant morbidity and vision loss. Many systemic and ocular associations have been proposed, most notably keratoconus and obstructive sleep apnea-hypopnea syndrome. Although conservative treatments can sometimes be effective, a wide variety of surgical treatments to tighten the upper eyelid have been described. The underlying pathogenesis remains elusive, although progress has been made in the identification of extracellular matrix changes in the tarsal plate. This systematic review discusses the issues surrounding ambiguities in the definition of floppy eyelid syndrome as well as what is currently known about its clinical features, ocular and systemic associations, pathological changes, and proposed theories of pathogenesis. In addition a critical discussion of the proposed surgical treatments and their reported success rates and follow-up times is provided.
