2006-09: The putative role of keratoconjunctivitis sicca in the development of blepharoptosis.
Blepharoptosis (drooping eyelid) can cause loss of visual function. Because surgical correction of the upper eyelid has been shown to significantly improve the visual field, ptosis surgery has become a widely accepted and frequently performed intervention. It is conjectured that prolonged incremental friction between (dry) eye surface and upper eyelid may lead to some degree of mechanical dysintegration of the aponeurosis. Therefore, a dry eye may form an additional risk factor for aponeurotic ptosis. The objective of this study is to determine whether a correlation can be demonstrated between dry eye and ptosis.
