Morphological changes in the optic disc after vitrectomy and fluid-air exchange.

Background: Although many investigators have previously reported various ocular complications induced by vitrectomy, little is known about post-operative morphological changes in the optic disc. The purpose of this study is to evaluate the effect of vitrectomy and fluid-air (F-A) exchange on the post-operative morphology of the optic disc.

Methods: We examined 31 eyes that had undergone vitrectomy for macular holes (22 eyes) or epiretinal membranes (9 eyes).
