Abstract

Purpose: : The purpose of this study was to determine with spectral-domain OCT the rate of abnormalities in fellow eye of patients with a full-thickness macular hole, and analyzed them to better understand the mechanisms of formation of full-thickness macular hole.

Methods: : Retrospective observational series. 141 fellow eyes of patients with a full-thickness macular hole were examined on spectral-domain OCT. The features of the vitreoretinal interface were classified by SD OCT images, and each layer of the retina was analyzed.

Results: : A perifoveal posterior vitreous detachement was found in 32.6% of patients. In this group, 76 % of patients present abnormalities. They are located mainly at the photoreceptor layer (58%), in particulary between IS/OS junction and retinal piment epithelium, and in 42% of cases, we found foveal deformations, associated in 22% of cases with cysts in the inner retinal layer. Among patients with macular posterior vitreous detachment, 28% of cases have residual deformation of the foveal floor.

Conclusions: : During the perifoveal vitreous detachement, traction of posterior hyaloid seem to be transmitted, probably via Muller cells, to the outer limiting membrane and outer segments of the photoreceptor. These changes sometimes precede the formation of retinal cyst, and suggest different mechanism of formation of macular hole. The incidence of foveal deformations associated with vitreofoveal adhesion and residual foveal deformation after vitreoretinal separation suggest that fellow eyes of macular hole have an abnormally strong vitreofoveal adhesion that can cause foveal structural changes.
