[Macular folds after surgical repair of retinal detachment]

Abstract

The incidence of retinal folds following surgical repair of retinal detachment is underestimated. The extent of retinal folds is variable and can include the complete retina with all layers and an apposition of the photoreceptor outer segments or only partially affect the outer or inner retinal layers. While complete folds can be relatively easily detected by clinical examination, discrete partial folds are sometimes difficult to assess biomicroscopically. In these cases, high-resolution optical coherence tomography (OCT) plays an important role as a tool for differential diagnosis. If macular translocation occurs during the formation of folds, mostly in associated with inferior retinal folds, patients often complain of binocular double vision. A significant reduction of visual acuity and metamorphopsia occur in cases where the folding involves the fovea. In general, retinal folds tend to resolve spontaneously over a prolonged period of follow-up of several months; however, in cases of foveal involvement and corresponding symptoms, a surgical revision can be indicated, although the surgical procedure is not standardized.
