2018-32: Prevalence of vitreoschisis-induced vitreous cortex remnants over the peripheral retina
Vitreoschisis is an anomalous type of (spontaneous or iatrogenic) posterior vitreous detachment in which the posterior vitreous cortex is split and the outermost layer of the vitreous cortex may remain attached to the retina. This layer can exert traction on the retina. Several studies have suggested that vitreoschisis attached to the macula might be implicated in the pathology of macular pucker and macular hole. We hypothesized that the presence and unremoved vitreoschisis-induced vitreous cortex remnants (VCR) over the retinal periphery may lead to an increased risk of retinal (re-)detachments after vitrectomy. However, the prevalence of peripheral VCR in patients is not known. This study will assess the prevalence of peripheral VCR in patients undergoing vitrectomy for primary rhegmatogenous retinal detachment (RD), macular pucker (MP) and macular hole (MH).
