Macular Hole Formation after Pars Plana Vitrectomy for the Treatment of Valsalva Retinopathy: A Case Report

초록

We report a case of complete surgical resolution of Valsalva retinopathy that manifested as a premacularhemorrhage involving a membrane followed by a macular hole (MH) resulting from the first vitrectomy. A 20-year-old female patient was referred to our hospital due to sudden vision loss in the left eye. Herbest-corrected visual acuity (BCVA) in the left eye was hand motion. Fundus photographs and opticalcoherence tomography (OCT) revealed a premacular hemorrhage. Nine weeks later, the BCVA in the lefteye had returned to 20 / 100 and the premacular hemorrhage had completely resolved, but residual subinternallimiting membrane deposits and a preretinal membrane were present. The preretinal membranewas removed by core vitrectomy and preretinal membrane peeling, but the foveal deposits could not beexcised. Two weeks after the first vitrectomy, the deposits resolved spontaneously, but a full-thickness MHwas present. Six months after a second vitrectomy with fluid-gas exchange, the BCVA in the left eye hadimproved to 20 / 25 and OCT showed that the MH had closed. This case illustrates the possibility of MHformation following vitrectomy for Valsalva retinopathy.
