Patients and methods
In a prospective study of nine highly myopic eyes with posterior staphyloma in seven consecutive patients (five women and two men), we performed vitreous surgery at Gunma University Hospital between May 1999 and July 2002. Each patient reported a decrease in visual acuity associated with central metamorphopsia in the affected eye a few months before OCT established the diagnosis. The study was approved by ethics committee at Gunma University Hospital and complied with the guidelines of the
Results
Preoperative slit-lamp biomicroscopy showed PVD with a floating Weiss ring in six of nine eyes (Table 1). Three eyes showed no evidence of PVD. OCT demonstrated a slightly detached vitreous cortex in the perifoveal area, but it was attached to the fovea in three eyes (cases 4, 5, and 7). Two of the three eyes had no PVD, but the other had PVD on biomicroscopy. Preoperative OCT failed to detect the presence of a preretinal vitreous cortex in the remaining six eyes. Although six of the nine eyes
Discussion
We performed vitreous surgery in nine eyes of seven cases with foveal detachment and retinoschisis and obtained foveal reattachment and resolution of retinoschisis in eight of nine eyes. All nine eyes had a symptomatic decrease in vision within a few months before OCT established the diagnosis. Preoperative OCT showed a foveal retinal detachment and foveal retinoschisis in all nine eyes. During the preoperative period, the foveal retinal detachment enlarged in one eye (right eye of case 4) (Fig
