Abstract Purpose:To report a case of moderate myopia who showed bilateral retinoschisis and unilateral retinal detachment.

Case:A 71-year-old woman presented with impaired vision in her right eye since one month before.

Findings and Clinical Course:Visual acuity was 0.4 in the right eye when corrected by −3.25 diopters, and was 0.7 in the left eye when corrected by −5.0 diopters. Length of ocular axis was 25.18 mm in the right eye and 25.46 mm in the left. The fundus showed tigroid appearance. Optical coherence tomography(OCT)showed retinal detachment in the right eye, involving the macula and extending over the superior vascular arcade. There was no sign of retinochoroidal degeration or inflammation. The left eye showed normal findings in the macular area. Fluorescein fundus angiography showed normal findings. OCT covering a wider area showed retinoschisis superior to the disc in both eyes. Retinal detachment and the area of retinoschisis were contiguous in the right eye. Over one year later, an outer break in the retinoschisis was detected by OCT suggesting that the retinal detachment was due to pathologic myopia. The right eye received vitreous surgery with peeling of internal limiting membrane and gas tamponade. The posterior vitreous was firmly attached to the retina. Retinal detachment disappeared with improved visual acuity to 0.8.

Conclusion:Traction around the optic disc appears to have caused retinoschisis and retinal detachment. Vitreous surgery was effective in this case.
