Pigmentary changes in acquired retinoschisis

We reviewed retrospectively the records of patients referred for retinal examination and found 375 eyes (233 patients) with acquired retinoschisis. Of the 375 eyes, 85 had outer layer retinal breaks, 27 had retinal detachments, and 29 had pigmentary lines. Twenty-five of the 29 pigmentary lines (86.2%) demarcated either retinal detachment or outer retinal layer breaks.
