To demonstrate the potential for visual recovery after surgery for early foveal involvement by progressive degenerative retinoschisis.
Surgical case report.
A 79-year-old woman was monitored over 4 years for degenerative retinoschisis in the inferotemporal periphery of both eyes. Over the course of follow-up, visual acuity in the left eye decreased from 20/40 to 20/100, concurrent with extension of the schisis cavity into the macula. Macular involvement was confirmed on optical coherence tomography imaging, and there was no rhegmatogenous retinal detachment. The patient elected to undergo 25-gauge pars plana vitrectomy and drainage of the schisis cavity. Eleven weeks after surgery, the macula remained attached, and the uncorrected visual acuity was 20/30. Fundus examination and spectral domain optical coherence tomography confirmed ongoing resolution of the macula-involving retinoschisis.
Bullous degenerative retinoschisis is believed to result in an absolute scotoma that is not surgically correctable. Our patient's excellent visual recovery suggests that the synaptic integrity of the macular outer plexiform layer can be preserved and a permanent scotoma avoided if early macular involvement by progressive degenerative retinoschisis is surgically repaired.
展示手术治疗早期黄斑受累的进行性变性性格子状视网膜劈裂的潜在视力恢复能力。
手术病例报告。
一名 79 岁女性因双眼颞下周边退行性格子状视网膜劈裂接受了 4 年的监测。在随访过程中,左眼视力从 20/40 下降到 20/100,同时劈裂腔扩展到黄斑。光学相干断层扫描成像证实黄斑受累,且无孔源性视网膜脱离。患者选择接受 25G 经睫状体平坦部玻璃体切除术和劈裂腔引流。术后 11 周,黄斑仍在位,未矫正视力为 20/30。眼底检查和频域光学相干断层扫描证实黄斑受累的格子状视网膜劈裂持续缓解。
认为大疱性退行性格子状视网膜劈裂会导致不可手术矫正的绝对暗点。我们的患者视力恢复良好,这表明如果早期进行性退行性格子状视网膜劈裂累及黄斑并进行手术修复,可以保留黄斑外丛状层的突触完整性并避免永久性暗点。
