Surgical management of retinal fold after 23-Gauge pars plana vitrectomy retinopexy

Abstract The authors report a case of retinal fold after retinal detachment repair performed using 23-gauge pars plana vitrectomy technic (PPV). The fundus photography and optical coherence tomography (OCT) showed a posterior retinal fold with the retina periphery attached. The patient’s best corrected visual acuity (BCVA) was 20/200 with severe metamorphopsia. A 25-gauge PPV, subretinal balanced saline solution (BSS) injection using a 25-39-gauge cannula, and gas-fluid exchange were performed. The patient’s BCVA improved significantly after treatment. The retinal fold observed is not a frequent complication and can be managed with PPV, subretinal BSS injection and fluid-air exchange.摘要 作者报告1例采用23号经睫状体平坦部玻璃体切割术（23-gauge pars plana vitrectomy, PPV）行视网膜脱离修复术后并发视网膜皱褶的病例。眼底照相与光学相干断层扫描（optical coherence tomography, OCT）检查显示，患者存在后极部视网膜皱褶，且视网膜周边部已复位。患者最佳矫正视力（best corrected visual acuity, BCVA）为20/200，伴严重视物变形。术者为其实施了25号经睫状体平坦部玻璃体切割术、采用25-39号套管针行视网膜下平衡盐溶液（balanced saline solution, BSS）注射以及气液交换治疗。术后患者最佳矫正视力显著改善。本次观察到的视网膜皱褶并非常见并发症，可通过经睫状体平坦部玻璃体切割术、视网膜下BSS注射及液气交换进行处理。
