目的 观察表面麻醉下行 2 5 G经结膜无缝合玻璃体视网膜手术的疗效、适应证和并发症。 方法 回顾分析 2 2例爱尔卡因滴眼液表面麻醉下采用 2 5 G经结膜无缝合玻璃体切割手术系统 (TSV2 5 G)行玻璃体视网膜手术患者的临床及随访资料。 2 2例患者均为单眼患病接受治疗。其中特发性黄斑裂孔 10只眼 ,特发性黄斑前膜 6只眼 ,玻璃体黄斑牵引综合征 4只眼 ,视网膜分支静脉阻塞玻璃体积血 2只眼。根据病情行视网膜前膜、黄斑前膜和 (或 )内界膜剥离 ,气液交换和全氟丙烷 (C3F8)气体眼内充填。手术后随访 1～ 11个月 ,平均随访时间 6 .4个月。主要观察分析手术中的镇痛效果、患者合作程度、手术效果以及手术中和手术后并发症。 结果 所有手术眼均可在表面麻醉下顺利完成手术操作。手术时间 2 0～ 2 5 min,平均手术时间约 2 2 min。手术中患者无特别不适 ,能配合手术 ;手术后 2 d内手术创口结膜轻度水肿 ,7d后已无明显痕迹。1个月时仅在巩膜表面见一浅的色素沉着点。手术后一过性眼压升高 2只眼 ,晶状体后囊羽毛状混浊 5只眼 ,玻璃体积血 1只眼 ,结膜下气泡 2只眼。未发生感染性眼内炎、医源性视网膜裂孔及视网膜脱离、脉络膜脱离以及其他与切口相关的并发症。特发性黄斑裂孔患者 9只眼裂孔闭合 ,1只眼裂孔?
Objective To observe the curative effect, indications and complication of 20G surgical closure of vitreoretinal surgery by surface anesthesia. Methods The clinical data and follow-up data of 20 patients undergoing vitreoretinal surgery with 25 Gy transconjunctival suture combined with vitrectomy (TSV2 5 G) under surface anesthesia were retrospectively analyzed. 2 2 patients were treated for monocular disease. Including 10 cases of idiopathic macular hole, 6 cases of idiopathic macular degeneration, 4 cases of vitreoretinal traction syndrome, 2 cases of retinal branch vein occlusion vitreous hemorrhage. According to the condition of retinal pre-membrane, pre-macular and (or) endometrial stripping, gas-liquid exchange and perfluorinated propane (C3F8) gas intraocular filling. The patients were followed up for 1 to 11 months and the average follow-up time was 6.4 months. The main observation and analysis of analgesic effect in surgery, patient cooperation, surgical results and intraoperative and postoperative complications. Results All surgical eyes under the surface anesthesia successfully completed the operation. Surgery time 20 ~ 25 min, the average operation time of about 2 2 min. The patients had no special discomfort during the operation and could cooperate with the operation. There was no obvious signs of conjunctival edema within 2 days after operation. At 1 month, the surface of the sclera only see a shallow pigmentation point. Postoperative transient elevated intraocular pressure in 2 eyes, posterior capsular feathery opacity in 5 eyes, vitreous hemorrhage in 1 eye and conjunctival air bubble in 2 eyes. Infective endophthalmitis, iatrogenic retinal tears and retinal detachment, choroidal detachment, and other incision-related complications were not present. Nine patients with idiopathic macular hole closed the hole, a hole in the eye?
