To determine the rate of successful macular hole closure with 1-day postoperative prone positioning
Multicentre review of all consecutive cases of stage 3 and 4 macular hole surgery performed during a 15-month period employing 1-day postoperative face-down positioning regimen. Cataract surgery was not routinely combined with macular hole surgery. Internal limiting membrane peeling was employed in all but seven eyes. Either SF6 or C3F8 gas tamponade was used. The primary outcome assessed was the rate of hole closure.
56 eyes of 53 patients were identified. 79% of eyes had stage 3 macular holes, and 39 of 56 (70%) eyes were phakic at the time of surgery. The mean preoperative logMAR vision was 0.74 (approximately 20/100 Snellen) and mean postoperative logMAR vision was 0.41 ( approximately 20/50 Snellen) with a mean follow-up period of 5.2 months. Macular hole closure was achieved in 52 eyes (93%) with one operation.
Sustained postoperative face-down positioning may not be necessary for successful macular hole closure, since 93% of eyes achieved hole closure with prone positioning for only 1 day.
确定术后1天俯卧位治疗黄斑裂孔成功闭合的比率
对15个月期间采用术后1天面朝下体位治疗方案进行的所有连续性3期和4期黄斑裂孔手术病例进行多中心回顾。白内障手术未常规与黄斑裂孔手术联合进行。除7只眼外,所有眼均采用内界膜剥除术。使用了SF6或C3F8气体填塞。评估的主要结果是裂孔闭合率。
共确定了53例患者的56只眼。79%的眼为3期黄斑裂孔,56只眼中的39只(70%)在手术时为有晶状体眼。术前平均logMAR视力为0.74(约20/100 Snellen),术后平均logMAR视力为0.41(约20/50 Snellen),平均随访期为5.2个月。52只眼(93%)一次手术即实现黄斑裂孔闭合。
对于黄斑裂孔的成功闭合,术后持续俯卧位可能并非必要,因为93%的眼仅俯卧位1天即实现裂孔闭合。
