To compare the effects of scleral buckling using wide-angle viewing systems (WAVS) with that using indirect ophthalmoscope for the treatment of rhegmatogenous retinal detachment.
The study was a retrospective analyses of the medical records of 94 eyes (94 patients) with rhegmatogenous retinal detachment. Among them, 47 eyes underwent scleral buckling using WAVS with endoilluminator (Group W), and 47 eyes underwent scleral buckling using indirect ophthalmoscope (Group I). Surgical durations, primary success rate, best-corrected visual acuities (BCVA), delayed subretinal fluid absorptions and surgical complications were compared between the two groups.
At baseline, there were no statistical differences between the two groups in patient's age (P=0.997), gender (P=0.853), symptom duration (P=0.216), BCVA (P=0.389), refractive error (P=0.167), intraocular pressure (P=0.595), the number of retinal breaks (P=0.832), the extent of retinal detachment (P=0.246), subretinal demarcation line (P=0.801), and macular detachment (P=0.811). The follow-up period was 12mo. The surgical durations in Group W (with or without encircling buckling) were significant shorter than those in Group I (P<0.001 respectively). The primary success rate was 94.27% in Group W, which was similar to that in Group I (92.38%, P = 0.931). The BCVA in Group W was better than that in Group I (P<0.001) at 1-month follow-up visit. However, there were no significant differences between the two groups at 3-month (P=0.221), 6-month (P=0.674), and 12-month (P=0.363) follow-up visits respectively. Delayed subretinal fluid absorptions were more common in Group I than in Group W at 1-month (P=0.045) follow-up visit, but there were no significant differences between the two groups at 3-month (P=0.111), 6-month (P=1.000) and 12-month follow-up visits respectively.
Scleral buckling using WAVS can be an alternative choose for rhegmatogenous retinal detachment.
比较使用广角观察系统（WAVS）与间接检眼镜进行巩膜扣带术治疗孔源性视网膜脱离的效果。
本研究对94例（94只眼）孔源性视网膜脱离患者的病历进行回顾性分析。其中，47只眼使用带眼内照明器的WAVS进行巩膜扣带术（W组），47只眼使用间接检眼镜进行巩膜扣带术（I组）。比较两组的手术时间、一次成功率、最佳矫正视力（BCVA）、视网膜下液延迟吸收情况及手术并发症。
基线时，两组患者的年龄（P = 0.997）、性别（P = 0.853）、症状持续时间（P = 0.216）、BCVA（P = 0.389）、屈光不正（P = 0.167）、眼压（P = 0.595）、视网膜裂孔数量（P = 0.832）、视网膜脱离范围（P = 0.246）、视网膜下分界线（P = 0.801）及黄斑脱离情况（P = 0.811）均无统计学差异。随访期为12个月。W组（无论有无环扎）的手术时间均显著短于I组（P均<0.001）。W组的一次成功率为94.27%，与I组（92.38%，P = 0.931）相似。随访1个月时，W组的BCVA优于I组（P<0.001）。然而，在3个月（P = 0.221）、6个月（P = 0.674）和12个月（P = 0.363）随访时，两组之间无显著差异。随访1个月时，I组视网膜下液延迟吸收比W组更常见（P = 0.045），但在3个月（P = 0.111）、6个月（P = 1.000）和12个月随访时，两组之间无显著差异。
使用WAVS进行巩膜扣带术可作为孔源性视网膜脱离的一种替代选择。
