目的：评估治疗孔源性视网膜脱离(RRD)的巩膜扣带术中使用吊顶灯照明系统的优势。

方法：在这一对照、回顾性研究中，72例72眼于密涅瓦医院接受巩膜扣带术治疗的RRD患者分为两组。A组在吊顶灯照明下行巩膜扣带术，B组进行常规巩膜扣带术。两组均于术前、术后1、3、7、14、30、90和180d进行随访。指标包括其它手术操作、最佳框架眼镜矫正视力(BSVA)、手术时间、视网膜裂孔再次出现进行了分析和比较。

结果：术后6mo，两组BSVA均较术前显著改善(P<0.01)。两组再次出现视网膜裂孔的比例未见明显差异，但A组手术时间较B组明显缩短。

结论：通过我们观察得出结果，使用巩膜扣带术治疗RRD时，吊顶灯照明系统是一个有价值的工具，即使这些结果需要在更大人群中进一步研究证明。

METHODS: In this comparative, retrospective study, data of 72 eyes of 72 patients undergoing SB for RRD at Minerva Hospital(Santa Maria Capua Vetere, Italy), divided in 2 groups of 36 eyes each were collected. In one group(group A)eyes underwent SB with chandelier, in the other one(group B)eyes underwent SB without using chandelier illumination system. Every eye of both groups was checked before surgery and at 1, 3, 7, 14, 30, 90 and 180d follow up. Parameters such as additional procedures, best spectacles visual acuity(BSVA)(measured with Snellen Lines as decimal fraction), surgical time and retinal breaks recurrences had been analyzed before and after surgery and statistical comparison have been run between two groups.

RESULTS: A significant(P<0.01)improvement in BSVA was observed at 6mo follow up in both groups; comparing groups A and B, no significant clinical differences was found in recurrences rate whereas mean surgical time in group A was statistically lower than the group B ones.

CONCLUSION: According to results observed, even if they need to be confirmed in further studies with larger population, chandelier illumination system could be considered a valuable tool for SB surgery in eyes affected by RRD.
