A 72-year-old woman had vitreous surgery for epiretinal membrane using the 25-gauge vitrectomy system. During the removal of the cannula at the end of the surgery, half of its tip was noted to be missing. The following day, a severe choroidal detachment associated with a hypotony was found. A second surgery was performed, including drainage of suprachoroidal hemorrhage and choroidal fluid and the removal of the tip of the 25-gauge cannula stuck inside the sclerotomy. The retained cannula tip might have acted as a channel allowing vitreous fluid into the suprachoroidal space, resulting in choroidal detachment, hemorrhage, and hypotony.
一名72岁女性使用25G玻璃体切割系统进行了视网膜前膜玻璃体手术。手术结束时拔除套管时，发现其尖端一半缺失。第二天，发现严重的脉络膜脱离并伴有低眼压。进行了第二次手术，包括引流脉络膜上腔出血和脉络膜液，以及取出卡在巩膜切开处的25G套管尖端。残留的套管尖端可能起到了一个通道的作用，使玻璃体液进入脉络膜上腔，导致脉络膜脱离、出血和低眼压。
