In a series of 72 rhegmatogenous retinal detachments treated by scleral buckling procedure with or without intraocular gas injection, 5 patients showed a subsequent inferior retinal detachment in the operated eye early in the postoperative period. All 5 eyes had been injected with air or sulfur hexafluoride intraoperatively or postoperatively, and had vitreoretinal adhesions such as lattice degeneration in the inferior equatorial fundus. To investigate the factors involved in the development of the new inferior retinal detachment, the data on the 72 eyes of retinal detachment were analyzed. Intraocular gas injection, inferior vitreoretinal adhesion, and the volume of injected gas were the significantly associated factors (P < 0.05). It was suggested the intraocular gas bubble could produce traction on the site of inferior vitreoretinal adhesion, leading to new inferior retinal detachment.
在一系列72例采用巩膜扣带术治疗的孔源性视网膜脱离患者中，无论是否联合眼内注气，有5例患者在术后早期术眼出现了下方视网膜脱离。所有这5只眼均在术中或术后注入了空气或六氟化硫，并且在赤道部下方眼底存在玻璃体视网膜粘连，如格子样变性。为了研究新出现的下方视网膜脱离的发生相关因素，对这72只视网膜脱离患眼的数据进行了分析。眼内注气、下方玻璃体视网膜粘连以及注入气体的量是显著相关因素（P<0.05）。提示眼内气泡可在下方玻璃体视网膜粘连部位产生牵拉，导致新的下方视网膜脱离。
