Two unusual cases of rhegmatogenous retinal detachment following contusion to the eyeball showed retinal tears at the posterior fundus close to the optic disc and the large retinal blood vessels. In both cases, the tears were not detected immediately after the injury due to a coexisting vitreous hemorrhage. Both patients were successfully treated by pars plana vitrectomy, air-fluid exchange, and endolaser photocoagulation. During vitrectomies, an adhesion of the vitreous to the flap or the operculum of the tear was observed, with detachment of the remainder of the posterior vitreous from the retina. Vitrectomy allowed a more complete resolution of posterior tractional forces than scleral buckling, and eliminated the vitreous hemorrhage.
两例眼球挫伤后发生孔源性视网膜脱离的不寻常病例显示，在眼底后部靠近视盘和视网膜大血管处出现视网膜裂孔。在这两例病例中，由于同时存在玻璃体积血，受伤后并未立即发现裂孔。两名患者均通过玻璃体切除术、气液交换和眼内激光光凝术成功治愈。在玻璃体切除术中，观察到玻璃体与裂孔的瓣或盖存在粘连，而后部玻璃体的其余部分与视网膜分离。与巩膜扣带术相比，玻璃体切除术能更彻底地消除后部牵引力，并清除玻璃体积血。
