玻璃体切除术治疗老年黄斑变性所致玻璃体出血的临床观察

Vitrectomy for treatment of vitreous hemorrbage associated with age-related macular degeneration

为了探讨老年黄斑变性引起的玻璃体出血的治疗方法，对该病患者１０例（１０只眼），经平坦部行玻璃体切除术，经随访１／２～２８个月，视力提高者９例，下降者１例。术后视力与黄斑变性的程度，与是否有黄斑下出血有关。手术有利于尽快恢复视力、以便进一步检查眼底，为视网膜下的手术提供基础。

Age-related macular degeneration (AMD)is an aging disorder which has been a leading cause for blindness among old people . The wet type AMD is the main cause which deteriorates visual function rapidly because of the complications including detachment of retinal pigment epithelium,forma- tion of subretinal neovascular membrane and scar, subretinal and vitreous hemorrhage. This assay re-ports the results of vitrectomy for treatment of 10 cases with vitreous hemorrhage associated with AMD.The follow-up periods ranged from 1/2 to 28 months. The visual acuities in 9 cases were increased and in 1 case decreased.The factors a ffecting the postoperative visual acuity,operative complications and therapeutic prospects of the surgery were discussed.
