Vitreous hemorrhage and fibrovascular proliferation after laser-induced chorioretinal venous anastomosis

·AIM:To describe a case in which vitrectomy was required for vitreous hemorrhage and fibrovascular proliferation after laser-induced chorioretinal venous anastomosis (LCVA) for non-ischemic central retinal vein occlusion (CRVO).·METHODS:Observational case report.·RESULTS:A 72-year-old man complained of central scotoma in the left eye,and was diagnosed as suffering from non-ischemic CRVO.LCVA was performed in another hospital.Although favorable visual function was briefly maintained postoperatively,severe vitreous hemorrhage developed in his left eye,necessitating vitrectomy.·CONCLUSION:Considering that LCVA carries a risk of serious complications,we must apply this treatment with caution,especially in ethnic groups,such as the Japanese,in whom pigmentation reacts to photocoagulation excessively.·

激光诱导脉络膜视网膜静脉吻合术后玻璃体出血及纤维血管增生1例(英文)

目的:报告1例非缺血性中央视网膜静脉阻塞的患者实施激光诱导脉络膜视网膜静脉吻合术后出现玻璃体出血及纤维血管增生而进行玻璃体切割术。方法:病例报告。结果:患者,男,72岁,主诉左眼中央有一暗点,诊断为非缺血性中央视网膜静脉阻塞。在其他医院实施激光诱导脉络膜视网膜静脉吻合术。术后患者左眼视力短暂恢复,但并发严重的玻璃体出血,遂来我院实施玻璃体切割术。结论:激光诱导脉络膜视网膜静脉吻合术有发生严重并发症的危险,要求临床医师慎重选择,特别是对于某些种族(比如日本),因为色素沉着可引起光凝过度反应。
