业已表明,无晶体为增殖性玻璃体视网膜病变(PVR)的一个危险因素,为明确无晶体眼发生PVR的发病机理,本文对具有PVR与无PVR的无晶体眼进行了对比研究。材料与方法:无晶体裂孔源性视网膜脱离患者174例(182眼)。将既往具有视网膜脱离手术史的患者和白内障术前已发生视网膜脱离的患者排除。182眼中,25眼归为重度PVR(即PVR-D或PVR-C),需行玻璃体切割术。其余157眼为无PVR、轻度PVR(PVR-A或PVR-B)及部分PVR-C。
It has been shown that aphakia is a risk factor for proliferative vitreoretinopathy (PVR). In order to elucidate the pathogenesis of PVR in aphakia, a contrastive study of aphakia with or without PVR was performed. Materials and Methods: A total of 174 patients (182 eyes) with aphakic retinal detachment were included. Patients who previously had a history of retinal detachment and patients who had retinal detachment before surgery were excluded. Of the 182 eyes, 25 eyes were classified as having severe PVR (ie, PVR-D or PVR-C) requiring vitrectomy. The remaining 157 eyes were PVR-free, mild PVR (PVR-A or PVR-B) and partially PVR-C.
