目的 探讨前部增殖性玻璃体视网膜病变（ｐｒｏｌｉｆｅｒａｔｉｖｅ ｖｉｔｒｅｏｒｅｔｉｎｏｐａｔｈｙ,ＰＶＲ）视网膜脱离的临床特点及其手术治疗效果,方法 分析Ｃ～Ｄ级ＰＶＲ视网膜脱离患者８３例（８３只眼）;并针对其前部和后部病变,采用不同的手术方法进行治疗。结果 ８３例视网膜脱离患者中,前部ＰＶＲ３４只眼,占４１．０％;后部ＰＶＲ４９只眼,占５９．０％,发病年龄前者较轻,平均２８．５岁;后者３８．

Retinal detachment with anterior proliferative vitreoretinopathy and its surgical treatment

OBJECTIVE: To explore the clinical characteristics and surgical results of retinal detachment in eyes with anterior proliferative vitreoretinopathy (PVR). METHODS: 83 patients (83 eyes) of retinal detachment with grade C-D PVR were studied. Different surgical methods were used in treating anterior PVR and posterior PVR, respectively. RESULTS: Among the 83 patients, anterior PVR was in 34 eyes (41.0%) and posterior PVR 49 eyes (59.0%). The anterior PVR occurred in younger patients, mean age 28.5 years, more in male patients (85.3%) and more in grade D of PVR (55.9%); in the posterior PVR, the mean age was 38.9 years, 63.3% of patients were male and 24.5% of patients were in grade D of PVR. Eighty-three patients had a mean postoperative follow-up of 12.9 months. Complete retinal re-attachment occurred in 24 eyes (70.6%) with anterior PVR and in 38 eyes with posterior PVR (77.6%; chi(2) = 0.51, P > 0.1). The final corrected visual acuity >or= 0.05 was in 11 eyes with anterior PVR (32.4%) and in 22 eyes with posterior PVR (44.9%; chi(2) = 1.32, P > 0.1). CONCLUSIONS: Eyes with anterior PVR have different clinical characteristics and worse surgical conditions when compared with eyes of posterior PVR. However, by the use of modern vitreoretinal surgery, the outcome in eyes with anterior PVR may become similar to that of posterior PVR.
