作者对57例(59眼)白内障手术中有玻璃体脱出经前部玻璃体切割处理的病人进行了长期随访。平均随访时间为26个月。病人平均年龄60岁。53眼(90%)白内障囊内或囊外摘出术,6眼(10%)白内障乳化取出术。37眼(63%)用自动玻璃体切割器切割,22眼(37%)用纤维素海绵切割。除全面眼部检查外,视力低于20/40者,作了眼底荧光血管造影。术后最好视力和最后视力,两种切割方法间无明显差异(P>0.05)。最后视力低于20/40者主要是因慢性或短暂的黄斑囊性水肿。但两种切割术的黄斑囊性水肿发生率相同。前部玻璃体切割术后,症状性黄斑囊性水肿的发病率为28～42%。
The authors conducted a long-term follow-up of 57 patients (59 eyes) with vitreous prolapsed anterior vitrectomy during cataract surgery. The average follow-up time was 26 months. The average patient age is 60 years old. Fifty-three (90%) cataract extracapsular or extracapsular cataract extraction and six (10%) cataract phacoemulsification were performed. Eighteen eyes (63%) were cut with automatic vitrectomy and 22 eyes (37%) were cut with a cellulose sponge. In addition to a complete eye examination, visual acuity of less than 20/40, made fundus fluorescein angiography. Postoperative best visual acuity and final visual acuity, no significant difference between the two methods of cutting (P> 0.05). The final visual acuity below 20/40 is mainly due to chronic or transient macular cyst edema. However, the incidence of macular cyst edema of the two incisions was the same. After anterior vitrectomy, the incidence of symptomatic macular cyst edema is 28 ~ 42%.
