年龄相关性黄斑变性合并脉络膜新生血管患者的自然病程和视力预后

目的 了解年龄相关性黄斑变性(AMD)合并脉络膜新生血管患者的自然病程和视力预后。方法 对29例(35只眼)未接受激光、放射或手术等治疗的湿性AMD患者,进行全面眼部检查和有计划的定期随诊,包括视力、眼前节检查,直接和间接检眼镜检测,在裂隙灯下用 90D前置镜检查眼底,眼底照相和荧光素眼底血管造影等。结果 随诊5～16年(平均8年),最佳矫正视力在0．1以下者,初诊时为10只眼(眼前手动4只眼),占28．5％;末诊时为23只眼(眼前手动14只眼),占65．7％。初诊时黄斑出血25只眼,玻璃体积血4只眼,随诊中有23只眼反复出血,最多达4次。末诊时仍有7只眼黄斑出血。初诊时7只眼存在黄斑区机化膜,末诊时35只眼均有面积大小不等的机化膜形成。结论 经过长期观察,AMD合并脉络膜新生血管患者的自然病程漫长,黄斑区反复出血,视力预后恶劣。

Natural course and prognosis of visual acuity in patients of age-related macular degeneration with occult choroidal neovascularization

Objective To investigate the natural course and the final visual acuity in patients of age-related macular degeneration with choroidal neovascularization. Methods Thirty five eyes of 29 patients diagnosed as AMD with occult choroidal neovascularization were studied. The eyes which had laser, radiation therapy or surgical treatment were excluded. Visual acuity, fundus examination, fluorescent angiography (FFA) and perimetry test were performed at the first time visit and 5 years following-up at an interval of 1 to 3 months. The average following-up period of time was 8 years (range from 5 to 16 years) which started in 1985 and ended in 2001. Results Initial visual acuity 0.1 or less was shown in 10 eyes(28.5%, only hands movement can be seen in 4 of 10 eyes ),23 eyes(65.7%) with visual acuity of 0.1 or less (14 eyes with vision acuity of hands movement ) on the last visit. 7 of 35 eyes, the final visual acuity improved more than 2 lines, 12 eyes remained the same and 16 eyes had been lost vision more than two lines. At the baseline examination, 25 eyes had macular hemorrhages and 4 eyes had vitreous hemorrhages. The fundus hemorrhages occurred repeatedly 1 to 4 times in 23 eyes during following-up, the macular hemorrhages was detected in 7 eyes at the last visit. At the initial fundus examination, fibrotic membranes were found in 7 eyes; all 35 eyes had disc form scarring with various size in most recent following-up. Conclusion The natural course of Age-related macular degeneration with choroidal neovascularization is prolonged and the final visual prognosis was poor especially in the cases with recurrent macular hemorrhages.
