In this retrospective study of 261 patients (181 female and 80 male) the results obtained in a special low vision clinic are described. The mean age of the patients was 73.5 years (range 16-95 years). Visual acuity of the best eye was less than or equal to 0.08 in 26 patients (10.0%); better than 0.08 but less than or equal to 0.25 in 130 (50%); 0.30 in 62 (23.8%) and better than 0.30 in 42 patients (16.1%). Persons with a visual acuity better than 0.30 either could not read normal print or had restricted visual fields. Main causes of visual impairment were macular degeneration (38.9%), diabetic retinopathy (16.1%), glaucoma (8.4%) and cataract (7.4%). Low vision aids could be prescribed for 208 persons (79.7%). Follow-up of an average of 12 months (range, 3-22 months) was carried out in 250 cases (96%). In this period 24 patients (9%) died. At least 161 persons (62%) used their aids regularly, i.e. 77% of the patients who were given a low vision aid.
在这项对261例患者（181例女性和80例男性）的回顾性研究中，描述了在一家特殊的低视力诊所获得的结果。患者的平均年龄为73.5岁（范围16 - 95岁）。最佳眼的视力在26例患者中小于或等于0.08（10.0%）；在130例中优于0.08但小于或等于0.25（50%）；在62例中为0.30（23.8%），在42例患者中优于0.30（16.1%）。视力优于0.30的人要么无法阅读正常印刷品，要么视野受限。视力损害的主要原因是黄斑变性（38.9%）、糖尿病视网膜病变（16.1%）、青光眼（8.4%）和白内障（7.4%）。可为208人（79.7%）开具低视力辅助器具。250例（96%）进行了平均12个月（范围3 - 22个月）的随访。在此期间，24例患者（9%）死亡。至少161人（62%）定期使用他们的辅助器具，即77%接受低视力辅助器具的患者。
