Using optical visual aids, visual rehabilitation was performed in 14 cases (25 eyes) for low-vision patients with aging macular degeneration (AMD). With distance aids, visual acuity improvements were recorded for 24 eyes (95 percent) out of 25 eyes. Twelve eyes (48 percent) achieved vision equal to or better than 0.4. Utilizing near visual aids, the near visual acuity for all eyes (100 percent) were improved. Thirteen eyes (52 percent) received near vision equal to or better than 0.5. Ten patients were able to read No. 5 equal to or better than 0.5. Ten patients were able to read No. 5 Chinese print (corresponding visual angle is 0.67 at 30 cm of reading distance). The reading success rate was 71.4 percent. The results suggest that the application of visual aids is an effective method to improve the distance and near visual acuity of low vision patients with AMD.
使用光学助视器，对14例（25只眼）患有年龄相关性黄斑变性（AMD）的低视力患者进行了视觉康复治疗。使用远距助视器时，25只眼中有24只眼（95%）的视力得到了提高。12只眼（48%）的视力达到或优于0.4。使用近距助视器时，所有眼睛（100%）的近视力均得到提高。13只眼（52%）的近视力达到或优于0.5。10例患者能够以0.5或更好的视力阅读五号字。10例患者能够阅读五号中文印刷字体（在30厘米阅读距离处对应的视角为0.67）。阅读成功率为71.4%。结果表明，使用助视器是提高AMD低视力患者远距和近距视力的有效方法。
