Abstract：
UNASSIGNED: Age-related macular degeneration (AMD) is a common cause of blindness, residual damage to macular area in spite of treatment necessitates visual rehabilitation by means of low-vision aids (LVAs).
UNASSIGNED: Thirty patients suffering from different stages of AMD requiring LVAs were included in this prospective study. Patients with nonprogressive, adequately treated AMD were enrolled over a 12-month period, prescribed requisite LVAs and followed-up for a minimum 1-month period. Before and after provision of LVAs, near work efficiencies were evaluated by calculating reading speed as words per minute (wpm) under both photopic and mesopic light conditions, and impact of poor vision on activities of daily living (ADL) was quantified by modified standard questionnaire based on Nhung X et al. questionnaire.
UNASSIGNED: Of the 30 patients mean studied with mean age of 68 ± 10 years, 20 patients (66.7%) had dry AMD in better eye and 10 (33.3%) had wet AMD. Post-LVA, near visual acuity improved significantly and all cases were able to read some letters on near vision chart with an average improvement of 2.4 ± 0.96 lines. The different LVAs prescribed were high plus reading spectacles (up to 10 D) in 23.3%, hand-held magnifiers in 53.3%, base in prisms in 10%, stand held magnifiers in 6.7%, and bar and dome magnifiers in 3.3%.
UNASSIGNED: LVAs are effective in visual rehabilitation in patients with AMD. Self-reported reduction in visual dependency and improvement in vision-related quality of life post use of aids corroborated perceived benefit.

摘要：
■年龄相关性黄斑变性（AMD）是失明的常见原因，尽管进行了治疗，但黄斑区的残余损伤仍需要通过低视力辅助（LVA）进行视觉康复。
■这项前瞻性研究包括30名患有不同阶段需要LVAs的AMD患者。非进行性患者，经过充分治疗的AMD在12个月期间被纳入，规定必要的LVAs，并随访至少1个月。在提供LVA之前和之后，通过在明视和中视光条件下将阅读速度计算为每分钟单词（wpm）来评估接近工作效率，视力不良对日常生活活动（ADL）的影响通过基于NhungX等人的改良标准问卷进行量化。问卷。
■在研究的30名患者中，平均年龄为68±10岁，20例患者（66.7％）在较好的眼睛中患有干性AMD，10例（33.3％）患有湿性AMD。LVA后，近视力明显提高，所有病例均能在近视力图上阅读一些字母，平均提高2.4±0.96行。规定的不同LVA为23.3％的高加阅读眼镜（最高10D），手持放大镜占53.3%，以棱镜为基准的10%，站立式放大镜占6.7%，酒吧和圆顶放大镜占3.3%。
■LVAs对AMD患者的视觉康复有效。自我报告的使用辅助工具后视觉依赖性的降低和与视觉相关的生活质量的改善证实了感知的益处。
