Abstract

PURPOSE

To investigate the effect of a new head-mounted electronic visual aid-Acesight on improving visual function and daily activities in patients with tunnel vision.

METHODS

57 patients with tunnel vision participated in this study. The visual field (VF), visual acuity (VA), search ability, time of finding people from the side (TFPS), walking ability, and the subjective feelings of patients with and without Acesight were measured.

RESULTS

15 (36%) patients thought Acesight was "helpful", 16 (28%) thought it was "a little help", and 26 (46%) believed that it was "not helpful." The proportion of people aged < 60 years found Acesight helpful was higher. When wearing Acesight, the average horizontal VF diameter (°) (35.54[8.72]) and vertical VF diameter (°) (26.63[5.38]) were larger than those without visual aids (20.61[9.22], 18.19[6.67]) (P all < 0.001). The average TFPS before and while wearing the Acesight was 1.77s(0.32) and 1.19s(0.29), respectively (t = 14.28, P < 0.001). The average search times, number of collisions, walking speeds when wearing the Acesight were not statistically different from those without visual aids (P all > 0.05).

CONCLUSION

More than half of patients with tunnel vision found the Acesight helpful, and a higher proportion of those aged < 60 years old found it helpful. Acesight can expand the horizontal and vertical VF of patients with tunnel vision and can enable patients to detect objects coming from the side earlier.

摘要

目的

研究新型头戴式电子视觉辅助器 Acesight 对改善隧道视野患者视觉功能和日常活动的效果。

方法

本研究纳入 57 例隧道视野患者。测量患者的视野（VF）、视力（VA）、搜索能力、从侧面发现人的时间（TFPS）、行走能力以及有无 Acesight 时的主观感受。

结果

15 例（36%）患者认为 Acesight“有帮助”，16 例（28%）认为“有一点帮助”，26 例（46%）认为“没有帮助”。年龄<60 岁的患者认为 Acesight 有帮助的比例更高。佩戴 Acesight 时，平均水平 VF 直径（°）（35.54[8.72]）和垂直 VF 直径（°）（26.63[5.38]）大于不使用视觉辅助器时的水平 VF 直径（°）（20.61[9.22]）和垂直 VF 直径（°）（18.19[6.67]）（P 均<0.001）。佩戴和不佩戴 Acesight 时的平均 TFPS 分别为 1.77s（0.32）和 1.19s（0.29）（t=14.28，P<0.001）。佩戴和不佩戴 Acesight 时的平均搜索次数、碰撞次数和行走速度无统计学差异（P 均>0.05）。
