ABSTRACT
Objective To evaluate the effectiveness of personalized fitting for visual aids in patients low vision.Methods A total of 173 low vision patients were given visual function evaluation and visual aids fitting,and followed up for the usage of devices after 1 year.Then several variables were analyzed,including vision,the duration of wearing visual aids per day,reasons for discontinuance and existing problems.Results The top 3 underlying etiologies of low vision were high myopia,congenital eye diseases and diabetic retinopathy.As for the usage of visual aids,patients wearing device occasionally accounted for 66.47%,< 1 hour for 4.62%,> 1-2 hours for 19.08%,> 2-3 hours for 4.62%,> 3 hours for 5.20%.The overall efficiency rate of visual aids fitting was 79.77%.and the difference in effectiveness of distance-optical visual aids had no statistical significance (X2 =0.794,P =0.939),but there was significant difference among near-optical visual aids (X2 =12.535,P < 0.05).Among abandoned 23 aids,17 (73.91%) was discarded due to decreased visual acnity,4 (17.39%) due to inconvenience to use,and 2 (8.70%) was unknown to use.Conclusion Personalized fitting can make visual aids more efficient,and the appropriate use of optical visual and electronic visual aids can significantly improve the residual vision by follow-up and enhanced service.
