助视器配戴对低视力儿童康复作用

Rehabilitative functions of visual aids to low vision children

【目的】研究6～14岁低视力儿童行屈光矫正和助视器配戴的视力康复情况。【方法】对6～14岁低视力儿童86例(172眼)检影验光后行屈光矫正和助视器验配。【结果】6～14岁低视力学龄儿童屈光不正以高度近视为主。经单纯屈光矫正后27.4%视力得到提高;在助视器配戴下81.4%视力有提高,其中脱残率58.3%。在助视器配戴下Ⅱ级低视力儿童比Ⅰ级低视力儿童脱残率高(P<0.01)。【结论】屈光矫正和助视器配戴对低视力儿童均有积极的康复作用,助视器的视力康复效果更好。残余视力越好,视力康复越理想。

[Objective] To investigate the visual rehabilitation of 6-14-years old low vision children after refraction correction and using visual aids. [Methods] 86 cases （172 eyes） of low vision patients aged 6-14 years old were recrui- ted. All of them received refraction correction and visual aids after optometry combining retinoscopy. [Results] The re- fractive error o{ 6-14 years old low vision children was mainly high-degree myopia. After refraction correction,27.4% had enhanced visual acuity. After using visual aids, 81. 4% had visual acuity improvement, and 58. 3% became non-disabled. Comparing grade I and grade II low vision children,the latter had higher ratio of becoming non-disabled（P〈0. 01）. [Conclusions] Refraction correction and using visual aids are both positively helpful in rehabilitation and using visual aids has a better rehabilitative effect. Low vision children with better the residual visual acuity have more ideal visual rehabilitation.
