远用光学助视器在视力残疾患者康复中的临床应用

Clinical application of the distant visual aids for visual disability patients

目的:观察远用助视器在视力残疾患者的临床应用效果。方法:对32例视力残疾患者进行屈光矫正后,然后再运用单筒望远镜式助视器或眼镜式助视器提高和改善患者远用视力。结果:配用远用助视器平均视力(logMAR视力)为0.24±0.23;而在屈光矫正的基础上再应用助视器矫正的患者平均视力(logMAR视力)为0.11±0.25,即戴镜后使用远用助视器后视力好于未戴镜患者(t=4.56,P<0.05)。试戴远用助视器后25例远视力≥0.3,脱残率为78%;进行屈光矫正后,该组病例脱残率为94%(P<0.05)。结论:远用光学助视器在视力残疾患者康复有着重要作用,它可提高患者的远用视力,尤其强调在屈光矫正的基础上应用光学助视器临床疗效更为明显。

AIM：To investigate the effect of the distant visual aids for visual disability patients in clinical application·METHODS：Thirty-two visual disability patients were given full refractive correction and then offered binocular or monocular telescopes as low vision aids in order to improve patients＇ distance visions·RESULTS：In cases,the application of the distant visual aids were obtained acceptable vision.Visual acuity of the distant visual aids（logMAR） was 0.24±0.23,but lower than that of patients who were given both full refractive correction and low vision aids,their visual acuity（logMAR） was 0.11±0.25,there was statistically significant improvement.There was a 94% rate of overcoming the handicap when they were given both full refractive correction and low vision aids,higher than that of patients who were only given low vision aids,there was statistically significant improvement·CONCLUSION：The distant visual aids is important and effective for visual disability patients.The importance of ametropic correction for rehabilitation of visual disability patients should be recognized.
