Description:
저시력환자에서 적절하 조명이 시력개선에 미치는 효율성과 일정한 조명에서 볼록렌즈의 형태가 최대교정시력에 미치는 효과를 비교하기 위해 연구를 실시하였다. 28명(36안)의 저시력 환자를 대상으로 조명을 각각 200, 500, 1000, 2000lux로 바꾸어 가면서 근거리 시력을 측정하였고, 500lux하에서 양면볼록렌즈(biconvex lens), 비구면렌즈(aspheric lens), 구면수차제거렌즈(aplanatic lens)를 사용했을 때의 최대교정시력을 측정하였다. 그 결과 200lux의 낮은 조명에 비해 500-1000lux의 조명(P<0.05)이, 그리고 양면볼록렌즈보다 비구면렌즈와 구면수차제거렌즈를 사용했을 때(P<0.01)더 나은 시력을 얻을 수 있었다. 이러한 결과를 참고로 저시력환자의 시력향상에 도움이 될 것으로 안다(한안지 38:1677~1681,1997). To obtain adequate information of illumination and lens types for visual acuity test of low vision patient, the relation between various illumination and vision was evaluated. Visual acuity for near and effective lens types were examined. Among the 28 patients (of 36 eyes), intensities of illumination were set at 200, 500, 1000 and 2000lux and the lenses of biconvex, aspheric and aplanatic were tested. The best visible range of illumination for the low vision patients was 500-1000lux, with lower power diopter for the same visual acuity and with aspherin and aplantic lenses. Results attained by our study may be applied for appropriate condition of illumiation and type of lens in the low vision care(J Korean Ophthalmol Soc 38:1677~1681, 1997).
