OPTICAL CORRECTION AND UTILIZATION OF LOW VISION DEVICES IN MACULAR HOLE

Abstract

PURPOSE: To analyze optical correction and utilization of low vision devices in cases of macular hole.

METHODOLOGY: Prospective cross sectional study was performed at tertiary eye care centers within the period of 2.5 years. Screening was done and subjects were taken to tertiary eye care centers for further evaluation. Subjects with macular hole were included and visual functions along with slit lamp evaluation and fundus evaluation were performed. In refraction, best visual acuity is achieved with stenopaeic slit refraction. Low vision aids were given and subjects were trained to use it. Follow up was taken after 3 months and analyzed which device is used maximum by the subjects having low vision. Data was analyzed using SPSS software version 20.

RESULTS: 46 subjects were enrolled with the mean age group of 64.8 years. 63% subjects were male and 37% were females. Among prescribed devices, 88% of subjects were using spectacles given by stenopaeic slit refraction and 79% were using See TV for distance. For near, 91% of subjects reported using dome magnifier of variable power with extra illumination prescribed as per the need. This should be taken into consideration when refracting and prescribing low vision devices in cases of macular hole.

CONCLUSION: In cases of macular hole, refractive correction should be done with stenopaeic slit. Spectacles and See TV (2x) should be prescribed for distance and dome magnifier of variable power as per need should be prescribed for near.
