Purpose: To analyze utilization of prescribed Low Vision devices in cases of Optic Atrophy.
Methods: Prospective, Cross Sectional Study was performed in tertiary eye care centers within the period of 3 years. Screening was done and subjects were taken to tertiary centers for further evaluation. Visual functions along with slit lamp and fundus evaluation was performed and treatment was provided accordingly. Subjects who were in the criteria of low vision was enrolled in the study and given low vision aids as per the need. Training of usage of devices was given for 15 days and follow up was taken after 3 months to know utilization of prescribed low vision devices. Data was collected and analyzed using SPSS software version 20.
Results: 97% of subjects were enrolled into the study. Out of them, 61% were males. Spectacle Refraction was best achieved by Stenopaeic Slit refraction and given full prescription where required. For distance, Monocular Hand Held Telescopes, Clip on Telescopes or Spectacle Mounted Telescopes were prescribed. For near, Aspherics, Hand Held Magnifiers, Stand Magnifiers And Or Reading Stand were prescribed. Photochromatics or Dark Sunglasses were prescribed for reduction of glare. On 3 month follow up, it showed that Monocular Hand Held Telescopes of variable power (69%) was accepted maximum for distance. Photochromatics (96%) was maximally accepted for reduction of glare. For near, Non Optical Device – Reading Stand (78%) was accepted by most of the subjects. It shows that optical devices help much more for distance while non optical devices should be preferred for near work.
Conclusions: In cases of optic atrophy, Monocular Hand Held Telescope of variable power as per the need, Photochromatics for glare reduction and Reading Stand for near work should be prescribed
