Abstract

Background: A the most recent (1997) project estimates world blindness to some 45 million blind, and an additional 135 million visually disabled (those with low vision). About 90% of the world’s blinds live in the developing world. It is estimated that there are 9-12 million blind people in India which amounts for one- fourth of all the blind people worldwide.
Objective: To evaluate the low vision patient, to improve the quality of life with low vision aids of visually impaired patient and rehabilitation of low vision aids as per the need of the patient.
Material and Method: Total 110 patients were taken for the evaluation of low vision and its rehabilitation in various disorders. The patient underwent a comprehensive clinical low vision examination, functional evaluation, assessment of patients need and demonstration of low vision devices.
Result and interpretation: Majority of the patient were between the age group of 10-29 years, that is, about 45.46% of the total patients in study and  males were slightly more 60(54.54%) as compared to females 50 (45.46%).The most patients have BCVA for distance before giving low vision is 5/60 – 3/60 in 60(54.54%)  followed by 6/18-6/60 in 25 (22.72%) and 2/60-PL positive in 25 (22.72%) which is improved up to 5/60-3/60 in 50 (45.45%) followed by 6/18-6/60 in 40 (36.36%) and 2/60-PL positive in 20(18.18%) after prescribing low vision aids. The BCVA for near before giving low vision aids is ≤ N/36 in 60 (54.54%) followed by N/12-N/18 in 40 (36.36%) and N/10 in 10 (9.09%) patients, which is improved up to N/10 in 55 (50%) patients followed by N/12-N/18 in 35 (31.81%) and ≤N/36 in 20 (18.18%) after prescribing low vision aids.
Conclusion: The incidence of low vision is mostly underestimated due to lack of knowledge about this condition. By proper diagnosis and evaluation, low vision patients can be rehabilitated to perform their day to day activities thus improving their quality of life.
