Study of Profile of Low Vision Patients, Their Clinical Evaluation, Trial of Low Vision Devices and Assessment of Visual Performance of Patients Examined in Low Vision Clinic in a Tertiary Eye Institute

Background: The purpose of study is to study the profile, methods of assessment and trial of various low vision devices of low vision patients in our tertiary eye institute. Methods: A prospective, non- interventional observational study of 150 patients with low vision satisfying the WHO criteria for low vision was conducted over a period of 5 months in our tertiary eye institute after obtaining informed consent and considering the relevant inclusion and exclusion criteria. Patients were subjected to detailed history taking, a thorough ophthalmic examination and low vision assessment at low vision clinic. The suitable type, power and magnification of low vision devices was identified for each patient and trial given. The improvement in the optical performance with the low vision device was noted. The data thus obtained was recorded in excel sheet and analyzed using descriptive statistics. Results: Out of 150 patients, males were 56.7% and 43.3% were females with mean age of 29.4 years. Most common cause of low vision was pathological myopia. 49.3% patients had difficulties in near tasks followed by combined near and distance tasks, difficulties in distance activities, issues with mobility and night vision. Dome magnifier was most common and accepted device prescribed [37.3%] for near tasks and binocular telescope for distance tasks [76.3%]. Conclusion: A thorough clinical evaluation of low vision patients is very important to identify their functional vision and needs. Tailored prescriptions based on individual clinical profiles and preferences are crucial for optimal outcomes.
