Clinical Profile of Low Vision Patients Attending in Low Vision Clinic in a Tertiary Care Hospital

The purpose of the study was to determine the disease profile of patients attending the low vision clinic of a tertiary eye care hospital at National Institute of Ophthalmology & Hospital (NIO&H), Dhaka, Bangladesh July 2016 to June 2017. Low vision and blindness are major causes of morbidity and an economic burden on the individual, family and the country. Low vision service has emerged as a major challenge faced by the developing countries .so prompt diagnosis; early treatment and early use of low vision devices can improve the quality of life. It was a prospective observational study conducted in low vision clinic at a tertiary care hospital in Bangladesh for one year. A total 419 patient, aged 6-60 years among them 267(63.7%) were male and 152(36.3%) were female. The leading causes of low vision in patient attending the low vision clinic were Retinitis pigmentosa (31.3%) macular dystrophy/stargards diseases & maculopathy (20.3%) and myopia with macular degeneration (14.8%). The percentage of visual impaired (6/18-6/60) were 38.3%, severely visual impaired (<6/60-3/60) were 24.4% & (<3/60) 37.3%. Almost all the patient was prescribed spectacles and Telescope for distant vision, Hand held magnifier and video magnifier were prescribed for near vision. Vision improved with low vision devices (6/18 or better) in 49.5%, (6/18-6/60) in 47.3%, (<6/60-3/60) in 2.8%, (<3/60) in 0.3% patient. Vision with low vision devices were significantly changes (p=0.001). The present study shows that hereditary ocular anomalies (Retinitis pigmentosa, macular dystrophy, myopic degeneration) and amblyopia were more common causes of low vision in this part of world.
