This study was to determine the causes of visual impairment and to identify the low vision prescribing pattern among Low Vision Clinic (LVC) patients in the Sibu Hospital. This study was conducted retrospectively among 41 patients attending the LVC, Sibu Hospital. Patients’ demographic characteristics, causes of low vision and blindness, and types of low vision devices prescribed were recorded and analysed for 21 (52.5%) males and 19 (47.5%) females. The mean age was 39.38 ± 17.98 years. The main causes of visual impairment were retinal dystrophies in 12 cases (30.0%) followed by neurological causes in 9 cases (22.5%), glaucoma in 8 cases (20.0%), and acquired macular disorders in 4 cases (10.0%). A total of 27 low vision devices were dispensed, 85.2% (n = 23) were near devices and 14.8% (n = 4) were distance devices. The most frequently prescribed low vision devices (LVD) were video magnifiers (37.0%), followed by hand magnifiers (22.2%), spectacle magnifiers (14.8%), telescopes (14.8%) and stand magnifiers (11.1%). The main leading causes of visual impairment in LVC Sibu Hospital were retinal dystrophies. Video magnifiers were the most common type of low-vision device prescribed. A prompt comprehensive screening is urged for family members with retinal dystrophies to detect the diseases early and hence timely exposure to low vision care and rehabilitation. Familial counselling on inherited retinal diseases and better screening by primary eye care providers are required. Low vision services should be an integral part of the eye care systems in Malaysia.
