RESUMO
PURPOSE: To investigate the quality-of-life-related goals of low-vision patients, the causes of visual impairment, and the low-vision rehabilitation services at a Thai national tertiary referral center. SUBJECTS AND METHODS: A review was conducted on the medical records of patients attending the Low Vision Rehabilitation Clinic, Siriraj Hospital, Bangkok, Thailand, between 2012 and 2016. RESULTS: A total of 992 patient records were included, comprising of 760 adults (aged over 15 years) and 232 children (aged ≤15), with a mean age of 52.2 and 5.4 years, respectively. The retina was the most common anatomic site of visual impairment. Among the adults, the most common ocular condition was retinitis pigmentosa (28.3%), followed by age-related macular degeneration (10.3%), glaucoma (10.0%), and diabetic retinopathy (9.6%). As for the children, the most common ocular conditions were cortical visual impairment (17.7%), optic nerve hypoplasia (13.4%), and retinopathy of prematurity (9.5%). More patients had low vision (a visual acuity of <6/18-3/60) than blindness (a visual acuity below 3/60). The most commonly stated goals among the adults were reading, writing, and performing near tasks (34.7%), and independent mobility (21.3%), whereas for children, the most frequently indicated goal was visual and developmental stimulation (38.4%). The services most often provided for the adults were the prescribing of visual aid devices (51.8%) and orientation and mobility training (40.7%), while the children most often received visual and developmental stimulation provided by a multidisciplinary team (33.8%). The Thai Government's Universal Health Care Coverage scheme was the most commonly used medical insurance. CONCLUSION: Data from this study can be used to improve low-vision patient care and rehabilitation services, and as input to the further development of national health care policies for low-vision patients.
