Characteristics of 681 Low Vision Patients in Korea

ABSTRACT

The purpose of our study was to evaluate the characteristics and the changes of low vision patients over ten years in Korea, and to establish useful data for planning low vision services, active care and rehabilitation. We conducted a retrospective study of 681 low vision patients who visited two low vision clinics in Seoul from 1995 to 2008. Age and sex distribution, cause of low vision, type of prescribed low vision aids, and changes of the characteristics were reviewed. In result, male were more than female. The age group between 11 and 20-yr-old (18.1%) was the largest age group. Optic atrophy (28.3%) was main causes of low vision. However, elderly low vision patients is increasing and macular degeneration is becoming a leading cause of low vision (P<0.05). One thousand five low vision aids (LVAs) were prescribed for 681 patients (1.46+/-0.62 aids for each patient). Near LVAs were prescribed more than distance LVAs. In most patients, the use of LVAs improved both near and distance visual function. This study is the first survey of a large number of low vision patients over a ten year period in Korea. On the base of this study, the planning of low vision services and more active rehabilitation for low vision patients, especially elderly patients, need in Korea.
