Laser administered proliferative macular edema according Study Early Treatment criteria. we embarked cross-sectional study evaluate prevalence visual impairment At study, 205 insulin-taking age diagnosis less than 30 years, Out those, present 106 (52%), 26 (13%) 19 (9%). Visual acuity 196 (96%) equal or better 6/12 their eye, 6 (3%) had 6/18-6/36 (1%) worse 6/60 legally blind. concluded low compared other countries. out 245 Type diabetes, 100 (41%), 17 (7%) 24 (10%) edema. A total 224 (91%) 4 (1.6%) those population-based studies from 1992 examined ways more efficient by identifying subgroups risk developing required therefore needed frequent screening. studied whether could be trimmed excluding children examining without every year. all under 15 went through files 1980 also followed two found no establishing later. Our results indicated 12 do not need Biannual seemed suffice retinopathy. (ABSTRACT TRUNCATED)
