영문 초록

Purpose: To investigate the color vision defect in diabetic patients using the SNU computerized color test (SCCT). Methods: From May to September 2003, diabetic patients with visual acuity 0.6 or better underwent various examinations including biomicroscopy, fundus photography, Ishihara color test, Hardy?Rand?Rittler (HRR) test, Seohan computerized hue test (SCHT), and SNU computerized color test. The SCCT was developed by using the Matlab 6.0 program. Results: A total of 160 eyes of 82 diabetic patients were included. Thirty?two patients had no diabetic retinopathy, 19 had mild nonproliferative diabetic retinopathy (NPDR), 12 had moderate NPDR, 12 had severe NPDR, and 7 had proliferative diabetic retinopathy (PDR). In the all diabetic patients, the average total error score (TES) of SCHT was 189 and that of SCCT was 8.5; in patients without diabetic retinopathy, the scores were 125 and 3.64; in patients with mild NPDR, 185 and 8.16; in patients with moderate NPDR, 209 and 11.1; in patients with severe NPDR, 288 and 15.6 ; and in patients with PDR, 324 and 17.6 respectively. On the HRR test, patients without diabetic retinopathy had 1 tritan defect; those with mild NPDR 2 tritan, 2 protan, and 2 deutan defects : those with moderate NPDR, no color defects ; and those with severe NPDR, 2 tritan, and 2 protan defects, and 1 deutan defect. Conclusions: In diabetic patients, TES of SCHT and SCCT was higher according to the severity of diabetic retinopathy. SCHT and SCCT were more useful than HRR test.
