[Early disorders of retinal function in diabetes mellitus].
Thirteen insulin-dependent diabetics, aged 13-30 (mean 19.15) years, entered the study. Patients with retinal ischemia, vascular proliferation, or a Snellen acuity below 0.8 were excluded. Ten normal untrained subjects, aged 20-30 (mean 24) years, provided the normal sample. The battery of special visual function tests consisted of: (1) high luminance Pflüger acuity (acuity/luminance/function, rotatable illiterate "E optotypes, screen luminance 10,000 cd/m2); (2) tests combining color vision with demands on spatial resolution: (a) blue-green chromatic acuity (a Velhagen pseudoisochromatic plate served as optotype, the maximum recognition distance being recorded); (b) standard vs mini-panel D-15 color-arrangement tests; (c) blue preferential computerized perimetry (modified Tübingen automatic perimeter, orange adaptive illumination, Schott cut-off filter OG 550, cupola luminance 5 cd/m2).(ABSTRACT TRUNCATED AT 250 WORDS)
