Abstract
-
Contrast sensitivity was measured by MCT 8000(R)(Vistech Consultant INC, U.S.A.) in two groups: 23 strabismic amblyopes and 10 anisometropic amblyopes. In general, the amblyopic eyes exhibited a statistically significant loss of contrast sensitivty in both day and night vision. When visual acuity was equated between groups, the anisometropic group had a greater loss of contrast sensitivity at the high spatiaI frequencies and the strabismic group exchibited a similar loss of contrast at all spatial frequencies. Test-retest correlations(average 0.76) were statistically significant, which demonstrated that the test using MCT 8000(R) was reliable.
