Abstract:
:Effects of optical correction on best-corrected grating acuity (vertical (V), horizontal (H), oblique (O)), vernier acuity (V, H, O), contrast sensitivity (1.5, 6.0, and 18.0 cy/deg spatial frequency, V and H), and stereoacuity were evaluated prospectively in 4- to 13-year-old astigmats and a non-astigmatic age-matched control group. Measurements made at baseline (eyeglasses dispensed for astigmats), 6 weeks, and 1 year showed greater improvement in astigmatic than non-astigmatic children for all measures. Treatment effects occurred by 6 weeks, and did not differ by cohort (<8 vs. >or= 8 years), but astigmatic children did not attain normal levels of visual function.

VISION RESEARCH文献大全abstract::The effects of monocular deprivation (MD) on the crossed and uncrossed visual projections were studied using both electrophysiological and behavioural criteria.
