Abstract:
The standard vision test using visual acuity is not always an accurate indicator of functional visual loss. The contrast sensitivity was measured in low vision patients. the contrast sensitivity of low vision patients showed a substantila decrease in all spatial frequencies(P<0.001). Of the 34 patients, the preferred eye was the eye with better peak sensitivity in 31 patients(91%) while the perferred eye was the eye with better visual acuity in 24 patients(71%). There were no characteristics of contrast sensitivity according to the diagnosis. The contributions of the contrast sensitivity function to the low vision care are evaluated.
