ABSTRACT
PURPOSE:
To determine the reproducibility of morphoscopic contrast sensitivity test values in the patients with primary open angle glaucoma using the Visual Capacity Analyzer (ACV) designed for assessing full visual performance including contrast sensitivity.METHODS:
Morphoscopic contrast sensitivity was measured in each five glaucomatous eyes. The measurement was repeated 5 times under two different luminance level of screen (maximum and 3 cd/m2).RESULTS:
Under maximum luminance background, the coefficients of variation (CV) and the reliability coefficients (RC) for the spatial frequencies examined in this study ranged from 2.1% to 29.3%, from 92.1% to 100.0%, respectively. Under 3cd/m2 luminance level of screen, the CV ranged from 2.7% to 32.0%, and the RC ranged from 90.7% to 99.9%.CONCLUSIONS:
The results indicates that for the spatial frequencies examined, the morphoscopic contrast sensitivity test using ACV shows good reproducibility in glaucomatous patients.
