Testing retinal sensitivity in ocular hypertension using automated colour perimetry

Abstract

The aim of this study was to compare the sensitivity of the white and the blue stimuli using macular full threshold and peripheral 60-4 testing strategies of the Humphrey field analyzer in patients with ocular hypertension. Ninety-eight eyes of 49 patients with ocular hypertension were examined using white and blue stimuli. A decrease in retinal sensitivity in six eyes (6.12%) was more prominent in the macular full threshold and peripheral 60-4 threshold tests when the blue stimulus was used. The results show that these tests are important in detecting the early retinal damage.
