Abstract:
This article is a general view of evaluated acquired color vision defects in the early stages of primary glaucoma and in patients at risk for glaucoma. The articles published until now indicates a decrease in color discriminating sensitivity in the short wavelength part of the visible spectrum in patients with glaucoma as well as in patients with ocular hypertension. It has been found a positive correlation between the blue-yellow color vision defects and the perimetric changes in the glaucomatous eyes. Blue-yellow color vision testing with the anomaloscope may serve as an additional test in the early diagnosis of glaucoma but the absence of dyschromatopsia does not exclude the disease.
