| Abstract: | Twenty-five eyes of 25 high-tension glaucoma patients and 25 eyes of 25 low-tension glaucoma patients matched for similar visual field defects had their spectral increment threshold measured. Patients with high-tension glaucoma showed significant losses in both chromatic and achromatic sensitivities when compared with low-tension glaucoma patients. The results support the hypothesis that there may be different mechanisms of damage in glaucoma. |
