Glaucoma, Colour Vision and Visual Field

Overview

The authors investigated changes of the visual field and colour vision in patientswith open-angle glaucoma. These visual functions were examined also in a controlgroup of healthy subjects of similar age. For examination of the visual field theauthors use the statistical programme of the Tübingen perimeter, and colourvision was assessed using Lanthony s Panel D-15. The statistical parameters ofthe visual field (MS, MD, LV) in the group of eyes with open-angle glaucoma andin the control group did not differ significantly. A significant difference betweengroups was found only in the oldest age group. The acquired defects of colourvision were in the group with open-angle glaucoma significantly higher than inthe control group and the highest number of acquired defects was found again inthe oldest age group. In particular defects in the blue-yellow area were obser-ved.Statistical analysis of the relation between changes of the visual field anddefects of the colour vision did not reveal a significant correlation of these visualfunctions in the group of eyes with open-angle glaucoma. Important factors in theevaluation of the visual field and colour vision of patients with open-angleglaucoma are the age of the investigated subjects, repeated tests of visual functionsand long-term follow up.
