Uitkomstmaten
Primaire uitkomstmaten
differences between interocular difference in visual acuity, binocular summation ratio, Interocular balance point in binocular brightness integration as well as the dominance ratio in rivalry and finally direction of motion integration.
Achtergrond van het onderzoek
To determine the influence of glaucoma on binocular binocular visual function we propose to measure (1) contrast sensitivity functions, monocularly and binocularly, (2) brightness integration, (3) motion integration, and (4) resolving conflicting information between eyes (binocular rivalry).
Doel van het onderzoek
We hypothesise that glaucoma patients with non-overlapping visual field defects have poorer binocular visual performance while performing complex visual tasks than would be predicted from their visual field. Knowledge on this topic is highly relevant as it dictates the necessity of (intensifying) glaucoma treatment in those patients without overlapping visual field defects
