Outcome measures
Primary outcome
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.
Secondary outcome
NA
Background summary
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).
Study objective
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

Inclusion criteria
Glaucoma patients between ages 50 and 80, who visit the ophthalmology clinic at University Medical Center Groningen, that have provided the signed informed consent form and meet the inclusion-exclusion criteria. Healthy subjects between ages 50 and 80, who have provided the signed informed consent form and returned the questionnaire with results which do not indicate ophthalmic nor binocular abnormalities.
Exclusion criteria
Glaucoma Patients Visual acuity less than 0.8 Non-glaucomatous visual field loss. Healthy Subjects Visual acuity less than 0.8 Any binocular dysfunction Any visual field loss Intraocular pressure above 21 mmHg Positive family history of glaucoma.
