Eligibility
Inclusion criteria
Inclusion criteria: 1. Glaucoma patients that are 40 years and older and diagnosed more than a year ago. 2. Has primary open-angle glaucoma. 3. Has visual acuity better or equal to logMAR of 1.00 (6/60) in the worse eye. 4. Has a recent (not more than 6 months) central visual field report with reliable indices
Exclusion criteria
Exclusion criteria: 1. The presence of media opacities precluding visualization of the fundus such as corneal pathology, visually significant cataracts (grade 2 or higher lens morphology according to the Lens Opacities Classification System II (LOCS II), the presence of significant posterior capsular opacity, vitreous opacities, and hemorrhages. 2. A history of ophthalmic surgeries (corneal refractive, cataract and vitreoretinal surgeries) that can decrease contrast sensitivity. 3. The presence of macular or retinal disease (age-related macular degeneration and retinal dystrophies) that can decrease contrast sensitivity. 4. Patients on drugs affecting pupillary size (miotic or mydriatic drugs) that can decrease contrast sensitivity. 5. Poor vision precluding the ability to fixate on the desired target. 6. The presence of neurological diseases like Parkinson's disease, and Alzheimer’s disease.
