Visual Field Assessment

The visual field refers to the total area in which objects can be seen in the side (peripheral) vision while you focus your eyes on a central point. A visual field test will show whether you have a loss of vision anywhere in your visual field. The pattern of vision loss will help your ophthalmologist diagnose the cause. Diseases that may affect the visual field of the eyes include diabetes, glaucoma, high blood pressure, macular degeneration, multiple sclerosis, optic glioma, overactive thyroid (hyperthyroidism), pituitary gland disorders, retinal detachment, stroke and temporal arteritis.
