Visual Field Test
Visual field testing is done to detect any visual field loss that you may have. Visual field loss may result from disorders or diseases of the eye, optic nerve, or brain. A common method of visual field testing involves having the patient focus at a point while flashes of light are displayed on a screen. The patient pushes a button whenever they see a flash of light and a computer maps a record of their responses. The physician will then review the results with the patient to determine the extent of visual field. Our retinal experts at Saskatoon Retina Services can help with this process.
