Our state-of-the-art computerized visual field analysis can detect changes in the sensitivity of your side vision. It is used to measure your entire field of vision including both your central and peripheral vision. The visual field test can help us detect, diagnose, and treat many eye and neurological issues including those caused by glaucoma, retinal detachments, tumors, and other conditions. All of our patients at Ramona Eye Care undergo the peripheral vision testing using the Humphrey Matrix FDT (Frequency Doubling Technology) Perimeter.
