Visual Field
Loss of side vision can be a sign of glaucoma. Visual Field testing measures your side (peripheral) vision. All eye examination patients are first tested on our Humphrey Matrix Visual Field Instrument, a pre-screening instrument which quickly tests your peripheral vision in response to movement.
If further testing is indicated from the doctor's 
examination or the pre-screening test, we will perform a more comprehensive vision field test.
Visual Fields can also detect peripheral visual loss from Macular Degeneration, stroke and other problems causing visual loss.
