Michael Wall MD

Dr. Wall is a Professor of Ophthalmology Visual Sciences and Neurology at the University of Iowa. Dr. Wall's research has two arms. The first is to develop strategies of visual field testing that detect visual field defects at an earlier stage and visual field change at an earlier time. To achieve these goals, we have been studying mechanisms of perimetric variability. We have been funded for this with a VA Merit review for the past 22 years. During this time we have shown that a substantial portion of the variability of perimetry is due to the stimulus size chosen.
