The Visual Field Reading Center (VFRC) under the direction of Dr. Chris Johnson seeks to find better ways of measuring visual function in patients with glaucoma and other eye diseases. Dr. Johnson is one of the world’s authorities on visual field measurement. The Visual Field Reading Center interprets visual function for many multi-center clinical trials as well as many pharmaceutical investigations.
To date, the VFRC has (1) served as the visual field reading center for a multicenter trial involving medication used for Parkinson’s disease, (2) is currently participating in a glaucoma multicenter trial sponsored by a pharmaceutical company, (3) has archived all of the visual field information from the Ocular Hypertension Treatment Study (OHTS), the Optic Neuritis Treatment Trial (ONTT) and the Longitudinal Optic Neuritis Study (LONS), (4) is currently serving as a reading center for a multicenter trial for a medication used for seizure disorders, and (5) has several potential clinical trials pending. Additionally, the VFRC has been working with the perimetry service for the Ophthalmology Department and clinical investigators to provide assistance in the storage,retrieval and interpretation of visual field information.
