Iowa Visual Field Reading Center

Serving Academia and Industry Research Advancements

A division of the Department of Ophthalmology & Visual Sciences
within the university of iowa hospitals & clinics


The UIHC Visual Field Reading Center was established in 2008 to provide clinicians and researchers a means to quickly access and evaluate both raw and processed visual field data and to provide timely feedback to researchers, clinicians, and patients. The Center's main operations are centered around a team of visual field experts led by VFRC Director Michael Wall, M.D. and Co-Director Chris A. Johnson, Ph.D.

The VFRC has retained Bio::Neos, an informatics and software development group, for the past six years, to design, implement and maintain a secure web site and database management system. In this manner, the VFRC is able to provide a paperless means of allowing Clinical Centers to transmit data securely over the internet and to communicate and transmit information to Data Coordinating Centers. In addition, in our fully automated electronic reading center, readers enter their analysis of reliability, visual field change over time and visual field grading according to protocol.
