Study of Vision Tests Invites People With Glaucoma To Participate

People ages 18 and older with glaucoma are invited to participate in a joint University of Iowa and Iowa City Veterans Affairs Medical Center (VAMC) study to identify the most effective methods for determining whether a patient's vision has changed.

Determining which tests are best at efficiently and accurately detecting changes in a person's visual field should improve a physician's ability to detect change early and thus avoid delays in initiating or changing treatment.

Individuals with glaucoma who have mild to moderate vision loss and no other disease causing vision loss may be eligible to participate in the study. Participants will visit UI Hospitals and Clinics every six months for four years. At each visit, the participant will undergo four vision tests on one eye only. Pictures also will be taken of their optic nerve to look for changes. Visits will last approximately three hours. Compensation is available.

"We are hoping to see differences among the four tests in terms of how efficiently and how early they can accurately detect change," said Michael Wall, M.D., UI professor of neurology and ophthalmology and visual sciences, neuro-ophthalmologist at the UI and VAMC, and principal investigator of the study. "We are primarily looking at glaucoma, but the results of this study should help improve early detection of any disease that causes changes in vision."
