Clinical trials: Visual Field, open to volunteers
Visual Field Defect, Peripheral
Virtual Reality Visual Field Testing as an Alternative in Childhood Eye Disease
The purpose of this study is to test a new way of measuring the peripheral vision (called a visual field test) using a device which can be worn as goggles rather than being a large instrument the patient must sit at.
