	abstract = {Effective management and treatment of glaucoma and other visual diseases depend on early diganosis. However, early symptoms of glaucoma often go unnoticed until if significant portion of the visual field is lost, The ability to simulate the visual Consequences of the disease offers potential benefits for patients and clinical education as well as for Public awareness of its signs and symptoms. Experiments using simulated visual field could identify changes in behaviour, for example during driving, that one uses 10 compensate at the early stages of the disease's development. Furthermore, by understanding how visual field defects affect performance of visual tasks, we can help develop new strategies to cope with other devastating diseases macular degeneration. A Gaze-Contingent Display (GCD) system Was developed to simulate an arbitrary visual held in a virtual environment. The system can estimate real-time gaze direction and eye position in earth-fixed coordinates during relatively large head movement. and thus it call be used in immersive projection based VE systems like the CAVE (TM). Arbitrary visual fields are simulated via OpenGL and Shading Language capabilities and techniques that are supported by the GPU, thus enabling fast performance in real time. In order to simulate realistic visual defects, the system performs multiple image processing operations including change in acuity, brightness, color, glare and image distortion. The final component of the system simulated different virtual scenes that the participant call navigate through and explore. As a result, this system creates an experimental environment to study the effects of low vision on everyday tasks such its driving and navigation.},
