Systems and methods are provided for monitoring eye movements of a user, and diagnosing and treating eye conditions substantially in real-time. A visual display device is provided with optical display fields corresponding to eyes of the user, and a controller linked to the device is programmed to measure eye positions with respect to the display device and determine optical deviations in any eye with respect to a central visual axis of the other (dominant) eye. In response to deviations exceeding a first value, an occlusion spot is generated in the display field for the dominant eye of a size corresponding to the degree of optical deviation. The location of the occlusion is continuously adjusted in accordance with real-time movements of the dominant eye based on the received signals from the device. When the optical deviation falls below a second value, occlusion of the dominant eye is disabled.
