Abstract
Methods and devices for detecting eye disease and for assessing the clinical stage of an eye disease in an individual. The methods include projecting test patterns onto the retina of a tested eye and subjecting the individual to a competing sensory stimuli. The competing stimuli may be of various different sensory modalities including visual, auditory, or other sensory modalities. If the individual perceives a difference in at least one localized part of the perceived image of a test pattern as compared to a predefined reference pattern, the individual provides a response indicative of the difference or differences. The responses are processed to assess the severity of eye disease if a disease is detected, or to determine the clinical stage of a detected eye disease.
