  • Patent number: 7275830
    Abstract: Methods and systems for performing an eye test and for detecting eye disease. A test pattern is presented to an individual. The individual fixates an eye on a fixation target. The test pattern is then hidden and a second test pattern is displayed at a different location. The individual then compares the perceived second test pattern with a pre-defined reference pattern. These steps are repeated several times, while varying the location of presentation of the patterns. Alternatively, the individual fixates on a presented fixation target. A test pattern is presented to the patient and then disappears. The individual compares the perceived pattern, with a pre-defined reference pattern. These steps are repeated while changing the location of presentation of the test pattern. It may then be determined whether the individual has an eye disease based on the comparisons.

  • Patent number: 7220000
    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.

  • Patent number: 6656131
    Abstract: A method and system for detecting eye disease. A pattern is displayed on a screen to an individual, who is made to fixate his vision on a point in the pattern. The pattern is then hidden and a second pattern is displayed. The individual then compares the second pattern, as perceived by him, with a pre-defined pattern. These steps are then repeated several times. It is then determined whether the individual has an eye disease based on the comparisons.
