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.
