Methods devices and systems for detecting eye disease

摘要

A method and system for detecting eye disease. A test pattern (322) is presented to an individual. The individual fixates an eye on a fixation target (228). The test pattern (322) is then hidden and a second test pattern is displayed at a different location than the location at which the first test pattern (322) was presented. The individual then compares the second test pattern, as perceived by him, with a predefined reference pattern. These steps are then repeated several times, while varying the presentation of the patterns. It is then determined whether the individual has an eye disease based on the comparisons. Alternatively, the individual then compares the briefly presented pattern. These steps are then repeated several times while changing the location of presentation of the test pattern. It is then determined whether the individual has an eye disease based on the comparisons.
