Abstract: Methods and apparatus for the treatment of the eye to reduce pain can treat at least an outer region of the tissue so as to denervate nerves extending into the inner region and reduce the pain. For example, the cornea of the eye may comprise an inner region having an epithelial defect, and an outer portion of the cornea can be treated to reduce pain of the epithelial defect. The outer portion of the cornea can be treated to denervate nerves extending from the outer portion to the inner portion. The outer portion can be treated in many ways to denervate the nerve, for example with one or more of heat, cold or a denervating noxious substance such as capsaicin. The denervation of the nerve can be reversible, such that corneal innervation can return following treatment.

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.

Abstract: 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.

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.
