Correcting Metamorphopsia



A method and apparatus for the evaluation and measurement of metamorphopsia, a visual disorder in which images appear distorted.


This invention provides a very sensitive test for metamorphopsia that detects early retinal changes at a time when therapeutic intervention may be more helpful. The test can be used on a home PC, for greater frequency and ease of use.  The apparatus includes a pattern generation tool that can be used to identify areas of scotoma and to record the level of vision distortion in the patient.  Subsequent measurements track the changes in visual field defects and aid in the development of lenses to correct vision. 


"Correcting Metamorphopsia" was developed by Prof. Kent Stevens of the Department of Computer and Information Science (CIS).
