61 results about "Strabismus" patented technology

Strabismus was originally identified as a Drosophila protein involved in planar cell polarity. Flies with mutated strabismus genes have altered development of ommatidia in their eyes. Vertebrates have two Strabismus-related proteins, VANGL1 and VANGL2 (an alternate name for the Drosophila "Strabismus" protein is "Van Gogh").

Vision-Based Diagnosis and Treatment

Devices for recognizing and responding to Strabismus and Autism are provided herein. Eye-tracking and software analysis are used to identify adverse visual characteristics of both in real time and compelling visual feedback is used to stimulate correction as those events occur.
