Assessing the Efficacy of the Dynamic Eye Misalignment Retroversion System (DEMRS) Prototype with Normal and Strabismus Subjects

Strabismus is a medical term used to define eye misalignment conditions that prevent both eyes from focusing on the same target simultaneously. Apart from having an aesthetic impact on the subject, strabismus is a disability that prohibits the correct perception of depth. The purpose of going through treatment is to realign the "bad" (strabismic) eye, so that it fixates on the same target as the "good" (dominant) eye. This paper presents the clinical evaluation of the prototype of a novel system, called Dynamic Eye Misalignment Retroversion System (DEMRS), which adjusts the light rays such that both eyes are stimulated by the correct target, simultaneously at various distances and directions. Clinical evaluation experiments were conducted under lab conditions, using subjects with normal vision and strabismus, between the age of 8 and 98 years. Without using the DEMRS, 50:4% of the test cases, showed successful binocular fusion. When the DEMRS was used, 88:8% of the test cases showed successful binocular fusion. The results indicate that the DEMRS is able to restore successfully the correct perception of depth, through binocular vision, for young children, adults and elders.
