Binasal occlusion
Binasal occlusion is a method of partial covering (occlusion) of the visual field of the two eyes in which the sector of the visual field that is adjacent to the nose (the nasal visual field) is occluded for each eye. It is a well-known procedure in vision therapy.
By blocking parts of the image that would be seen by both eyes, binocular occlusion reduces the visual stress that would be related
Cross-fixation which occurs in some strabismus patients with esotropia, and is, in particular, characteristic for a form of infantile esotropia also known as Cianci's syndrome.[citation needed]
Binasal occlusion is used in treatment of patients with sensory deficits due to
According to a 2017 paper,[3] another hypothesis of the effectiveness of binasal occlusion in the treatment of Post Trauma Vision Syndrome, is the tape provides a stationary reference point that the brain can use to help decode the incoming visual information. The term Visual Motion Sensitivity is coined in this paper.
