Product Description
Key Features:
Â
– Center line promotes nasal alignment
– Graduations permit the examiner to understand the correct width and angle of occlusion more accurately
– Handle on top helps reduce intrusion of the examiner into the patient’s ‘personal space’
– Rounded corners make the instrument patient friendly

Bi-Nasal occlusion is used in treatment of patients with acquired brain injury which includes traumatic brain injury (TBI) and stroke, double vision, amblyopia, esotropia, convergence excess, divergence insufficiency, and visual over-stimulation/confusion. Simply stated, it is used to reduce double vision and direct patients to use their peripheral system, helping them to locate objects and judge distances more accurately, which translates to more stable and secure ambulation for most brain injured patients.
The Bi-Nasal Occluder, also called a Bi-Nasal Ruler, can be used to determine the degree of nasal occlusion needed to eliminate or reduce symptoms from the aforementioned conditions. The Bi-Nasal Occluder also allows for repeated measurement and more precise placement of occlusion foils or tape on spectacle lenses.
Bi-Nasal Occlusion works by blocking the nasal field of view, the view which travels the optic pathway and stays on the same side. Bi-Nasal Occlusion encourages crossing the visual information to the opposite side of the brain. It is possible that by blocking the nasal view, which contains primarily high detail sensory retina (midget cells to parvocellular LGN), relief is attained. The binasally-occluded vision may now rely more on the magnocellular pathway for the patient.
The Bi-Nasal Occluder is made of frosted plastic and UV coated for durability.
Occlusion gradients from 85 mm to 30 mm are provided in 5 mm increments. Finger hold at  the top and centering line are provided for easy handling.
Further, the Bi-Nasal Occluder can then be used to properly cut and position the Bangerter Occlusion Foils. Towards this end we offer a Bi-Nasal Occluder Kit which includes the Occluder, quantity two (2) Bangerter Light Perception Foils and tweezers which provides enough material for 4-6 patients. This application is covered in the instructions. Tweezers may vary from photo.
