Binasal occlusion
Binasal Occlusion is a non-surgical, non-pharmaceutical treatment method used to manage and improve certain visual and perceptual conditions. This method involves the partial occlusion of both nasal visual fields using semi-opaque or opaque materials.
Overview[edit | edit source]
Binasal Occlusion is a technique used in Optometry and Neurology to treat a variety of conditions such as Convergence Insufficiency, Visual Midline Shift Syndrome, and Hemianopsia. The treatment involves the application of semi-opaque or opaque materials to the nasal (inner) sides of both lenses in a pair of glasses. This occlusion reduces the visual input from the nasal fields, which can help to improve visual processing and perception.
Applications[edit | edit source]
Binasal occlusion is used in the treatment of several conditions, including:
- Convergence Insufficiency: This is a condition where the eyes do not work together properly when focusing on a near object. Binasal occlusion can help to reduce the symptoms of this condition by limiting the visual input from the nasal fields.
- Visual Midline Shift Syndrome: This condition can occur after a neurological event such as a stroke. It causes the perceived visual midline to shift, which can affect balance and spatial orientation. Binasal occlusion can help to realign the perceived visual midline.
- Hemianopsia: This is a condition where there is loss of vision in half of the visual field. Binasal occlusion can help to improve visual processing in individuals with this condition.
Procedure[edit | edit source]
The procedure for applying binasal occlusion involves the following steps:
- An optometrist or neurologist will first conduct a thorough eye examination to determine if binasal occlusion is suitable for the patient.
- If suitable, semi-opaque or opaque materials will be applied to the nasal sides of both lenses in a pair of glasses.
- The patient will then be asked to wear these glasses for a specified period of time.
- Follow-up appointments will be scheduled to monitor the patient's progress and make any necessary adjustments to the occlusion.
