Which occlusion type is more likely used in the treatment of Post Trauma Vision Syndrome?

• A. Binasal occlusion
• B. Bitemporal occlusion
• C. Full occlusion
• D. No occlusion

Answer: (A)

In Post Trauma Vision Syndrome, visual symptoms often come from the brain having trouble filtering excessive visual input. Reducing peripheral visual stimulation can lessen strain and help with symptoms like photophobia, eye strain, and diplopia. Binasal occlusion does exactly that: it places occluders on the nasal portions of both lenses, blocking the nasal half of each eye's field while leaving the temporal and central portions usable. This lowers overall visual input without eliminating vision entirely, which helps the brain tolerate daily visual tasks and reduces the abnormal processing that contributes to symptoms.

Other approaches are less practical for daily functioning. Fully occluding vision would be too disabling for activities like reading or driving, and occluding only the temporal fields can overly restrict useful vision and isn’t as targeted to the problem. No occlusion would leave the patient with the same level of visual overload. So, binasal occlusion offers a balanced way to reduce visual stress while preserving essential vision, making it the best fit for this condition.
