Post Trauma Vision Syndrome can be addressed with which prism configuration to reduce symptoms (a commonly cited approach)?

• A. Base In Prism
• B. Base Out Prism
• C. No prism should be used
• D. Prism must be avoided altogether

Answer: (A)

A common approach in Post Trauma Vision Syndrome is to use base-in prisms. In this condition, the brain often has difficulty coordinating vergence after a brain injury, especially during near tasks, which leads to symptoms like headaches, eyestrain, and diplopia. Placing small base-in prisms shifts the visual input in a way that reduces the vergence effort the eyes must exert to fuse images at near. By decreasing the required convergence or divergence, symptoms are often alleviated and comfortable binocularity is improved. Using base-out prisms would increase vergence demand and could worsen symptoms, and opting against prisms misses a practical, symptom-relief option commonly cited in this context.
