Which management approach is used to reduce symptoms in Post Trauma Vision Syndrome?

• A. Base In Prism
• B. Scleral contact lens
• C. LASIK
• D. Vision therapy

Answer: (A)

Post trauma vision syndrome often involves inefficient or mismatched vergence and accommodation after brain injury, so reducing the visual system’s strain can provide quick symptom relief. Base-in prisms shift the perceived image in a way that lowers the required amount of convergence during near tasks, which directly eases diplopia, eye strain, and headaches that commonly accompany PTVS. This optical adjustment addresses the binocular load the damaged system is struggling with, making near work more comfortable while vision therapy can later retrain the oculomotor system if needed. Other options don’t target this binocular load as directly: scleral lenses and LASIK address refractive or surface issues rather than the vergence-demand reduction, and vision therapy is a broader rehabilitative approach rather than a specific immediate symptom-relief strategy.
