23 old male is complaining from a black spot on visual field in one eye, normal mri, normal fundus and normal intracranial pressure. What can be this?

High or low?: Low CSF pressure is treated differently than high. Treat the underlying cause (eg CSF leak following lumbar puncture) Raised ICP if due to an imbalance of CSF production vs resorption is typically treated with carbonic anhydrase inhibitors like Zonegran, Topamax or Diamox. Rarely is surgery (optic nerve fenestration or shunting done unless the increased ICP is due to a blockage of CSF flow ...Read moreSee 1 more doctor answer
