Idiopathic Intracranial Hypertension IIH is a disorder of elevated cerebrospinal fluid pressure due to the unknown cause. The signs and symptoms are normal mental status with no localizing neurologic findings, increased cerebrospinal fluid pressure (Non obese may have >200 mm H2o, in the obese may have > 250 mm H2o), fatigue, headache, loss of peripheral vision, nausea and vomiting, shoulder and neck pain, temporary blindness, tinnitus. IIH is a potentially blinding condition that results in papilledema from increased intracranial pressure. Interestingly, both IIH and glaucoma produce similar visual field defects. Diagnosis of diabetes also doubles the risk for developing glaucoma. If left untreated, glaucoma can seriously impair the vision, and cause partial or total blindness.
