Advanced diagnostic testing enables a physician to accurately determine if you have an elevated intracranial pressure (ICP) while looking for evidence of brain tumors, venous clots or other neurological conditions with similar symptoms. Early diagnoses of IIH are critical to prevent loss of vision and minimise IIH symptoms using medications, lifestyle changes and in some cases surgery. Because the diagnosis and subsequent treatment of IIH involve both neurologists and neuro-ophthalmologists, the best possible long-term outcomes and improved quality of life can be achieved through a multidisciplinary approach.
