Bariatric surgery is an effective treatment for IIH in morbidly obese patients, resulting in high rates of symptom and papilledema resolution.
For morbidly obese IIH patients who struggle with lifestyle changes, bariatric surgery is a highly effective option. It leads to the resolution of symptoms and papilledema in the vast majority of cases. Discuss this with your neuro-ophthalmologist if other treatments fail.
ModerateSupportsMEDIUM confidence
Of the patients for whom data were available, 92% had resolution of IIH symptoms, 97% had resolution of papilledema, and 92% had complete or nearly complete resolution of visual field deficits.
Why this rating
