Optic nerve cyst-like formation presenting as a delayed complication of optic nerve sheath fenestration.
Overview
abstract
Two patients with idiopathic intracranial hypertension underwent optic nerve sheath fenestration. One patient developed decreased vision and choroidal folds 1 month postoperatively. The other patient developed proptosis and pain 9 months postoperatively. Neuroimaging showed a cyst-like structure adjacent to the optic nerve in each patient. In each case, symptoms and signs resolved after surgical excision of the structure.
