Long-Term Sequelae of Optic Nerve Encasement with Fibrous Dysplasia: Is Prophylactic Nerve Decompression Indicated?

Fibrous dysplasia (FD) is an expansile bone disorder that involves the anterior cranial base and may encase the optic canal. Surgeons have assumed that radiographic encasement results in optic canal constriction with blindness and recommend prophylactic optic nerve decompression despite risks. Our previous cross-sectional analysis showed no correlation between canal constriction and visual disturbances. However, the long-term sequalae of optic nerve FD encasement is unknown. Aim: to correlate the long-term vision and optic canal caliber in patients with FD.
