title: Retrobulbar optic neuritis after pamidronate administration in a patient with a history of cutaneous porphyria.
abstract: We describe the case of a patient who developed reversible retrobulbar optic neuritis after intravenous pamidronate therapy for established osteoporosis. This possible complication has never been previously reported and, since our patient had a history of porphyria, it suggests that bisphosphonates should be administered cautiously in patients with this disease.
