[Clinical case of the month. Bilateral optic neuropathy secondary to biphosphonate therapy].

Ocular side effects associated with biphosphonates have been described. Conjunctivitis, uveitis and scleritis are the most common adverse events. We report a case of bilateral toxic optic neuropathy with optic dies edema occurring soon after a pamidronate intravenous infusion in a patient who previously presented both a conjunctivitis and an uveitis of moderate intensity associated with alendronate therapy.
