PURPOSE: To present a case with bilateral choroidal neovascularization (CNV) secondary to acute disseminated encephalomyelitis-associated choroiditis requiring immunomodulatory therapy for prevention of recurrence. METHODS: The clinical course of a patient diagnosed with acute disseminated encephalomyelitis, who developed bilateral choroiditis at the time of his neurologic diagnosis and bilateral CNV 6 years later, is reviewed. PATIENT: A 57-year-old man developed CNV in both eyes, 6 years after the initial diagnosis of acute disseminated encephalomyelitis-associated choroiditis. The patient was initially treated successfully with intravitreal bevacizumab injections and oral prednisone, but CNV recurred with steroid tapering. Mycophenolate mofetil was initiated as steroid-sparing immunomodulatory therapy. RESULTS: There was no CNV recurrence for 1.5 years without the need for additional antiangiogenic therapy. CONCLUSION: To our best knowledge, this is the first report of choroiditis and secondary CNV associated with acute disseminated encephalomyelitis. In cases of recurrent CNV associated with choroiditis, systemic therapy should be strongly considered in conjunction with antiangiogenic therapy. The recurrence of CNV with tapering of oral steroids and the remission of CNV with steroid-sparing immunomodulatory therapy support the role of ongoing inflammation in the pathogenesis.
