Abstract

Background

Choroidal neovascularization (CNV) is a rare complication of intermediate uveitis. Risk factors are not well-characterized. Here, we describe a case of peripapillary CNV in a patient with intermediate uveitis and explore the pathophysiology and treatment of this condition. This study is a case report and review of the literature.

Results

A 15-year-old boy with intermediate uveitis - suppressed for the preceding year on immunosuppressive therapy and low-dose corticosteroids - and chronic disc swelling presented with unilateral metamorphopsia, peripapillary subretinal hemorrhage, and subretinal fluid. Fluorescein angiogram confirmed the presence of an active choroidal neovascular membrane. Treatment with intravitreal bevacizumab 1.25 mg every 4 weeks for 4 months resulted in resolution of subretinal fluid, subretinal hemorrhage, and regression of the CNV. The patient's intermediate uveitis remained inactive throughout this time.

Conclusion

Review of the existing literature and pathophysiologic consideration suggests that chronic disc edema may be a risk factor for this condition. Peripapillary CNV in the context of intermediate uveitis appears to respond well to VEGF-inhibitor therapy.
