Photodynamic therapy for unilateral idiopathic peripapillary choroidal neovascularization in a child.

A 10-year-old girl presented with visual loss in her right eye. Best-corrected visual acuity was 20/50 in the right eye and 20/20 in the left eye. Dilated funduscopic examination revealed a yellowish elevated lesion near the optic disc with macular edema and hemorrhage on the inferotemporal vascular arcade in the right eye. Fluorescein angiography showed a hyperfluorescent lesion consistent with choroidal neovascularization (CNV) and optical coherence tomography (OCT) showed a peripapillary lesion with subretinal fluid elevating the neurosensory retina in the macular area. With a diagnosis of unilateral idiopathic peripapillary CNV, the patient underwent photodynamic therapy (PDT) with verteporfin. At the four month follow-up, visual acuity increased to 20/25 and OCT showed peripapillary scar formation and total resolution of the subretinal fluid. At the one year follow-up, visual acuity and fundus were stable without recurrence of the lesion. PDT for peripapillary CNV in children has not previously been reported. Although it seems to be a favorable treatment option for peripapillary lesions, there is a lack of knowledge about long-term follow-up in pediatric cases.
