Long-term results of intravitreal ranibizumab for osteoma-related choroidal neovascularization in a child.

Though choroidal osteoma is a rare benign tumor, associated choroidal neovascularization (CNV) can be a cause of severe visual loss. A nine-year-old boy presented with one-month history of decreased vision in left eye. Upon a complete ophthalmologic examination, including fundus fluorescein angiography and optical coherence tomography, he was diagnosed with choroidal osteoma-related subfoveal CNV in the left eye. The CNV was associated with subretinal hemorrhage, subretinal fluid, and cystoid macular edema. Owing to the young age and subfoveal localization of the CNV, intravitreal ranibizumab injection was performed on this patient after a detailed discussion with the parents of its safety profile. No local or systemic complications were noted. No recurrence of CNV lesion was noted during 30 months of follow-up, and the vision was maintained. This report shows the favorable outcome of intravitreal injection of ranibizumab in choroidal osteoma-related CNV in a child.
