Purpose: To describe a case of choroidal osteoma with choroidal neovascularization (CNV) that was successfully treated with two intravitreal injections of bevacizumab (IVB).
Design and methods: Case report on a 12-year-old Japanese girl who presented with a sudden decrease in vision in her left eye. At the first visit, 2 days after the onset of her symptoms, her visual acuity (VA) in her left eye was 0.2. Ophthalmoscopy showed a hemorrhage of 5 disc diameters under the retinal pigment epithelium and a serous retinal detachment at the posterior pole of the left eye. These findings were confirmed by optical coherence tomography. Fluorescein angiography (FA) and indocyanine green angiography (ICGA) showed several points of leakage around the fovea, which suggested a CNV. From these findings, the patient was diagnosed with choroidal osteoma with a CNV. The submacular hemorrhage was from the CNV associated with the choroidal osteoma. We treated her with two injections of 1.25 mg/0.05 mL IVB with a 4-month interval.
Results: The patient's VA in her left eye improved to 0.7, and this vision was maintained for 4 years. The CNV disappeared in the FA and ICGA images and no recurrence was observed after 4 years.
Conclusion: Our findings indicate that IVB is effective in resolving CNV in eyes with an osteoma and prevents a decrease of vision in eyes with a choroidal osteoma with a CNV.
