Purpose: Approach to loss of visual acuity in a patient with a choroidal osteoma (CO) which had been stable for seven years.
Methods: Fluorescence angiography confirmed a choroidal neovascularization (CNV) as the cause of the loss of visual acuity. Treatment with intravitreal (IVT) injection of ranibizumab.
Results: Increase of visual acuity and decrease of edema after IVT injection.
Conclusion: Monitoring is necessary even for primarily benign CO in order to detect secondary complications causing loss of visual acuity, e. g. secondary CNV. Anti-VEGF IVT represents an approved treatment option.
