Purpose: To evaluate the response to anti–vascular endothelial growth factor therapy for choroidal neovascularization secondary to choroidal osteoma using optical coherence tomography angiography. Methods: This retrospective study included four eyes of four females with choroidal osteoma complicated by choroidal neovascularization, treated with ranibizumab. All patients underwent full ophthalmologic examination, including ocular ultrasound, retinography, fluorescein angiography, spectral-domain or swept-source optical coherence tomography, and optical coherence tomography angiography. These images were analyzed to measure choroidal osteoma and to study choroidal neovascularization changes after intravitreal anti–vascular endothelial growth factor. Results: In all cases, fluorescein angiography revealed the presence the choroidal neovascularization, as an early hyperfluorescence area increasing during the exam. Optical coherence tomography showed both the choroidal osteoma and choroidal neovascularization and intra- or subretinal fluid as activity sign. In optical coherence tomography angiography, choroidal osteoma vessels were valuable in outer retina and choroidal slabs, and were irregular and did not change after ranibizumab injection; neovascular network correlating with choroidal neovascularization showed a hyperflow tangled vessels in outer retina, decreasing in density after anti–vascular endothelial growth factor therapy. Conclusion: Optical coherence tomography angiography seems to be a useful tool in visualizing and distinguishing vascular networks of choroidal osteoma and of choroidal neovascularization secondary to choroidal osteoma better than fluorescein angiography.
