Purpose: To detect the vessel density of choriocapillaris (CC) vascular network in eyes affected by choroidal osteoma and in eyes complicated by macular neovascularization (MNV), using optical coherence tomography angiography (OCTA).
Methods: In this retrospective study, twenty-eight eyes of 28 patients were divided into three groups: group 1 including patients with calcified choroidal osteoma, group 2 including patients with decalcified choroidal osteoma, and group 3 including patients with decalcified choroidal osteoma complicated by MNV. OCTA analyzed the vessel density of CC in these lesions localized in the peripapillary region.
Results: We enrolled 12 eyes with calcified choroidal osteoma, 11 eyes with decalcified choroidal osteoma, and 5 eyes with decalcified choroidal osteoma complicated by MNV. The eyes with decalcified choroidal osteoma and MNV revealed a statistically significant reduction in vessel density of the CC respect to the other groups (p < 0.001). Moreover, the vessel density of CC in decalcified choroidal osteoma was significantly reduced compared to calcified choroidal osteoma (p < 0.001).
Conclusions: OCTA allowed a quantitative evaluation of choriocapillaris vessel density in choroidal osteoma, in order to detect the changes of this vascular network, which could lead to the development of MNV. Therefore, OCTA could be a new diagnostic tool in the clinical management of the choroidal osteoma.

The aim of the study was todescribe the clinical features, optical coherence tomography (OCT) and fundus autofluorescence (FAF) imaging in patients with choroidal and retinal tumors. Ninety eyes of 89 patients with treatment-naive macular, midperipheral, and juxtapapillary choroidal and retinal tumors were retrospectively included in the study. All patients underwent a complete ophthalmic examination, B-mode ultrasonography, OCT, and FAF imaging.

Choroidal osteoma is a rare, benign, osseous choristoma presenting as an orange-yellow, well-defined fundus mass. It presents unilaterally in most cases, has a predilection for the female sex, and favor a juxtapapillary location, becoming clinically manifest when it involves the macula. Almost 60% of eyes with osteoma may suffer significant visual loss.
