From these findings, we diagnosed this tumor as a choroidal osteoma.
In our case, the clinical feature of the tumor was atypical for all differential diagnoses, including choroidal osteoma and amelanotic malignant melanoma, so it was extremely challenging to make a clinical diagnosis as choroidal osteoma using conventional noninvasive examinations.
The histopathological finding of the choroidal osteoma from the living eye is extremely rare, because the morphological confirmation was typically performed after enucleation of the eye.
In conclusion, we must keep in mind that choroidal osteoma can be one of the differential diagnoses for atypical dome-shaped yellowish choroidal tumor.
Morbidity in choroidal osteoma is a consequence of SRF accumulation, haemorrhage from choroidal neovascularisation, or degeneration of the overlying RPE or sensory retina.
Treatment options for foveal choroidal osteoma are limited (PDT is a reasonable choice in the case of extrafoveal lesions).
To conclude, choroidal osteoma is a rare benign ossifying tumour of the choroid.

Choroidal osteoma is a rare ossifying benign tumor with unknown pathogenesis.
Based on those findings, the patient was diagnosed with choroidal osteoma and secondary CNV.
The main causes of vision loss in choroidal osteoma are the development of CNV, subfoveal fluid, and photoreceptor degeneration.
