A 47-year-old female patient presented with a complaint of decreased vision in the right eye. Her visual acuity was 0.16 in the right eye and 1.0 in the left eye. Fundus examination revealed a slightly elevated, yellowish-white lesion with regular borders at the macula of the right eye. Early and late hyperfluorescence related with choroidal neovascularization (CNV) was detected in the right eye on fundus fluorescein angiography. B-scan ultrasonography revealed a hyperechoic choroidal lesion with acoustic shadowing. The lesion was diagnosed as choroidal osteoma. The patient received 3 injections of intravitreal ranibizumab. After 4 months, the visual acuity of the right eye was 0.9 and the CNV had regressed. Follow-up at about 7 months revealed reduced visual acuity in the right eye with an increase in subretinal fluid. An additional ranibizumab injection was administered. In this case report, we discuss the findings and treatment of a rare case of choroidal osteoma with secondary CNV.

A 15-year-old male patient admitted to our department with the complaint of painless blurring in the right eye in whom we diagnosed choroidal osteoma(CO). On examination, best corrected visual acuity (BCVA) was 20/100 in the right eye and 20/20 in the left eye. Fundus examination showed an orange-yellow, slightly elevated plaque with scalloped, well-defined margins in the posterior pole, consistent with a CO in the right eye. On fundus fluorescein angiography the lesion showed early patchy hyperfluorescence and late staining with no evidence of choroidal neovascular membrane. B-scan ultrasonography and orbital BT revealed findings consistent with CO. Optical coherence tomography (OCT) demonstrated subretinal fluid (SRF) of the macula in the right eye. For the treatment of SRF we suggested oral prednisolone theraphy (1mg/kg) for 10 days. One week later, complete resolution of SRF was seen on OCT, with improvement of BCVA to 20/20 in the right eye. The patient remained stable for 6 months after the treatment with a final BCVA of 20/20. [ABSTRACT FROM AUTHOR]

Choroidal osteoma is a rare benign osseous tumor typically found in healthy young women. The diagnosis of this tumor can be made clinically with characteristic findings of ultrasonography (USG), computerized tomography (CT) and angiography (FA). Enhanced depth imaging optical coherence tomography (EDI-OCT) has recently been used to evaluate the anatomical structure of the choroid and retina in choroidal osteoma. In this paper, we report a 13-year-old female case with choroidal osteoma. Ultrasonographic, angiographic, tomographic and EDI-OCT data of the patient are reviewed. [ABSTRACT FROM AUTHOR]

We report a case of bilateral choroidal osteoma and the accompanying OCT findings A 27-year-old woman presented to our clinic with a 5-year history of bilateral visual loss. The visual acuity of the patient was counting fingers at 1 m in the right eye and 0.2 in the left. On fundus examination of both eyes a peripapillary located mass was observed. This mass in the right eye was covering the macula with a white foveal part circumscribed by a yellow-orange halo; in the left eye it was covering the macula with a yellow-orange foveal part and white nasal part with an irregular surface. Choroidal osteoma was suspected. The diagnosis was confirmed by B scan ultrasonography, computer tomography, and fundus fluorescein angiography. The OCT findings were evaluated. Choroidal osteoma is a rare and benign ossifying tumor of the posterior pole of the eye that is typically seen in young women. Most commonly it occurs unilaterally. The diagnosis of this tumor, which may affect vision at different levels, can be made clinically and in combination with characteristic ultrasound and CT findings. Recently OCT has been used to evaluate the anatomical structure of the retina and choroid in choroidal osteoma. OCT is a useful method in choroidal osteoma to evaluate the anatomical structure of the retina and choroid and to identify the treatment protocol. [ABSTRACT FROM AUTHOR]
