The authors report spectral-domain optical coherence tomography (SD-OCT) findings in a patient with decalcifying choroidal osteoma accompanied by a choroidal neovascular membrane and serous retinal detachment. A 13-year-old girl was found to have a choroidal osteoma in the left eye. The clinical diagnosis was confirmed by B-scan ultrasonography, computed tomography, and fluorescein and indocyanine green angiography. The SD-OCT findings over the decalcified portion included serous retinal detachment, photoreceptor outer segment disorganization, retinal pigment epithelial atrophy, deformed Bruch's membrane, and choroidal neovascular membrane. In contrast, the retinal structures over the calcified portion appeared to be preserved. SD-OCT showed loss of a vascular appearance and increased thickness in the affected choroid, especially in the decalcified portion. Choroidal thickening may be associated not only with choroidal osteomas, but also with tumor decalcification. These unique features on SD-OCT may be important in understanding poor visual prognosis when decalcification involves the fovea.
