Fundus photograph of the left eye in (A) 2006 and (B) 2012. (A) Fundus photographs showing yellow-white calcified choroidal osteoma (arrowheads) of approximately four disc diameters in size, accompanied by a white decalcified region in the center of the tumor. There are tumor vessels (arrows), designated spider vessels, around the decalcified region. (B) The calcified regions (arrowheads) are obviously smaller and the decalcified region is wider than that observed in 2006.. Note: The retinal vessels are compressed due to the decalcified choroidal osteoma (square box).

Ophthalmoscopy and fundus photograph examination revealed yellow-white lesions of approximately 4 disc diameters in size in OS (Figure 1A). Ophthalmoscopy and fundus photograph examination revealed yellow-white lesions of approximately three disc diameters in size in OS, and this calcified region was more contractive than those found during the first examination (Figure 1). Her best-corrected visual acuity was 20/400 in OS (Figure 1).
Spectral-domain optical coherence tomography scans of the left eye. (A) Longitudinal scan of the tumor. The round hyper-reflective mass accompanied by serous retinal detachment and disappearing posterior optical shadowing projected strongly upward from the choroid and partially broke through into the retina. Note the lamellar reflective pattern in the subretina and the disorganized structure of the retina with loss of inner and outer retinal layers. (B) Longitudinal scan of the tumor. There is a curved hyper-reflective mass similar to the finding in (A). (C) Skewed scan of the tumor. The raised hyper-reflective mass, a mound-like area, is observed in decalcified regions. (D) Fundus photograph for scan marking.

In 2012, SD-OCT (Spectralis, Heidelberg Engineering, Heidelberg, Germany) revealed a layered hyper-reflective pattern, which was lamellar in appearance, and had a hyper-reflective mass pattern forming a mound-like area (Figure 2). Decalcified regions of the choroidal osteoma were raised and partially spread into the retina causing serous retinal detachment (Figure 2).
