Osseous tumors of the uveal tract are relatively rare, benign lesions. Choroidal osteomas usually occur in the region of the posterior pole, typically in younger females, and are more often unilateral than bilateral. Because of their location, they are often associated with significant secondary vision loss, e.g., due to associated choroidal neovascularisation or overlying photoreceptor drop-out. Sclerochoroidal calcification, in contrast, is usually bilateral, found in older patients, and not associated with significant vision loss. This chapter describes the key differential diagnostic features, including ultrasound, angiographic, and OCT imaging findings in these lesions.
