Choroidal osteoma secondary to chronic posterior scleritis: A case report and literature review

Choroidal osteoma is a rare benign ossifying tumor of the choroid. Posterior scleritis is an uncommon yet potentially sight-threatening inflammation of the sclera. Herein, we report a case of choroidal osteoma secondary to chronic posterior scleritis accompanied by a literature review. Decalcification of the tumor, choroidal neovascularization, and retinal pigment epithelium atrophy can result in blindness. Hence, patients with recurrent posterior scleritis need long-term follow-up; in addition, we need to be alert for complications, such as choroidal osteoma, which can ultimately lead to a poor visual prognosis.
