Sclerochoroidal calcification

We studied 19 patients with sclerochoroidal calcification. The findings were bilateral in 16 patients and unilateral in the remaining three patients. The lesions, which were usually multifocal, had two characteristic appearances, plaque-like and tumorlike. Eleven patients had relatively flat, irregularly shaped, plaque-like, yellow-white lesions located between the arcades and the equator. Eight patients had more elevated tumorlike lesions, ranging up to 6 mm in height. All showed patterns on echography consistent with calcification. The calcification was often documented in both the choroid and sclera; sometimes it appeared only in the choroid, but never only in the sclera. Calcium metabolism appeared to be normal in all but two of the nine patients in whom it was investigated. Idiopathic sclerochoroidal calcification has a characteristic echographic and ophthalmoscopic appearance and may be more common than has been realized.
