Idiopathic sclerochoroidal calcification.
OBJECTIVE
Sclerochoroidal calcification is a rare ocular condition characterized by multifocal, yellow-white elevated fundus lesions typically located in the superotemporal quadrant along the superior arcades. The pathology of calcification can be classified as dystrophic, metastatic, or idiopathic. Vision-threatening complications may arise, such as choroidal neovascular membrane and serous retinal detachment. The pathogenesis of sclerochoroidal calcification remains unclear.


METHODS
A 72-year-old Caucasian male patient presented to the clinic for routine examination. Fundus evaluation revealed bilateral, multifocal, pale yellow elevated lesions in the superotemporal fundus. Ultrasonography showed a focal area of hyper-reflectivity located in the posterior retina of both eyes, and optical coherence tomography showed an intact retina overlying the elevated lesions in the choroid. Systemic evaluation for dystrophic and metastatic calcification was negative, and the patient was diagnosed with idiopathic sclerochoroidal calcification.


CONCLUSIONS
It is important to distinguish sclerochoroidal calcification from other conditions to prevent unnecessary intervention. Calcification of body tissues warrants a systemic evaluation, including screening for calcium and phosphorous levels, to rule out underlying systemic disease. If a biochemical abnormality is discovered, it can be appropriately treated with supplements. If calcification is deemed idiopathic, then annual dilated examinations are recommended to monitor the fundus lesions. Visual prognosis for sclerochoroidal classification is good, as the lesions are typically located away from the macula and foveal encroachment is rare.
