Bilateral Idiopathic Sclerochoroidal Calcification: A Case Report

Sclerochoroidal calcification (SCC) is a rare and often asymptomatic condition characterized by the deposition of calcium pyrophosphate in the sclera and choroid. It predominantly affects elderly individuals of Caucasian descent and is most often idiopathic, although it can be secondary to systemic disorders such as hyperparathyroidism or chronic renal disease. The lesions appear as irregular, white-yellow plaques located in the mid-periphery, typically along the vascular arcades. We present the case of an 80-year-old patient with bilateral idiopathic SCC, incidentally discovered during an ophthalmologic examination. The patient's medical history included diabetes, hypertension, and cataract surgery, and there was no history of high myopia or uveitis. Fundus examination revealed yellowish choroidal lesions bilaterally, confirmed by autofluorescence and optical coherence tomography (OCT) imaging as elevated sclerochoroidal plaques. Comprehensive systemic and laboratory evaluations excluded underlying metabolic or renal abnormalities, confirming the idiopathic nature of the calcifications. The patient remained asymptomatic, and no treatment was required. This case underscores the importance of considering SCC in the differential diagnosis of elevated choroidal lesions. It highlights the need for thorough systemic evaluations to exclude secondary causes and emphasizes the generally benign prognosis of idiopathic cases.
