Abstract
SA.09.03 Sclerochoroidal calcification Willerding G., Bechrakis N. E., Wachtlin J., Krause L., Foerster M. H.
Augenklinik, Charité Universitätsmedizin, Campus Benjamin Franklin, Berlin Objective: To describe sclerochoroidal calcification as an uncommon ocular condition with usually bilateral, characteristic fundus lesions and occasionally an association with an altered electrolyte metabolism.
Methods: Case series including patients diagnosed as having sclerochoroidal calcification based on ophthalmoscopy and ultrasonography. Angiographic findings, OCT and systemic evaluation were also performed.
Results: 8 patients (mean age, 72 years) presented with subretinal, asymptomatic yellow -white, mid-peripheral fundus lesions. B-scan ultrasonography revealed dense echoes with orbital shadowing. Referral diagnosis was idiopathic sclerochoroidal calcification in only one case. Other referral diagnoses included metastasis, melanoma, osteoma, and unknown mass. One patient met the diagnostic criteria of Gitelman syndrome (familial hypomagnesemia). Additional diagnoses were Lupus erythematodes in one and diabetic retinopathy treated with panretinal lasercoagulation in another patient.
Conclusions: Sclerochoroidal calcification may mimic choroidal metastasis, melanoma, osteoma or granulomatious lesions in older patients. Ophthalmoscopy and ultrasonography aid in correct diagnosis and distinction from other, especially malignant conditions. The patients may be tested for underlying disorders of calcium-phosphorus metabolism that can lead to abnormal calcium deposition.
