Abstract
Sclerochoroidal calcifications (SC) are a rare and benign ocular condition characterized by yellow-white irregular subretinal lesions usually found in the supero-temporal arcade of the midperipheral fundus in middle-aged elderly men. We present a clinical case of a 79- year-old patient who during a fundus examination presented raised whitish nodules in the supero-temporal arcade in the right eye. After performing optical coherence tomography, ultrasound, ocular computed tomography and laboratory analysis, she was diagnosed with idiopathic sclerochoroidal calcifications The pathogenesis of [...]
Highlights
Idiopathic sclerochoroidal calcifications (SC) are commonly found in white men between 50 and 80 years of age
Described as yellowish-white plaques located in the supero-temporal arcade in the mid-peripheral retina, under retinal layers, in both eyes
Autofluorescence and the appearance of the lesion with ultrasound and tomography are useful for its diagnosis.(4) These plaques may simulate tumors (1,2) and can lead to misdiagnosis especially with choroidal osteomas.(4) Metastases, amelanotic melanomas, nevus, idiopathic choroiditis or intraocular lymphomas(1,5) should be excluded. This process can be associated with systemic metabolic disorders in relation to abnormal calcium-phosphorus metabolism or renal tubular syndromes with hypokalemic metabolic alkalosis.(6) It is a diagnosis of exclusion, it is important to study these electrolyte disorders.

We performed haematological and hormonal studies where the first determination of PTH was 87.36 pg / ml (normal limits between), with total calcium of 9.9 mg / l
