Choroidal calcification is an uncommon benign lesion occurring in predominantly elderly. This condition is ordinarily idiopathic. However, it can be caused by phosphocalcic metabolism disorders. We report the case of a 72-year-old woman followed-up in the ophthalmology department for proliferative diabetic retinopathy who was found to have a bilateral yellowish lesion in the fundus during a routine eye examination corresponding to a choroidal calcification. Metabolic analyses led to the diagnosis of primary hyperparathyroidism. Choroidal calcifications warrant a systemic evaluation to identify a potential underlying disease.
