[Choroidal calcification associated to chondrocalcinosis].

Introduction: Chondrocalcinosis is a common joint condition in people over 50, characterized by the deposition of calcium pyrophosphate crystals that causes calcification in cartilage structures. Although its prevalence in the general population is 5%, sclerochoroidal calcifications are a rare finding in this pathology.

Objective: Describe the case of a 60-year-old man with choroidal calcification in the left eye, associated with radiological findings of chondrocalcinosis, whose metabolic report showed parameters compatible with hyperparathyroidism.

Clinical Case: Male patient from Mexico City, smoker for 45 years, with medical history of calcium pyrophosphate deposition disease at age 16, attended routine eye examination. A left eye funduscopy revealed an irregularly shaped white-yellowish subretinal lesion with well-defined edges inside the upper temporal arch. Ophthalmological paraclinical studies were performed, and a choroidal hyperreflectic paramacular plate image, which did not involve the retina layers, was corroborated with five-line optical coherence tomography.

Conclusions: Although the lesions are asymptomatic and do not require treatment, it is of great importance to make a differential diagnosis with choroidal metastases, choroidal melanoma, choroidal osteoma and lymphoma, since these pathologies do require more aggressive treatment.
