Extensive concomitant optic nerve sheath and sclerochoroidal calcifications

Abstract

Computed tomography revealed tram track–like calcifications within bilateral optic nerve sheaths and large, amorphous calcific plaques on the sclera of a 91-year-old man (Fig. 1). His past medical history was significant for calcium pyrophosphate dihydrate deposition disease, chronic renal failure, and hypothyroidism. To the best of our knowledge, there is only 1 reported case describing concomitant optic nerve sheath and sclerochoroidal calcifications that were idiopathic.1 Disorders of calcium-phosphorus homeostasis are another known etiology of these calcifications.
