Medline ® Abstract for Reference 24

Disk swelling in patients with hypoparathyroidism has often been attributed to papilledema but rarely to optic neuritis. Although we are reporting a patient with hypoparathyroidism in whom optic neuritis developed, a causal relationship is not yet clear. The patient may have had ischemic optic neuropathy concomitant with hypoparathyroidism or caused by tetanic vasospasm or calcification of optic nerve nutrient vessels.
