Abstract
- Global orbital infarction is a rare disorder resulting from ischemia of the intraocular and intraorbital structures due to hypoperfusion of the ophthalmic artery and its branches. The syndrome can occur with common carotid artery occlusion, orbital mucormycosis, giant cell arteritis and complications of surgery and manifests protosis, ophthalmoplegia, and blindness. Protrusion of the eyeball(proptosis) is the result of expansion of tissue within orbital cavity and is the hallmark of orbital diseases. Expansion lesions may be benign or malignant and may arise from bone, muscle, nerve, blood vessel, or connective tissue. We report a case of combined ophthalmic artery occlusion, optic neuropathy, and third nerve palsy involving pupil in a 32-year-old patient with unilateral idiopathic proptosis following anterior choroidal aneurysm operation, and discuss possible mechanism with literature review.
