Five Cases of Orbital Infarction Syndrome Caused by Compression of Surgical Scalp Flap / 대한뇌혈관외과학회지

ABSTRACT

Orbital infarction syndrome 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 proptosis, ophthalmoplegia, and unilateral blindness. We recently experienced 5 cases of proptosis, ophthalmoplegia and unilateral blindness immediately after operation for 2 years. The cause of orbital infarction syndrome in these cases appeared to be the direct compression of orbit by the tightly retracted frontal scalp flap. We report and discuss possible mechanism with literature review.
