A case of Orbital Infarction Syndrome Caused by Compression of Bulky Bicoronal Scalp Flap

ABSTRACT

PURPOSE: To report a case of orbital infarction syndrome induced by compression due to hard and bulky scalp flap. METHODS: Subject and METHODS: A 27-year-old female presented to our clinic, complaining of orbital pain, proptosis, ptosis, ophthalmoplegia and unilateral blindness, immediately after removal of cavernous hemangioma induced by the radiotherapy at 7 years earlier in right frontal lobe. Her scalp was hard and thick due to previous scar change and radiotherapy. Ophthalmologic examination demonstrated optic nerve injury, cranial nerve III, IV and VI palsy, diffuse retinal edema and cherry red spot in macula. Brain CT and MR angiography were done to evaluate the cause of orbital infarction. RESULTS: The cause of orbital infarction syndrome in this case appeared to be the compression of orbit by the hard and bulky scalp flap, and blindness was caused by the ischemia of intraorbital and intraocular structure.
