title: Internal ophthalmoplegia following inferior oblique myectomy: a report of three cases.
abstract: Three patients are reported in whom paralysis of accommodation and mydriasis (internal ophthalmoplegia) developed following inferior oblique myectomy. In all three patients, accommodation eventually returned to normal; in two, mild anisocoria persisted; in one patient, pupillotonia was noted after 2 1/2 years. The mechanism of this previously unreported surgical complication is thought to be excessive stretching of the nerve to the inferior oblique muscle with secondary trauma to the ciliary ganglion.
