ABSTRACT
Eyelid retraction occurs secondary to various disease entities. To our knowledge, there has not been any report on the etiology of eyelid retraction in Korea. The authors have observed 47 patients with unilateral or bilateral eyelid retraction and studied the etiologies. Eyelid retractions were commonly associated with thyroid ophthalmopathy, traurna and neuropathic causes in adults, and paradoxic synkinesis of levator palpebrae muscle and thyroid ophthalmopathy in children. Unilateral eyelid retractions were most commonly associated with neuropathic causes, and thyroid ophthalmopathy is the most common cause in bilateral eyelid retractions. In contrary to the previous reports, lower lid retraction was characteristically more common than upper lid retraction in thyroid.
