Abstract
The purpose of this study was to find out the etiological pattern of blepharoptosis among patients presenting in BPKLCOS, T.U. Teaching Hospital. This was a hospital based descriptive and cross-sectional study conducted from February 2003 to July 2004. A total of 125 patients with ptosis were evaluated. 78 cases (62.4%) were congenital and 47 cases (37.6 %) were acquired. Congenital simple ptosis and congenital complicated ptosis comprised of 58% and 42% respectively. Among the acquired cause, ptosis due to trauma was the commonest 32%, followed by third cranial nerve palsy 25.5%, myasthenia gravis 17%, aponeurotic 10.7%, chronic progressive external ophthalmoplegia 8.5% etc. Aetiology-wise, myogenic ptosis was the commonest (65.6%) which was followed by neurogenic (16.8%), traumatic (12%) and aponeurotic ptosis (5.6%). Congenital ptosis is more common than acquired ptosis. Myogenic ptosis is the most predominant type of ptosis. Among the congenital ptosis, congenital simple ptosis is more common than congenital complicated ptosis. Among the acquired cases trauma, third cranial nerve palsy and myasthenia gravis are the major attendees.
