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.
