Lower eyelid position after ptosis repair in patients with blepharoptosis

Abstract

PURPOSE: To determine the changes in the lower eyelid position, following ptosis surgery of the upper eyelid of the same eye in blepharoptosis patients. METHODS: This prospective interventional before and after study included patients aged more than 5 years with blepharoptosis. Margin reflex distance one (MRD-1), MRD two (MRD-2), and levator function were measured before and the 6 months after the surgery. RESULTS: Sixty patients with blepharoptosis (33 congenital and 27 acquired) were recruited. The mean age was 21.61 +/- 10.82 and 59.8 +/- 13.73 years in congenital and acquired groups, respectively. The mean MRD-1 improved from 1.95 +/- 0.99 before treatment to 4.47 +/- 0.47 after treatment (p < 0.001). The mean MRD-2 improved from 5.57 +/- 0.63 before treatment to 4.95 +/- 0.51 after treatment (p < 0.001). There was no statistically significant difference in MRD-1 and MRD-2 changes between the two groups (p > 0.05) There was no statistically significant correlation between MRD-2 changes and LF (r = -0.03. p = 0.83). CONCLUSION: Present study showed a significant improvement in the condition of the lower eyelid improved after upper eyelid ptosis surgery.
