Abstract
To determine the changes in the lower eyelid position, following ptosis surgery of the upper eyelid of the same eye in blepharoptosis patients. 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. 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). Present study showed a significant improvement in the condition of the lower eyelid improved after upper eyelid ptosis surgery.
