To examine the influence of epinephrine contained in local anesthetic on upper eyelid height in transconjunctival aponeurotic repair for aponeurotic blepharoptosis. This retrospective study included 164 eyelids from 94 patients with aponeurotic blepharoptosis. Patients were divided according to the use of local anesthetic with (group A, n = 108) or without 1:100000 epinephrine (group B, n = 56). Margin reflex distance-1 (MRD-1) was measured before and after local anesthesia, and before, during, and 3 months after surgery. Change in MRD-1a (∆MRD-1a) was calculated by subtracting the postanesthetic MRD-1 value from the preanesthetic value, and we defined ∆MRD-1b by subtracting the postoperative 3-month MRD-1 value from the intraoperative value. ∆MRD-1a was positive in group A (0.57 ± 0.63 mm) and negative in group B (- 0.50 ± 0.45 mm; p < 0.001). Postoperative MRD-1 decreased significantly from intraoperative MRD-1 in group A (P < 0.001), although there was no significant difference between intraoperative and postoperative MRD-1 in group B (p = 0.255). The magnitude of ∆MRD-1b in group A (- 0.86 ± 0.63) was larger than that in group B (- 0.23 ± 0.26; p < 0.001). Epinephrine stimulates Müller's muscle during surgery, which leads to postoperative upper eyelid droop after the disappearance of the epinephrine effect. Using local anesthetics without epinephrine may allow more accurate estimation of postoperative eyelid height in transconjunctival aponeurotic repair.
