Background: The success rates of conjunctiva-Müller muscle resection vary in reports of previous studies, with 81% to 88.6% success rates having been reported in other countries. Few studies have reported on the surgical success rates of conjunctiva-Müller muscle resection in Korea compared to the number of reports on other methods of blepharoptosis repair. We therefore sought to determine the clinical efficacy and success rate of conjunctiva-Müller muscle resection in patients with mild blepharoptosis and identify the factors that affect the surgical success rate.
Objective: This study was performed to evaluate of the clinical efficacy and success rate of conjunctiva-Müller muscle resection (posterior approach technique) in patients with mild blepharoptosis and to identify the factors that affect its surgical success rate.
Methods: Surgeries were performed by one surgeon in 30 patients (35 eyes) and only when the marginal reflex distance 1 (MRD1) increased over 1 mm at 5 minutes after the administration of 0.25% phenylephrine eye drops. The MRD1, MRD2, Brow-pupil distance (BPD), and interpalpebral fissure (IPF) were measured pre-operatively, 1 month post-operatively, and at the final follow-up visit.
Results: The mean MRD1 increased significantly from 0.83±0.96 mm pre-operatively to 2.45±0.77 mm post-operatively (p=0.012). The mean IPF also increased significantly from 5.54±2.04 mm pre-operatively to 7.62±1.85 mm post-operatively (p=0.003). The mean BPD, however, did not change significantly (22.94±4.96 mm pre-operatively and 23.19±5.72 mm post-operatively, p=0.863). The post-operative MRD1 for the eye with blepharoptosis was less than 1 mm compared to that for the opposite eye.
Conclusion: Conjunctiva-Müller muscle resection is a safe and effective surgical method in patients with mild or moderate blepharoptosis with good levator palpebrae muscle function in which the post-operative results can be predicted on the basis of the amount of muscle resection.
