Abstract
- 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.
