Abstract
Purpose
Comparing the surgical and refractive outcomes of congenital ptosis repair by different surgical techniques.
Methods
This longitudinal cohort study reviewed medical records of 101 patients who underwent congenital ptosis repair, from 2006 to 2022 in a single center. Analysis was performed for demographic background, co-morbidities, pre-operative and post-operative ocular examinations and refraction, complications, reoperations, and success rates.
Results
Following exclusion criteria, we remained with 80 patients (103 eyes) who underwent either frontalis muscle suspension surgery (FMS) (55 eyes) or levator muscle surgery (LM) (48 eyes). Patients in the FMS group were younger (mean age of 3.1 vs. 6.0 years, p < 0.001) and had worse pre-operative ocular assessments including prevalence of visual axis involvement, chin-up head position, ptosis severity, and levator muscle function (LF) (p < 0.001). Both groups had a 25% rate of reoperation, however while in the LM group reoperation was required solely due to undercorrection, in the FMS group various indications prompted reoperation. Success rate was higher in the FMS group (87.3% vs. 60.4%, p = 0.002). While pre-operative astigmatism was higher in the LM group (p = 0.019), no significant differences were observed post-operatively. Spherical and spherical equivalent changes over time were significant only in the FMS group (p = 0.010 and p = 0.004, respectively).
Conclusions
Within our cohort, a higher success rate of congenital ptosis repair was observed among patients who underwent FMS compared to LM, despite similar reoperation rates. In cases of severe ptosis and moderate LF, LM demonstrated a lower-than-anticipated success rate. Astigmatic changes following ptosis repair were not consistent in either group.
