Purpose
The primary objective was to document change in postoperative marginal reflex distance-1 (MRD1) after Müller muscle conjunctival resection (MMCR) surgery. The secondary objective was to identify predictors of change in postoperative MRD1.
Methods
A multicenter prospective cohort study was performed on patients consecutively recruited for MMCR. MRD1 was measured immediately after MMCR, at the 1-week postoperative visit, and the ≥ 3-month postoperative visit. MRD1 at the immediate and 1-week timepoints were compared with MRD1 ≥ 3-months using descriptive statistics. Predictors of change in MRD1 were analyzed using multivariate regression analysis.
Results
A total of 150 patients (226 eyelids) were included. Regarding the immediate to ≥ 3- month interval, 53.8% of eyelids remained clinically similar (rise or fall ≤ 0.5mm), 19.8% rose ≥ 1mm, and 26.4% fell ≥ 1mm. Regarding the 1-week to ≥ 3-month interval, 76.5% remained clinically similar, 17.3% rose ≥ 1mm, and 6.2% fell ≥ 1mm. No variable predicted change in MRD1 over either interval with both clinical and statistical significance.
Conclusion
Immediate postoperative MRD1 is likely to reflect the late result in only 54% of cases. However,1-week postoperative MRD1 is similar to the late result in 77% of cases, and is highly unlikely (6%) to fall by the final visit. No variable significantly impacts change in postoperative MRD1.
