Insights
This study found no link between eyelid lag after ptosis surgery and the improvement in eyelid height (MRD1). Immediate postoperative degrees of lagophthalmos (IPDL) cannot reliably predict ptosis correction outcomes.
Area of Science:
- Ophthalmology
- Surgical Research
- Clinical Outcomes
Background:
- Upper eyelid ptosis affects vision and aesthetics.
- Assessing surgical success in ptosis correction is crucial.
- Marginal reflex distance 1 (MRD1) is a key metric for ptosis assessment.
Purpose of the Study:
- To investigate the correlation between postoperative MRD1 improvement and immediate postoperative degrees of lagophthalmos (IPDL).
- To determine if IPDL can serve as a reliable indicator for successful ptosis treatment.
- To analyze factors influencing the variability and sustainability of ptosis correction outcomes.
Main Methods:
- Retrospective analysis of 19 patients (28 eyes) aged 1-11 undergoing ptosis surgery.
- Monitoring MRD1 for over six months postoperatively.
- Measuring IPDL immediately after surgery.
Main Results:
- No statistically significant correlation was found between MRD1 improvement and IPDL.
- Postoperative ptosis improvement showed variability and was not consistently sustained.
- Results indicate IPDL is not a reliable predictor of ptosis correction success.
Conclusions:
- The study did not establish a statistically significant correlation between IPDL and ptosis improvement (MRD1).
- Further research is required to definitively understand the relationship between these metrics.
- Current findings suggest IPDL is not a sole indicator for successful ptosis surgery outcomes.
Abstract:
Background: The objective of this study is to establish a potential correlation between postoperative improvement in upper eyelid ptosis, measured by the marginal reflex distance 1 (MRD1), and the immediate postoperative degrees of lagophthalmos (IPDL). The established correlation is then used to assess whether IPDL can be used as a reliable indicator of successful treatment of eyelid ptosis. Methods: This retrospective study involved 19 patients, aged 1 to 11, with a total of 28 eyes affected by ptosis, who underwent surgery under general anesthesia at Seoul National University Bundang Hospital from January 2018 to December 2022. We monitored the MRD1 of the patients for over six months postoperatively and measured the IPDL. Results: After ptosis correction surgery, no statistically significant correlation was observed between the improvement in MRD1 and IPDL. Furthermore, the degree of postoperative eyelid ptosis improvement was found to vary and was not consistently sustained, attributable to a range of factors. Conclusions: Our study did not establish a statistically significant correlation between IPDL and ptosis improvement as measured by MRD1. Further research is needed to draw definitive conclusions about their correlation.
