Summary
Müller muscle-conjunctival resection for ptosis repair did not significantly alter tear production. While some patients experienced temporary dry eye symptoms post-surgery, these often resolved, with no long-term impact on tear quantity.
Area of Science:
- Ophthalmology
- Oculoplastics
Background:
- Upper eyelid ptosis can affect vision and aesthetics.
- Müller muscle-conjunctival resection is a surgical technique for ptosis repair.
- The impact of this surgery on tear production requires investigation.
Purpose of the Study:
- To evaluate the effect of Müller muscle-conjunctival resection on tear production.
- To assess changes in dry eye symptoms following ptosis repair.
Main Methods:
- Retrospective chart review of 38 patients (71 surgeries) who underwent Müller muscle-conjunctival resection.
- Schirmer testing performed preoperatively and postoperatively (6 weeks to 18 months).
- Patient-reported dry eye symptoms assessed pre- and post-surgery.
Main Results:
- No statistically significant change in tear production measured by Schirmer testing.
- Preoperative dry eyes were present in 34% of eyes, with no change at long-term follow-up.
- Transient increase in dry eye symptoms occurred in 29% of patients immediately post-surgery, with 16% experiencing persistent symptoms at long-term follow-up.
Conclusions:
- Müller muscle-conjunctival resection for ptosis repair does not significantly affect tear production.
- Postoperative dry eye symptoms are often transient and tend to resolve.
- The surgical procedure appears safe concerning tear film integrity.
