Blepharoptosis surgery significantly decreased tear volume, measured by tear meniscus radius, especially in patients with initially higher tear volumes. This finding impacts post-surgical eye care strategies.
Area of Science:
- Ophthalmology
- Surgical Outcomes
Background:
- Blepharoptosis, or drooping eyelids, can affect vision and ocular surface health.
- Surgical correction aims to improve eyelid function and aesthetics.
Purpose of the Study:
- To evaluate changes in tear volume after blepharoptosis surgery using videomeniscometry.
- To assess the relationship between preoperative tear volume and postoperative changes.
Main Methods:
- Videomeniscometry was used to measure tear meniscus radius in 59 eyes of 36 patients before and 1.5 months after levator advancement surgery.
- Margin reflex distance-1 was also measured to confirm surgical success.
Main Results:
- Blepharoptosis surgery significantly increased margin reflex distance-1 (P < 0.001).
- A significant decrease in average tear meniscus radius was observed postoperatively (P < 0.001), indicating reduced tear volume.
- Postoperative tear volume reduction occurred in 78% of eyes, with higher preoperative tear volumes more likely to decrease.
Conclusions:
- Blepharoptosis surgery leads to a reduction in tear volume.
- The degree of tear volume reduction is more pronounced in patients with initially higher tear volumes.
