Summary
Ptosis surgery can negatively impact tear film quantity and quality. Pre-operative tear film evaluation is recommended before further eye surgeries in patients who underwent ptosis repair.
Area of Science:
- Ophthalmology
- Oculoplastics
Background:
- Unilateral blepharoptosis affects eyelid position.
- Ptosis surgery aims to correct eyelid drooping.
- The impact of ptosis surgery on ocular surface health is not fully understood.
Purpose of the Study:
- To evaluate changes in tear film quantity and quality after unilateral ptosis surgery.
- To assess the correlation between subjective dry eye symptoms and objective tear film measurements post-surgery.
Main Methods:
- Interventional case series involving 83 patients undergoing ptosis surgery (levator resection or frontalis sling).
- Tear film evaluation included Schirmer test (with/without anesthesia) and tear break-up time (TBUT) pre-operatively and at 1, 3, and 6 months post-operatively.
- Subjective dry eye symptoms were also assessed pre- and post-surgery.
Main Results:
- Post-surgery, a decrease in tear quantity (Schirmer test) and quality (TBUT) was observed over time.
- Patients reporting dry eye symptoms post-surgery exhibited significantly shorter TBUT.
- Congenital ptosis was the most common indication for surgery.
Conclusions:
- Ptosis surgery can lead to a decline in tear film parameters.
- Pre-operative assessment of tear film condition is crucial before subsequent ocular surgeries in these patients.
- Ocular surface health should be considered in the management of patients undergoing ptosis correction.
