The Effect of Ptosis Surgery on Meibomian Glands and Dry Eye Syndrome

Abstract

Purpose: To investigate the effect of ptosis surgery on dry eye disease as measured by dry eye parameters and meibomian gland function.

Methods: This prospective, case series study included patients with involutional ptosis with no prior history of dry eye disease who were scheduled for a levator aponeurosis advancement procedure. Dry eye evaluation included the ocular surface disease index (OSDI) questionnaire as well as objective measurements, which included meibomian gland loss measured by meibography, meibomian gland disease grading, tear breakup time (TBUT), corneal and conjunctival fluorescein staining, tear meniscus height, and Schirmer testing. All dry eye measurements were recorded preoperatively and repeated 21-28 days postoperatively.

Results: A total of 30 eyes were included with a mean age of 65.6 ± 11.9 years. There was a significant improvement in margin reflex distance1 (MRD1) postoperatively ( p < 0.001) and a significant decrease in upper lid margin thickening ( p = 0.022). There were no significant differences between the pre- and postoperative measurements in meibomian gland loss, TBUT, corneal and conjunctival fluorescein staining, tear meniscus height, and the Schirmer test. OSDI was increased nonsignificantly postoperatively (16.094 vs. 24.296, respectively, p = 0.107).

Conclusion: The levator aponeurosis advancement procedure does not affect the eyelid meibomian glands, nor does it cause an increase in dry eye signs and symptoms, according to the measured parameters.
