The Effect of Posterior Approach Ptosis Surgery vs. Anterior Approach Ptosis Surgery on Signs of Dry Eye Syndrome
Author: Ofira Zloto
ePoster Number: 162,00
Purpose
To examine the effect of combined blepharoplasty and Müller muscle-conjunctival resection (MMCR) compared to combined blepharoplasty and levator aponeurosis advancement (LAA) surgery on dry eye syndrome (DES).
Methods
This is a prospective comparative case series. Twenty-five adult MMCR patients with dermatochalasis and ptosis that showed significant improvement after phenylephrine 10% instillation, and 22 adult LAA patients with dermatochalasis and ptosis with good levator aponeurosis function without comparable improvement after the same treatment.
Results
The patients in both groups (MMCR, LAA) had significant improvement in MRD1 postoperatively (Delata MRD1- 2.65, 1.82, paired t test, P < 0.01 and P < 0.01, respectively). There were significant decraese in the postoperative TBUT, Schirmer test, and increase in fluorescein staining following MMCR surgery compared with the preoperative values (paired t test, P < 0.01, P = 0.01, and P <0.01, respectively), while the LAA patients had significant differences in their decrease in TBUT and increase in fluorescein staining, and LG results compared to their preoperative results (paired t test, P <0.01, P < 0.01, and P < 0.01). The postoperative vs. preoperative change in the Schirmer test results was significantly higher in the MMCR group compared to the LAA group (ANOVA, P < 0.01).
Conclusion
Both MMCR and LAA surgical approaches cause an increase in signs of DES. This increase is attributed to both aqueous tear deficiency and evaporative dry eye (EDE) has shown in different tests, following MMCR surgery, and due to EDE alone after LAA surgery. Physicians need to be aware of the risk of DES and discuss it as a potential complication with patients prior to ptosis surgery. LAA may be considered a preferable option compared to MMCR in cases of severe ptosis and DES.
