Abstract

Purpose: To evaluate the accuracy of anterior segment optical coherence tomography (as-oct) meniscometry, its efficacy as a marker of success in laser endonasal dacryocystorhinostomy and its correlation with the lacrimal duct permeability after surgery.

Methods: As-oct imaging was performed in 37 eyes of 37 subjects with severe tearing (munk grade 3 or more) and lacrimal duct obstruction, explored by irrigation, before and after laser endonasal dacryocystorhinostomy surgery. All images were taken using as 3d-OCT-1000 (Topcon, inc., Japan). Fastmap software was used to measure lower tear meniscus high (TMH), and lower tear meniscus depth (TMD).

Results: A Pearson correlation between TMH and TMD before and after surgery of R 0.860 and 0.716 respectively was found. Independent sample tests showed significant differences (p<0.05) in both,TMH and TMD images before and after surgery between patients with successful lacrimal duct permeability (n=24) and failure surgeries (n=13). Compared with the baseline THM and TDM measurements (742.7±193.8 and 537±97um respectively) there was an average decrease in 253um (TMH) and 198,7um (TMD) after surgery.

Conclusions: A significant correlation between the success of the surgery and the TDM and THM measurements after surgery was found. AS-OCT meniscometry has shown to be a reproducible and non invasive tool to evaluate the efficacy of the laser endonasal dacryocystorhinostomy surgery.
