Effect of laser suture lysis on filtration openings: a prospective three-dimensional anterior segment optical coherence tomography study.

ABSTRACT:

Purpose

To investigate the effects of laser suture lysis (LSL) on filtration openings after trabeculectomy.

Methods

Prospective study analyzing the changes in the location and width of filtration openings, fluid cavity height, total bleb height, bleb wall thickness, and bleb wall intensity before and after LSL using three-dimensional anterior segment optical coherence tomography (3D AS-OCT).

Results

Fourteen patients had clear scleral flap image analysis. As five patients underwent LSL twice and two patients underwent LSL thrice, 23 comparison studies were possible. After LSL the intraocular pressure (IOP) decreased (P = 0.0015) from 20.5 ± 5.3 to 14.9 ± 6.4 mm Hg, and the fluid cavity height increased significantly from 0.2 ± 0.2 mm to 0.3 ± 0.1 mm (P = 0.0094).
