Long-Term Structural Changes Observed on Gonioscopy and Anterior-Segment OCT Following Gonioscopy-Assisted Transluminal Trabeculotomy.

AS-OCT, when used in conjunction with gonioscopy, was found helpful to evaluate the structural changes following GATT. As observed in the study, the cleft tended to close in some areas. It was found preserved mostly in the superior half of the angle in the long term.
