Longitudinal bleb morphology in anterior segment <scp>OCT</scp> after minimally invasive transscleral ab interno Glaucoma Gel Microstent implantation

Abstract

Bleb appearance after XEN surgery seems to be different to classic trabeculectomy literature. The present data suggest correlation of IOP and surgical long-term success with bleb morphology in AS-OCT. Prevalence of small diffuse cysts is directly associated with lower IOPs, while cystic encapsulation at 3 months predicts higher surgical failure.
