Glaucoma Intrascleral Tube Surgery

Ahmed Elbably, MSc, FRCS

Show Description +

[No narration] In this video, glaucoma intrascleral tube surgery (GITS) is performed to modify the implantation of a Preserflo MicroShunt (Santen/Glaukos) and Xen Gel Stent (AbbVie). With this technique, a subconjunctival stent is embedded within a scleral lake (SL) beneath a partial-thickness scleral flap. This intrascleral passage alters aqueous flow dynamics and may shield the stent from fibrotic responses, thereby potentially improving surgical success and reducing postoperative complications.
