Observation of Gonio Structures during Microhook Ab Interno Trabeculotomy Using a Novel Digital Microscope with Integrated Intraoperative Optical Coherence Tomography

Figure 1

Intraoperative integrated optical coherence tomography (iOCT) during microhook ab interno trabeculotomy. (a) Intraoperative findings during microhook ab interno trabeculotomy. Under observation using a Swan-Jacob gonioprism lens, a microhook is inserted into Schlemm’s canal. In this left eye, the nasal angle is being incised with the straight microhook that is inserted from the temporal corneal port. (b) Intraoperative observation of the incised trabecular meshwork and inner wall of Schlemm’s canal by five-line scans using the ARTEVO 800 with iOCT in combination with a Swan-Jacob gonioprism lens. In this left eye, the nasal angle is visualized with iOCT. The green arrows indicate the scan direction.
