“…Third, although AS-OCTA images were successfully acquired, they still had significant noise. Multiple image averaging is known to be helpful in improving image quality in posterior-segment OCTA 27 and AS-OCT, 43, 44 as well as posterior-segment OCT 45 . AS-OCTA imaging with multiple image averaging might be a possible method to improve the image quality in future studies.…”

“…I morphologically classified the appearance of the trabeculotomy cleft into three groups ( Figure 2 ), and the cleft at the anterior edge of the trabecular meshwork was the most frequent pattern after the incision using a microhook; this should associate with the significant IOP reduction after μ LOT [ 5 , 6 ], although the association between the patterns and surgical efficacy has not been clarified yet. Recently, based on postoperative observation using anterior segment OCT, a possible connection between the anterior chamber and suprachoroidal space through the iris root was reported in cases after trabectome surgery [ 8 ]. Although I did not find evidence of cyclodialysis or dissociation of the pectinate ligaments of the iridocorneal angle in our cases, iOCT can be used to elucidate the mechanism of the phenomenon reported by Akagi et al…”

Introduction Intraoperative observation of ocular structures using microscope-integrated optical coherence tomography (iOCT) has been adopted recently. I report my initial feasibility assessment of iOCT for the incised trabecular meshwork observation during microhook ab interno trabeculotomy. Case Series Both the nasal and temporal sides or either side of the trabecular meshwork/inner wall of Schlemm's canal was incised more than 3 clock hours. After then, under observation using a Swan-Jacob gonioprism lens with the real-time 5-line scan mode, OCT images of the area were successfully acquired in 10 (83%) of 12 sides in nine eyes. Based on the appearance of the acquired images of the 10 sides, the trabeculotomy cleft could be classified into three incisional patterns, that is, six (60%) anterior-opening patterns (posterior-based flap), three (30%) middle-opening patterns (posterior- and anterior-based flaps), and one (10%) posterior-opening pattern (anterior-based flap), according to the predominant locations of the trabecular meshwork flaps. Conclusion Intraoperative observation of the gonio structures including the trabeculotomy cleft was feasible using the RESCAN 700 in combination with a gonioprism.

“…Eyes with ciliochoroidal detachment had lower mean IOP than eyes that did not, but IOP was never <5 mmHg in any eyes. Only four eyes had persistent ciliochoroidal detachment at 1 month, but visual acuity was not reported 32. Osman and AlMobarak described a case of cyclodialysis cleft following AIT with hypotony (IOP <5 mmHg), persisting to the fourth postoperative month at the time of the report 33.…”

Ab interno trabeculectomy is one among several recently introduced minimally invasive glaucoma surgeries that avoid a conjunctival incision and full-thickness sclerostomy involved in traditional glaucoma surgery. Ablation of the trabecular meshwork and inner wall of Schlemm’s canal is performed in an arcuate fashion via a clear corneal incision, alone or in combination with phacoemulsification cataract surgery. Intraocular pressure reduction following ab interno trabeculectomy is limited by resistance in distal outflow pathways and generally stabilizes in the mid-to-high teens. Relief of medication burden has been demonstrated by some studies. A very low rate of complications, most commonly transient hyphema and intraocular pressure elevations in the immediate postoperative period, have been reported. However, available data are derived from small retrospective and prospective case series. Randomized, controlled trials are needed to better elucidate the potential merits of ab interno trabeculectomy in the combined setting versus phacoemulsification cataract surgery alone and to compare it with other minimally invasive glaucoma surgeries.
