“…This flexibility is its most significant advantage. Yokoyama et al 28 compared trabeculotomy with TMH to GATT in a retrospective study, including 169 eyes (GATT 122 and TMH 47) and found that mean IOP at 12 months was generally similar between the groups (mid-teens) but with a slightly lower success rate for TMH (71% vs 62%; success defined as IOP between 5 mm Hg and 18 mm Hg and a ≥20% IOP reduction with no additional glaucoma surgery).…”

The development of minimally invasive glaucoma surgeries (MIGSs) was intended to provide safe and modestly efficacious modalities for early intervention of mild-to-moderate glaucoma, with minimal trauma and rapid recovery. They were mainly ab interno procedures that reduce intraocular pressure by facilitating the aqueous outflow by bypassing the trabecular meshwork resistance, reinforcing the uveoscleral flow via the supraciliary space, and reducing aqueous production by the ciliary body. While the cumulating evidence helps shape the role of the available MIGS, the exponential new development and advancement in this field has expanded the territory of MIGS. Apart from developing subconjunctival MIGS filtration devices (Xen gel stent and PRESERFLO MicroShunt), there is a tendency to revisit the “traditional” MIGS for alternative use and to modify the procedures with consideration of the fundamental aqueous outflow physiology. Combined MIGS has also been suggested, based on the theory that their different mechanisms may provide additive or synergistic effects. The advancement of laser procedures is also promising and could supplement unmet needs along the glaucoma treatment algorithm. This review examines the broad array of MIGS, updates the recent findings, discusses their potential alternative applications, and explores future challenges.

“…Mori et al, 13 Sato and Kawaji, 15 Hirabayashi et al, 16 Okada et al, 18 reported that there was no difference in the surgical effectiveness in the treatment of open angle glaucoma with regard to success rate, final IOP, or IOP reduction; these studies compared 180 degrees versus 360 degrees, one-quadrant versus two-quadrant, 120 degrees versus 180 degrees, and 120 degrees versus 360 degrees, respectively. In contrast, Yokoyama et al 17 found that 360 degrees suture trabeculotomy outperformed the sectoral microhook trabeculotomy. Qiao et al 14 reported that the reduction of IOP was greater in GATT than in KDB trabeculotomy.…”

“…360-degree gonioscopy-assisted transluminal trabeculotomy (GATT) is used with the assistance of an iTrack system (iScience Interventional) 12 . Each of these procedures can lower IOP in POAG 13–18 . Published studies showed that there was a discrepancy in a different range of GT on the IOP-lowering effect and its safety.…”

Précis: Goniotomy (GT) 120 degrees with or without phacoemulsification was sufficient to lower the intraocular pressure (IOP) and reduce hyphema for primary open angle glaucoma. Purpose: To compare the surgical outcomes and safety profiles of 120 degrees and 360 degrees GT with or without phacoemulsification cataract extraction and intraocular lens implantation (PEI) for primary open angle glaucoma. Patients and Methods: This multicenter retrospective study consisted of 139 eyes and was divided into 4 groups: (1) 120 degrees GT, (2) 360 degrees GT, (3) PEI + 120 degrees GT, and (4) PEI + 360 degrees GT. IOP, number of topical hypotensive medications, and complications were recorded and evaluated at baseline and at the final visit. The complete and qualified success rate and their potential associated factors were also investigated. The effectiveness and safety profile of the surgery were compared between different subgroups. Results: After a mean follow-up of 8.6 months, the IOP reduction was 13.2 ± 8.3 (38.8 ± 28.8%), 12.4 ± 8.3 (41.6 ± 18.2%), 12.8 ± 9.9 (39.4 ± 34.5%), and 13.8 ± 7.2 (46.0±17.1%) mm Hg in 120 degrees, 360 degrees, PEI + 120 degrees GT group, and PEI + 360 degrees GT, respectively. No significant difference was found in IOP, a decline of IOP from baseline, topical hypotensive medication, and complete or qualified success between either standalone 120 degrees versus 360 degrees GT, or PEI + 120 degrees versus PEI + 360 degrees GT (all Ps > 0.05). The PEI + 120 degrees GT group had a lower final IOP than the 120 degrees GT group (P = 0.0002) whereas there was no difference between PEI + 360 degrees GT and 360 degrees GT group (P = 0.893). Both 360 degrees GT and PEI + 360 degrees GT group had a significantly higher incidence of hyphema than the 120 degrees GT and PEI + 120 degrees GT groups (all Ps < 0.0001). Conclusions: GT of 120 or 360 degrees lowered IOP equally with or without cataract surgery, and hyphema was most commonly noted after complete GT. Partial GT alone or in combination with cataract surgery was an effective and safe approach to manage patients with open angle glaucoma.

“…Studies on cadaver eyes suggested that the extent of trabeculotomy incision influences IOP reduction [4]. While some studies reported varying IOP reduction efficacy based on the width of the surgical extent [5][6][7], others found no such differences [8][9][10][11][12][13]. Assessments of the correlation between surgical extent and IOP reduction efficacy often involved comparing different surgical procedures or groups with varying preoperative IOP or patient backgrounds [5][6][7]10,13].…”

This study compared the effectiveness and safety of 120-degree (nasal) and 240-degree (bilateral) incisions in Tanito Microhook Trabeculotomy (TMH) combined with cataract surgery in patients with open-angle glaucoma. From a pool of 185 eyes, 67 eyes from 67 subjects were selected for each incision group using propensity score matching to align age, sex, glaucoma type, and preoperative intraocular pressure (IOP). The study found that preoperative IOP, initially 18.6 mmHg in both groups, decreased to 13.2 mmHg in the nasal group and 12.8 mmHg in the bilateral group 12 months postoperatively, representing reductions of 29% and 31%, respectively. Similarly, medication scores decreased from 3.4 to 2.7 in the nasal group and from 3.1 to 2.5 in the bilateral group. Notably, the bilateral incision group exhibited a significantly higher hyphema red blood cell score compared to the nasal group (p < 0.0001). Across the study period, other parameters such as IOP, medication score, visual acuity, anterior chamber flare, corneal endothelial cell density, visual field mean deviation, and the frequency of surgical complications other than hyphema were similar between the groups. The study concluded that TMH combined with cataract surgery is equally effective and safe regardless of incision width, although narrower incisions resulted in reduced early postoperative hyphema.
