Purpose. Provide data on the use of gonioscopy-assisted transluminal trabeculotomy (GATT), reflecting its effectiveness and safety when using this technique in various patient models. Material and methods. To perform the review, literature sources which were searched through the PubMed and Scopus databases up to and including 2021, using the keywords "gonioassociated trabeculotomy", "minimally invasive glaucoma surgery", "primary open-angle glaucoma", "glaucoma", "secondary glaucoma". A total of 19 articles related to the topic of the review were selected. The beginning of publications on this topic dates back to 2013. Results. GATT can be used at various stages of glaucoma, but at the same time, the maximum effect of lowering intraocular pressure (IOP) is achieved in patients with an early or middle stage of glaucoma. There are also good results of using the GATT technique after vitreoretinal surgery, with the development of secondary glaucoma or ophthalmic hypertension. One of the advantages of GATT is that all manipulations are performed in the anterior chamber, which in turn makes it possible, if necessary, to perform reoperation after an unsuccessful ad-externo trabeculotomy without re-traumatizing the sclera and conjunctiva. It should be noted that the main complication in all studies is the hyphema, which is completely absorbed within a few days. Conclusion. Based on these studies, it can be concluded that the proposed GATT technique is relevant, and meets all modern standards of minimally invasive glaucoma surgery (MIGS): micro-incision, minimal trauma, is able to effectively reduce IOP, has a high level of safety and quick recovery.

Abstract Purpose The aim of this study is to evaluate the long-term efficacy of a novel minimally invasive glaucoma surgery technique (MIGS), Ab interno Canaloplasty (AbiC). Material and Methods For this retrospective cohort study, we analysed the data of 25 eyes of 23 patients with open angle glaucoma who underwent an AbiC (6 eyes) or in case of an additional cataract, a combined cataract-AbiC procedure (“phacocanaloplasty ab interno”, 19 eyes), respectively. Postoperatively, we investigated the intraocular pressure (IOP) and the number of still required IOP-lowering medication, as well as surgery-related complications. Results Overall, the mean baseline IOP of 20.24 mmHg ± 5.92 (n = 25) was reduced to 10.64 mmHg ± 2.77 (n = 25, p < 0.001), 12.55 mmHg ± 3.33 (n = 22, p < 0.001) and 13.67 mmHg ± 2.15 (n = 21, p < 0.001) at 1 day, 1 year and 2 year follow-up visit, respectively. Compared to baseline, this implies a reduction in IOP of 47.4, 37.9 and 32.5%. An average glaucoma medication usage of 1.92 ± 1.04 was registered at baseline visit and was reduced to 0,05 ± 0,23 after 2 years of follow-up. 80% of patients were off medication. In 5 eyes (20%) further antiglaucomatous eye drops or surgical treatment were administered. The only surgical complications were hyphema in 5 eyes (20%) and a localized peripheral detachment of the Descemetʼs membrane in one eye (4%) with no late sequelae. Conclusion AbiC performed independently or combined with cataract surgery seems to be a safe and effective MIGS-technique with good long-term regulation of IOP and low risk profile.

Abstract Background: Glaucoma surgery have been developed to lower intraocular pressure in a less invasive manner than traditional glaucoma surgery. The purpose of this article is to determine the outcome of using combined phacoemulsification technique, ab-interno trabeculectomy dual blade and endoscopic cyclophotocoagulation (ECP) surgeries in patients with primary open angle glaucoma. Methods: A retrospective case series was performed on 27 consecutive eyes with both primary open-angle glaucoma (POAG) and cataract; each eye was treated with combined phacoemulsification, ab-interno trabeculectomy-Kahook Dual Blade and Endocyclophotocoagulation at Instituto de ojos Oftalmosalud, Lima, Peru, between April 2017 and May 2017. Inclusion criteria: 1) Patients with uncontrolled mild to advanced POAG (according to Glaucoma Grading Scale HODAPP) 2) cataract condition 3) treatment with two or more glaucoma medications due to rapid progression in the visual fields (at least two in a short period of time). Intraocular pressure (IOP), best corrected visual acuity (BCVA) logMAR and number of glaucoma medications were recorded prior to the study, at day 1, week 1, and 1,3,6 and 9 months after surgery. Primary outcome measure was surgical success defined in terms of IOP <14 mmHg either with no medications (complete success) or with medications (qualified success). Results: A total of 27 eyes from 27 patients were included. The mean basal IOP was 17.0±3.7 mmHg and postoperatively was 11.6±1.9 mmHg and 11.4±1.8 mmHg (P<0.001) at 6 and 9 months respectively. Glaucoma medications decreased from 1.9±1.4 to 0.56±1.05 at 9 month follow-ups (P<0.001). Preoperative best corrected visual acuity (BCVA) showed and improvement from 0.4± 0.4 LogMAR to 0.2 ± 0.4 logMAR at 9 months. The main complication was blood reflux intra-operatively (66.7%), which resolved without re-operation. The mean IOP was reduced by 32.9% from baseline and the surgical success was 92,6%, (complete success 70,3% and qualified success 29,6%) at 9 months.Conclusions: In patients with POAG, combined treatment with phacoemulsification, ab-interno trabeculectomy and endoscopic cyclophotocoagulation effectively reduced IOP and glaucoma medication dependence.

Purpose. To assess the safety and efficacy of Trabectome procedure in patients with preoperative intraocular pressure (IOP) of 30 mmHg or higher. Methods. All patients who had underwent Trabectome stand-alone or Trabectome combined with phacoemulsification were included. Survival analysis was performed by using Kaplan-Meier, and success was defined as IOP ≤ 21 mmHg, 20% or more IOP reduction from baseline for any two consecutive visits after 3 months, and no secondary glaucoma surgery. Results. A total of 49 cases were included with an average age of 66 (range: 13–91). 28 cases had Trabectome stand-alone and 21 cases had Trabectome combined with phacoemulsification. Mean IOP was reduced from a baseline of 35.6 ± 6.3 mmHg to 16.8 ± 3.8 mmHg at 12 months (p<0.01∗), while the number of medications was reduced from 3.1 ± 1.3 to 1.8 ± 1.4 (p<0.01∗). Survival rate at 12 months was 80%. 9 cases required secondary glaucoma surgery, and 1 case was reported with hypotony at day one, but resolved within one week. Conclusion. Trabectome seems to be safe and effective in patients with preoperative IOP of 30 mmHg or greater. Even in this cohort with high preoperative IOP, the end result is a mean IOP in the physiologic range.
