Research progress of gonioscopy-assisted transluminal trabeculotomy in the treatment of glaucoma

:478-488
 
房角镜辅助的内路360°小梁切开术(Gonioscopy-Assisted Transluminal Trabeculotomy,GATT)是近年来国内外开展的新型微创青光眼手术,是一种改良的小梁切开术。GATT将微导管(iTrack)环穿Schlemm's管后,利用微导管张力全周切开小梁网及Schlemm's管内壁,重建生理性房水流出通道,避免小梁网阻力,实现房水从前房直接进入集液管,通过增加房水流出机制降低眼压。GATT适应证广泛,主要应用于开角型青光眼,包括原发型开角型青光眼和继发性开角型青光眼,同时可运用于闭角型青光眼。GATT微创、不依赖滤过泡、能明显减少降眼压药物的使用、中远期疗效稳定、安全性高、较少发生威胁视力的并发症,可作为开角型青光眼的首选手术方式。本文将对GATT在青光眼中的应用、手术步骤、作用机制、有效性、并发症及影响疗效的因素等进行综述,以期为其临床运用提供参考。
As a modifed trabeculotomy, Gonioscopy-Assisted Transluminal Trabeculotomy (GAT) is a new type of minimally invasive glaucoma surgery developed at home and abroad in recent years. GAT inserts a microcatheter (iTrack) into the Schlemm's canal and advance the catheter through the canal circumferentially 360°, then circumferentially fracture the trabecular meshwork and inner wall of Schlemm’s canal. Tis method can reduce intraocular pressure by increasing the outfow of aqueous humor. Te physiological outfow pathway of aqueous humor is reconstructed, which can avoid the resistance of trabecular meshwork and realizing the direct entry of the aqueous humor directly into the collector channel from the anterior chamber. With a wide range of indications, GAT is mainly used in open-angle glaucoma, including primary open-angle glaucoma and secondary open-angle glaucoma, and is also used in primary closed- angle glaucoma. Additionally, GATT can be the preferred surgical modality for open-angle glaucoma, as it has the following advantages: minimally invasive, independent of fltration bleb, can signifcantly reduce the use of medications, stable medium- and long-term efcacy, high safety, and has fewer sight-threatening complications. In order to provide a reference for clinical application, this article reviews the indications, mechanism of action, surgical procedures, efectiveness, complication and factors afecting therapeutic efect.

:737-744
 
目的:观察超声乳化白内障吸除人工晶状体植入术(phacoemulsification with intraocular lens implantation, PEI)联合房角分离术(goniosynechialysis, GSL)及房角切开术(goniotomy, GT)治疗中晚期原发性慢性闭角型青光眼(chronic primary angle-closure glaucoma , CPACG)合并白内障的安全性和有效性。方法:采用回顾性病例研究。收集2020年6月至2024年1月在成都市中西医结合医院行PEI联合GSL及GT的中晚期CPACG合并白内障患者94例133眼,观察最佳矫正视力(best corrected visual acuity, BCVA)、眼压、抗青光眼药物使用数量及术后并发症等情况。采用重复测量方差分析、Wilcoxon秩检验进行统计学处理。结果:术后1天,1周,1、3、6个月94例患者133眼的BCVA(logMAR)均较术前有所提升(P<0.05);从术后1天到6个月的所有随访时间点眼压均较术前明显下降(F = 189.79,P<0.001);术后6个月,患者使用的降眼压药物数量明显低于术前 ( = -2.392,P<0.001)。术后1周中31眼(23%)出现角膜水肿,15眼(11%)出现前房积血,均在1周内消退;术后1个月内1眼出现眼压反跳,予以前房穿刺放液等治疗后眼压恢复到正常范围。术后6个月,121眼(91%)手术完全成功,10眼(8%)手术条件成功。结论:PEI联合GSL及GT治疗中晚期CPACG合并白内障可有效地提高视力、降低眼压,且无严重并发症。
Objective: To observe the safety and efficacy of phacoemulsification with intraocular lens implantation (PEI) combined with goniosynechialysis (GSL) and goniotomy (GT) in treating advanced chronic primary angle-closure glaucoma (CPACG) complicated by cataract. Methods: This was a retrospective case series study. We collected data from a total of 94 patients (133 eyes) who had advanced CPACG along with cataract and underwent PEI+GSL+GT at Chengdu Integrated TCM&Western Medicine Hospital between June 2020 and January 2024. We observed the best corrected visual acuity (BCVA), intraocular pressure (IOP), the number of anti-glaucoma drugs used, and postoperative complications. Repeated measures ANOVA and Wilcoxon rank test were used for statistical analysis. Results: The BCVA (logMAR) at 1 day, 1 week, 1, 3, and 6 months after surgery showed significant improvement compared to the pre-surgical values (F = 189.79,< 0.001); The IOP at 1 day, 1 week, 1, 3, and 6 months post-surgery was significantly lower than that pre-surgical IOP (P < 0.001). The number of IOP-lowering drugs used at 6 months after surgery was also significantly reduced compared to the pre-surgical (Z = -2.392, P < 0.001). One week after surgery, corneal edema occurred in 31 eyes (23%) and hyphema in 15 eyes (11%) , both of which resolved spontaneously within 1 week. Within one month after surgery, 1 eye experienced an IOP spike, and the intraocular pressure returned to normal range after treatments such as anterior chamber puncture and drainage. Six months after surgery, the operation was completely successful in 121 eyes (91%), and conditionally successful in 10 eyes (8%), resulting in an overall surgical success rate of 99%. Conclusions: PEI combined with GSL and GT can effectively improve vision and reduce IOP in patients with advanced CPACG complicated by cataract, without causing serious complications.

:653-664
 
目的:通过真实的临床病例,分析青光眼与非青光眼性视神经病变的不同表现,提高疾病的鉴别诊断能力。方法:采用病例研究与文献回顾方法,记录3例易误诊为正常眼压性青光眼(normal tension glaucoma, NTG)的神经眼科病例,通过视力、眼压、瞳孔对光反应、视盘形态、RNFL厚度、视野损害等特点,抽丝剥茧,得出诊断。结果:病例1视野呈弓形缺损,但视盘凹陷不深,且对侧眼“视盘拥挤”,随访期间发生急性前部缺血性视神经改变(anterior ischaemic optic neuropathy, AION),最终确诊“AION遗留视神经萎缩”。病例2视力下降、视野缺损与视神经结构损害不相符,经完善MRI确诊为“左侧视神经鞘膜瘤”。病例3青年男性,中心视力下降,视盘凹陷不深,根据DNA结果确诊Leber遗传性视神经病变(Leber hereditary optic neuropathy, LHON)。结论:通过几个典型的神经眼科病例,掌握AION、视神经鞘膜瘤、LHON的结构和功能损害特征,如视盘凹陷不深、中心视力下降、视神经结构损害与视功能不相符,与NTG相鉴别。
Objective: To analyze the differentiating manifestations of glaucomatous and non-glaucomatous optic neuropathies using real clinical cases and to enhance the ability to make differential diagnosis. Methods: By using case study and literature review methods, we recorded three neuro-ophthalmic cases that were prone to being misdiagnosed as normal tension glaucoma (NTG). The diagnosis was established by extracting features related to visual acuity, intraocular pressure, pupillary light reflex, optic disc morphology, retinal nerve fiber layer (RNFL) thickness and visual field damage. Results: Case 1 presented with arcuate visual field defects, shallow optic disc cupping, and contralateral crowded discs. During follow-up, the patient subsequently developed acute anterior ischemic optic neuropathy (AION), and the final diagnosis confirmed was confirmed as optic atrophy secondary to AION. Case 2 exhibited a disproportionate visual acuity decline and visual field defects that were inconsistent with glaucomatous structural damage. MRI confirmed the diagnosis of left optic nerve sheath meningioma. Case 3 involved a young male who presented with central vision loss and shallow optic disc cupping. Genetic testing confirmed Leber's hereditary optic neuropathy (LHON). Conclusions: Through these representative neuro-ophthalmology cases, we illustrate the characteristic patterns of structural and functional damage associated with  AION, optic nerve sheath meningioma, and LHON, such as shallow optic disc cupping, central vision loss, and inconsistency between  optic nerve structural damage and visual function. These findings highlight the key differentiating features of these conditions from NTG.

The safety and effi cacy of modifi ed minimally invasive trabeculectomy for the treatment of primary chronic angle-closure glaucoma

:160-166
 
Background: Primary chronic angle-closure glaucoma (PCACG) is one of the main types of glaucoma in China. Trabeculectomy is the most commonly used glaucoma filtration surgery for glaucoma in the world. Conventional trabeculectomy is prone to anesthesia-related complications intraoperative and operationrelated complications postoperative in PCACG treatment. Modified minimally invasive trabeculectomy maybe can reduce the incidence of complications.
Methods: We conducted a prospective case series study and performed modified fornix-based trabeculectomy in 27 patients (30 eyes) under topical anesthesia; we then observed intraoperative anesthesia and cooperation effect, intraoperative and postoperative complications, preoperative and postoperative visual acuity, intraocular pressure (IOP), visual field, and the use of ocular hypotensive drugs. The patients were followed up for at least 12 months.
Results: All operations were completed successfully with no intraoperative complications. All 27 patients (30 eyes) were followed up for at least 12 months. No significant decrease in visual acuity was observed at days 1 or 7 and at months 1, 3, 6, and 12 after operation; however, a significant decrease in IOP was observed at days 1 and 7 and at months 1, 3, 6, and 12 after operation. Moreover, no significant progression in visual field mean defect was observed at month 12 after operation, and the number of ocular hypotensive drugs required was significantly reduced at months 6 and 12 after operation. By month 12 after operation, the overall success rate was 93.33% (28/30).
Conclusions: Modified minimally invasive trabeculectomy is safe and effective for the treatment of PCACG.
