PurposeTo report long-term outcomes of deep sclerectomy (DS) in eyes with raised intraocular pressure (IOP) and glaucoma secondary to uveitis.Patients and methodsRetrospective consecutive case series of 43 eyes of 43 patients with uveitic glaucoma. Mitomycin C (MMC) 0.2-0.4 mg/ml was applied sub-conjunctivally prior to scleral flap dissection for 2-3 min in 35 eyes (81%). Combined phacoemulsification and DS was done in 4 cases (9%).ResultsMean follow-up was 68.5±33.5 months. In total, 23 eyes (53.5%) had previous intraocular surgery...

BACKGROUND: Residency training is the basis of good clinical and surgical practice. PURPOSE: The aim is to know the demographics, training experience, and perception of young ophthalmologists to improve the present residency programs in India. SETTING: Young ophthalmologists trained in India. METHODS: A survey was conducted by the Academic and Research Committee of the All India Ophthalmology Society, in 2014-2016 of young ophthalmologists (those trained between 2002 and 2012, with 2-10 years' postresidency experience) to gauge teaching of clinical and surgical skills during the postgraduate residency program...

RATIONALE: Neovascular glaucoma (NVG) is one of the most refractory types of glaucoma caused by high ischemic retinal disorders, resulting in severe visual loss. Intravitreal injections of ranibizumab have been reported to have anatomical and functional success in treating NVG. PATIENT CONCERNS-DIAGNOSES-INTERVENTIONS: We report a case with neovascular glaucoma due to central retinal vein occlusion who received combination therapy with intravitreal ranibizumab (IVR) injection, panretinal photocoagulation (PRP) and subsequent 5-fluorouracil (5-FU) augmented trabeculectomy...

PURPOSE: To investigate the safety and synergistic effect of topical bevacizumab after trabeculectomy surgery with mitomycin C (MMC). METHODS: In this prospective, non-randomized, comparative interventional study, 40 eyes from 40 patients with uncontrolled open-angle glaucoma were studied after they underwent primary trabeculectomy with mitomycin C (0.02% for 2 min). Following the procedure topical bevacizumab (4 mg/mL) was used for 2 weeks 4 times daily in group A...

PURPOSE: To compare releasable and regular sutures in combined angle and filtering surgery for primary congenital glaucoma. METHODS: A prospective study was conducted on 39 eyes (26 right eyes) of 39 children (20 boys; 19 girls) who had primary congenital glaucoma treated with combined trabeculotomy-trabeculectomy with mitomycin C and scleral flap closure with regular or releasable sutures. Follow-up was 24 months. Success rates (defined as an intraocular pressure [IOP] < 16 mm Hg without hypotony-related complications and/or lack of IOP-related progression of the disease) were studied and complications were noted...

During the last few years, there has been a considerable capacity of innovations in glaucoma surgery owing to new micro-stents increasing the aqueous outflow via transscleral routes, via the trabecular meshwork or the suprachoroidal space. These interventions can be easily performed in combination with small-incision cataract surgery. Even the well-known filtering procedures, trabeculectomy and drainage device surgery, formerly perceived as being outdated, re-achieve better reputation owing to refinements in surgical technique and improved surgical experience...

Purpose: This study evaluated specific relationships between pathogenic mechanisms and genetic polymorphisms in primary open-angle glaucoma (POAG). We analyzed the morphologies of trabeculectomy specimens obtained from patients with familial POAG. Methods: We used light microscopy and transmission electron microscopy to examine specimens obtained from 17 eyes of 14 patients with familial POAG. We also conducted exome analyses of two families and used targeted Sanger sequencing to analyze samples obtained from the remaining patients...

PURPOSE: To investigate the impact of surgical or medical reduction of intraocular pressure (IOP) on progressive normal-tension glaucoma followed up over 15 years. METHODS: Sixty eyes of 60 patients were divided into 3 intervention groups: group 1 (trabeculectomy, n = 17); group 2 (IOP reduction rate ≥15% with prostaglandin analogs, n = 24); and group 3 (IOP reduction rate <15% with prostaglandin analogs, n = 19).

AIM: To describe a novel technique of creating a landing strip within the trabecular meshwork to guide trabecular micro-bypass stent (iStent) implantation in patients who underwent phacoemulsification. METHODS: Thirty-four eyes from 30 patients who underwent iStent implantation after phacoemulsification from May 2014 to February 2015 were included in our retrospective study. All iStents were implanted via the "landing strip" technique. A 25-gauge microvitreoretinal blade was used to bisect the trabecular meshwork to less than 1 clock-hour, effectively creating a landing strip...

PURPOSE: To compare two surgical approaches for treating encapsulated blebs after trabeculectomy with mitomycin C, in terms of the development of intraocular pressure and progression of glaucoma in a long-term follow up: 1. bleb needling alone vs. 2. a combined approach of needling with additional transconjunctival scleral flap sutures, to prevent early ocular hypotony. METHODS: Forty-six patients with failing blebs after trabeculectomy with mitomycin C were enrolled in this study...

REVIEW
Bing Zhang, Jie Kang, Xiaoming Chen
Purpose. This system review studied the efficiency and safety of canaloplasty (CP) and compared the outcomes between CP and trabeculectomy (TE). Methods. Literatures were searched in PubMed and EMBASE. The meta-analysis was conducted on the postoperative outcomes in CP and then on the differences of outcomes between CP and TE. Results. In the meta-analysis, IOP decreased by 9.94 (95% CI 8.42 to 11.45) mmHg with an average AGM reduction of 2.11 (95% CI 1.80 to 2.42) one year after CP. The IOP reduction was significantly higher after TE than after CP, with an average difference of 3...

PURPOSE: The Water-Drinking Test (WDT) has been shown to predict the diurnal IOP change. This study evaluates the factors that may affect the WDT results. METHODS: This study was conducted on 203 glaucoma patients who had undergone trabeculectomy (53) or tube surgery (31), or had a medically controlled open-angle (82) or closed-angle (37) glaucoma. IOP was measured at baseline and then every 15 minutes over a one-hour period after drinking water. The main outcome measures were IOP change (increase in IOP from baseline) at all measurement time points, IOP peak (highest IOP after drinking water), IOP fluctuation (difference between IOP peak and baseline), and assessing the association of these IOPs with a patient's demographic and management modalities...

BACKGROUND: Human Tenon's fibroblasts (HTFs) play a crucial role in wound healing. They cause postoperative scarring of the filtering bleb and are thus responsible for trabeculectomy failure. This study aimed to find an effective and fast protocol for HTF isolation from trabeculectomy biopsies. The protocol was compared with the commonly recommended HTF isolation procedure, which uses Dulbecco's modified Eagle's medium (DMEM). We used Eagle's minimum essential medium (EMEM) enriched with fibroblast growth factor (FGF), which selectively promoted the proliferation of HTF cells...

Plasma-mediated ab interno trabeculectomy with the trabectome was first approved by the US Food and Drug Administration in 2004 for use in adult and pediatric glaucomas. Since then, increased clinical experience and updated outcome data have led to its expanded use, including a range of glaucomas and angle presentations, previously deemed to be relatively contraindicated. The main benefits are a high degree of safety, ease, and speed compared to traditional filtering surgery and tube shunts. The increasing burden of glaucoma and expanding life expectancy has resulted in demand for well-trained surgeons...
