Kyle A Den Beste, Constance Okeke
RATIONALE: Bilateral acute iris transillumination (BAIT) is a poorly-understood ocular syndrome in which patients present with acute iridocyclitis and pigmentary dispersion with or without ocular hypertension. The etiology of the disease remains unknown, though recent reports suggest an antecedent upper respiratory tract infection or systemic antibiotic administration may trigger the clinical syndrome. PATIENT CONCERNS: A 55-year-old female was referred for a second opinion regarding her bilateral ocular pain, photophobia, and ocular hypertension...

BACKGROUND: Trabectome surgery combined with phacoemulsification is effective in lowering (intraocular pressure) IOP in pseudoexfoliation glaucoma. Trabectome surgery usually aims to remove two to four clock hours of the trabecular meshwork. When adding trabecular aspiration, the remaining meshwork can be treated as well, and therefore 360 degrees of the meshwork can be reached. This study was conducted to investigate the additional benefits and risks of adding trabecular aspiration to the combination of phacoemulsification and trabectome as a triple procedure...

PURPOSE: Ab interno trabeculectomy (AIT) with the Trabectome has been shown to reduce intraocular pressure (IOP) in eyes with pseudoexfoliation (PEX) glaucoma. Here, we examined the change of IOP fluctuations before and after only AIT or AIT with cataract surgery in PEX patients using the contact lens sensor Triggerfish(®). METHODS: This was a prospective open-label study. Twenty-four consecutive patients with PEX glaucoma were included. Twelve patients underwent cataract surgery and AIT (triple-surgery group), and 12 patients underwent only AIT (single-surgery group)...

PURPOSE: To apply propensity score matching to compare Baerveldt glaucoma drainage implant (BGI) to Trabectome-mediated ab interno trabeculectomy (AIT). Recent data suggests that AIT can produce results similar to BGI which is traditionally reserved for more severe glaucoma. METHODS: BGI and AIT patients with at least 1 year of follow-up were included. The primary outcome measures were intraocular pressure (IOP), number of glaucoma medications, and a Glaucoma Index (GI) score...

BACKGROUND: The aim of this study was to investigate the factors that influence the outcome of trabectome surgery. METHODS: This was a retrospective nonrandomized study. Seventy-eight glaucoma patients (86 eyes) who underwent trabectome surgeries and were followed up for more than 12 months were included. We classified the subtypes of glaucoma as: primary open-angle glaucoma (23 eyes), pseudo-exfoliation glaucoma (58 eyes), and secondary glaucoma (5 eyes). Forty-seven eyes underwent cataract and trabectome surgeries simultaneously, and 39 underwent only trabectome surgery...

The purpose of this systematic review and meta-analysis was to examine the availability of evidence for one of the earliest available minimally invasive glaucoma surgery (MIGS) procedures, the Trabectome. Various databases were searched up to December 20, 2016, for any published studies assessing the use of the Trabectome as a solo procedure in patients with primary open-angle glaucoma (POAG). The standardized mean differences (SMD) were calculated for the change in intraocular pressure (IOP) and number of glaucoma mediations used at 1-month, 6-month, and 12-month follow-up...

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...

BACKGROUND: Trabeculotomy with the Trabectome® is an effective surgical procedure to lower intraocular pressure (IOP). However, in some patients it does not lead to a significant IOP reduction despite a gonioscopically well visible opening of Schlemm's canal. This study investigated whether the size of the trabeculotomy opening and other parameters, including anterior chamber depth (ACD) are related to IOP reduction. METHODS: Retrospective observational case series with 93 eyes of 93 patients who underwent Trabectome surgery...

Increasing prevalence and cost of glaucoma have increased the demand for surgeons well trained in newer, microincisional surgery. These procedures occur in a highly confined space, making them difficult to learn by observation or assistance alone as is currently done. We hypothesized that our ex vivo outflow model is sensitive enough to allow computing individual learning curves to quantify progress and refine techniques. Seven trainees performed nine trabectome-mediated ab interno trabeculectomies in pig eyes (n = 63)...

REVIEW

In primary open-angle glaucoma, the site of greatest resistance to aqueous outflow is thought to be the trabecular meshwork (TM) and inner wall of Schlemm's canal. Augmentation of the conventional (trabecular) outflow pathway can facilitate physiologic outflow and subsequently lower intraocular pressure. The most recent approach to enhancing the conventional outflow pathway is via an internal approach to the TM and Schlemm's canal. Ab interno Schlemm's canal surgery includes 4 novel surgical approaches: (1) removal of the TM and inner wall of Schlemm's canal by an internal approach (ab interno trabeculectomy), (2) implantation of a microstent to bypass the TM, (3) disruption of the TM and inner wall of Schlemm's canal via an internal approach (ab interno trabeculotomy), and (4) dilation of Schlemm's canal via an internal approach (ab interno canaloplasty)...

REVIEW
Nathan M Kerr, Jing Wang, Keith Barton
Recently, many new devices and procedures have been developed to lower intraocular pressure in a less invasive and purportedly safer manner than traditional glaucoma surgery. These new devices might encourage an earlier transition to surgery and reduce the long-term commitment to topical glaucoma medications with their associated compliance and intolerance issues. Although often seen as an adjunct to cataract surgery, a growing body of evidence suggests that primary minimally invasive glaucoma surgery may be a viable initial treatment option...
