ABSTRACT Objective: To evaluate the real-world long-term effectiveness and safety of the standalone use or in combination with cataract surgery of the second-generation trabecular implant, iStent inject®. Methods: A retrospective longitudinal study was carried out on a series of cases that underwent iStent inject® trabecular implantation alone and associated with cataract surgery. In addition to sociodemographic data, the parameters evaluated included intraocular pressure, number of medications, visual acuity, and possible complications from surgical interventions throughout follow-up. The effectiveness of the […]

ABSTRACT Objective: To know the profile of trabeculectomy, in addition to the success rate in controlling intraocular pressure in patients with glaucoma. Methods: A retrospective, observational study, with medical records of patients with glaucoma, followed up at an ophthalmological reference center, who underwent trabeculectomy from January 1, 2016 to May 31, 2017, by a single experienced surgeon. The success rate was considered with an intraocular pressure < 21 mmHg, for high intraocular pressure glaucoma, and a reduction of at least [...]

ABSTRACT The rate of visual field progression is an essential factor in determining risk of visual disability or blindness in glaucoma patients. Knowledge of the rate of progression of a particular patient, in combination with an estimation of their longevity and other clinical factors, allows clinicians to optimize management by providing appropriately aggressive treatment. Despite decades of research on the treatment of glaucoma, the natural history of glaucomatous visual field progression in untreated and treated patients remains unclear. The purpose […]

ABSTRACT Glaucoma drainage devices are important therapeutic options for cases of refractory glaucoma, in which trabeculectomy with antimetabolites has shown high risk of failure. There are devices with different sizes, designs and materials, and several studies have been conducted to test their safety and effectiveness. Despite known complications, their use has progressively increased in recent years, and they are the primary surgical option, in some situations. The aim of this review is to discuss the importance, mechanisms, biomaterials, results and […]

ABSTRACT The purpose of this study was to highlight the impact of biomechanical corneal response in available in vivo tonometry methods for glaucoma management. Systematic review of non-contact air-puff tonometers that analyzes the corneal deformation response, with special focus on the investigation of the correlation of derived parameters with intraocular pressure measurements. The two actual and commercially available in vivo corneal tonometers provide promising information about biomechanical characteristics of the cornea and its relation to glaucoma, allowing the development of […]

ABSTRACT Objective To evaluate efficacy of gonioscopy-assisted transluminal trabeculotomy and relate to severity of glaucoma. Methods A retrospective analysis of medical records of patients submitted to gonioscopy-assisted transluminal trabeculotomy, at a private hospital, from 2019 to 2021. Results A total of 20 were submitted to gonioscopy-assisted transluminal trabeculotomy (2 eyes) or facectomy and gonioscopy-assisted transluminal trabeculotomy (18 eyes). Patients with advanced-stage disease achieved a decrease by 5 mmHg (26.5%) in IOP, with a reduction of 2.3 drugs, and eyes with […]

ABSTRACT Acute ocular hypertension during hemodialysis is a rare event and may lead to interruption of dialytic therapy due to pain. A case of a 70-year-old male patient is reported, who presented recurrent intense unilateral ocular pain episodes during dialysis sessions for increased intraocular pressure. The patient presented with severely decreased visual acuity in the right eye due to neovascular glaucoma, which was controlled with topical hypotensive medication. One hour after initiating dialysis, he presented an excruciating pain on the […]

Abstract We describe the case of a patient with secondary glaucoma who developed tenon cyst after Ahmed valve implantation. Despite the initial expectant management and subsequent surgical interventions, only with the micropulse transecleral cyclophotocoagulation did the intraocular pressure reach acceptable values.
