Interventional Glaucoma: Improving the Patient-Provider Educational Exchange.

Glaucoma treatment is beginning to undergo an evolution, moving away from topical medication-based therapies toward more proactive minimally invasive interventions. This shift towards an "interventional glaucoma" treatment paradigm has been shown to benefit patients, providers, and society. A key component of effectively implementing this approach is education about the importance of glaucoma diagnosis and treatment, as well as the various treatment modalities available.

Long-Term Safety and Efficacy Evaluation of Travoprost Intracameral Implant Based on Pooled Analyses from Two Phase III Trials.

Aim: The purpose of this study was to conduct and interpret a pooled 12-month analysis of two prospective, multi-center, randomized, double-masked, controlled trials designed to assess the efficacy and safety of the travoprost intracameral implant (slow-eluting [SE] implant in development as a new therapeutic and fast-eluting [FE] implant included for masking purposes) in subjects with open-angle glaucoma (OAG) or ocular hypertension (OHT).

Methods: Subjects with OAG or OHT, on 0-3 intraocular pressure (IOP)-lowering medications, baseline unmedicated mean diurnal IOP of ≥ 21 mmHg, and IOP ≤ 36 mmHg at each baseline diurnal timepoint, received either a travoprost implant and twice-daily (BID) placebo eye drops or BID timolol 0.5% eye drops and a sham procedure.

Travoprost Intracameral Implant Demonstrates Superior IOP Lowering Versus Topical Prostaglandin Analog Monotherapy in Patients with Open-Angle Glaucoma or Ocular Hypertension.

Introduction: This study was conducted to analyze and compare the intraocular pressure (IOP) treatment effect of the slow-eluting (SE) travoprost intracameral implant to the IOP treatment effect of topical prostaglandin analog (PGA) monotherapy in a subgroup of subjects who were on pre-study PGA monotherapy prior to enrollment in the two pivotal phase 3 trials of the travoprost intracameral implant.

Methods: A combined study population of 133 subjects from two phase 3 trials, who were on topical PGA monotherapy at screening, subsequently underwent a washout period from their topical PGA, and then were randomized and administered an SE travoprost intracameral implant. The subjects were analyzed for the IOP treatment effects of the pre-study topical PGA monotherapy and the in-study SE travoprost intracameral implant.

Contemporary Approach to Narrow Angles.

Glaucoma is the leading cause of irreversible blindness worldwide. Among all glaucoma types, primary angle closure glaucoma (PACG) affects approximately 23 million people worldwide, and is responsible for 50% of glaucoma-related blindness, highlighting the devastating consequences of this disease. The main mechanism of PACG is relative pupillary block.

A Proposal for the Use of a Fixed Low-Energy Selective Laser Trabeculoplasty for Open Angle Glaucoma.

Selective laser trabeculoplasty (SLT) has been in routine clinical use for over 20 years with millions of patients successfully treated and a low rate of clinically significant complications. The procedure requires the clinician to manually position the laser beam on the trabecular meshwork using a gonioscopy lens and to titrate the SLT laser energy based on the amount of pigmentation in the angle, as well as the observation of small bubbles produced by the laser effect. We propose that SLT energy titration is unnecessary either to achieve intraocular pressure (IOP) reduction or to minimize potential side effects.

Changing from preserved, to preservative-free cyclosporine 0.1% enhanced triple glaucoma therapy: impact on ocular surface disease-a randomized controlled trial.

A review of potential novel glaucoma therapeutic options independent of intraocular pressure.

Glaucoma, a progressive optic neuropathy characterized by retinal ganglion cell degeneration and visual field loss, is the leading cause of irreversible blindness worldwide. Intraocular pressure (IOP) is presently the only modifiable risk factor demonstrated to slow or halt disease progression; however, glaucomatous damage persists in almost 50% of patients despite significant IOP reduction. Many studies have investigated the non-IOP-related risk factors that contribute to glaucoma progression as well as interventions that can prevent or delay glaucomatous neurodegeneration and preserve vision throughout life, independently of IOP.

Sociodemographic and Economic Factors in Outcomes of Tube Shunts for Neovascular Glaucoma.

Design: Randomized controlled trial analysis of secondary outcomes.

Methods: The Vision Function Questionnaire (VFQ-25) and Ocular Surface Disease Index (OSDI) questionnaire were administered at baseline and at months 1, 6, 12, and 24.

Improvement in structure and visual function in patients with glaucoma: the possible key to better treatment?

Glaucoma is characterized by retinal ganglion cell loss that can lead to permanent visual loss. Current clinical management practice assumes that glaucomatous visual loss is irreversible; however, there is increasing evidence that permanent vision loss and cell death are preceded by reversible functional and structural changes. We propose that these changes should be considered by glaucoma specialists when treating their patients.
