A Randomized Controlled Trial Comparing STREAMLINE Canaloplasty to Trabecular Micro-Bypass Stent Implantation in Primary Open-Angle Glaucoma.

Purpose: To report interim results of the VENICE study, a multi-center, randomized, controlled trial (RCT) comparing STREAMLINE Surgical System (STREAMLINE) canaloplasty with iStent inject W (iStent W) implantation in patients with mild-to-moderate primary open-angle glaucoma (POAG) undergoing phacoemulsification.

Patients And Methods: Safety and efficacy analyses involving the first 72 randomized eyes are included in this report. Following pre- (Screening) and post-medication washout (Eligibility) visits, one eye per subject was randomized 1:1 to STREAMLINE or iStent W after undergoing uncomplicated phacoemulsification.

Twelve-Month Outcomes of Stand-Alone Excisional Goniotomy in Mild to Severe Glaucoma.

Purpose: To describe 12-month intraocular pressure (IOP) and medication use outcomes following excisional goniotomy (EG) as a stand-alone procedure in eyes with medically uncontrolled glaucoma.

Methods: This was a retrospective analysis of data from surgeons at 8 centers (6 US, 2 Mexico). Eyes with glaucoma undergoing standalone EG with a specialized instrument (Kahook Dual Blade, New World Medical, Rancho Cucamonga, CA) for IOP reduction and followed for 12 months postoperatively were included.

Efficacy and safety of a single-use dual blade goniotomy: 18-month results.

Purpose: To compare the 18-month efficacy and safety of Kahook Dual Blade goniotomy (KDB) in combination with cataract surgery (combined group) or as a standalone procedure (standalone group).

Setting: Single surgeon practice.

Design: Retrospective review study.

12-Month Retrospective Comparison of Kahook Dual Blade Excisional Goniotomy with Istent Trabecular Bypass Device Implantation in Glaucomatous Eyes at the Time of Cataract Surgery.

Purpose: To compare the efficacy and safety of combined cataract extraction and either excisional goniotomy performed with the Kahook Dual Blade (KDB; phaco-KDB group) or single iStent trabecular bypass implantation (phaco-iStent group) in eyes with mild to moderate glaucoma and visually significant cataract.

Methods: This was a retrospective analysis of 315 eyes from 230 adults with mild or moderate glaucoma treated with one or more intraocular pressure (IOP)-lowering medications (190 eyes of 134 subjects in the phaco-KDB group and 125 eyes of 96 subjects in the phaco-iStent group) that required no subsequent surgical intervention for IOP control through 12 months of follow-up. Data included best-corrected visual acuity (BCVA), IOP, and IOP-lowering medications, collected preoperatively and at 1 week and 1, 3, 6, and 12 months postoperatively as well as intraoperative and postoperative adverse events.

Six-Month Outcomes of Goniotomy Performed with the Kahook Dual Blade as a Stand-Alone Glaucoma Procedure.

Introduction: To characterize the reduction in intraocular pressure (IOP) and IOP-lowering medication use following goniotomy via trabecular meshwork excision performed using the Kahook Dual Blade as a stand-alone procedure in adult eyes with glaucoma uncontrolled on a regimen of 1-3 topical IOP-lowering medications.

Methods: In this retrospective analysis, data from consecutive patients undergoing goniotomy with the Kahook Dual Blade by 11 surgeons were analyzed. Preoperative, intraoperative, and postoperative follow-up data through 6 months of follow-up were collected.

A multicenter retrospective comparison of goniotomy versus trabecular bypass device implantation in glaucoma patients undergoing cataract extraction.

Purpose: The aim of this study was to compare intraocular pressure (IOP) outcomes in eyes with cataract and glaucoma undergoing phacoemulsification (phaco) in combination with goniotomy using the Kahook Dual Blade (KDB) or implantation of a single iStent trabecular bypass device.

Methods: Retrospective analysis of IOP and IOP-lowering medication reduction in eyes undergoing phaco-goniotomy with KDB (n=237) or phaco-iStent (n=198). Preoperative, intraoperative, and postoperative data were collected through 6 months of follow-up.

Selective laser trabeculoplasty reduces mean IOP and IOP variation in normal tension glaucoma patients.

Purpose: To evaluate the effect of selective laser trabeculoplasty (SLT) in normal tension glaucoma (NTG) patients.

Patients And Methods: A retrospective review was performed of NTG patients who had undergone SLT at the Duke University Eye Center between 12/2002 and 7/2005. For each eye of each patient at pre-laser and post-laser time points, the IOP measurements were summarized by mean, standard deviation, and range.

Testicular mixed germ-cell tumor metastatic to the choroid.

Purpose: To describe the fundus findings, ultrasonography, and fluorescein angiography of a testicular mixed germ-cell tumor metastatic to the choroid and to report prompt resolution of the choroidal lesion with systemic chemotherapy.

Methods: Observational case report. A 21-year-old man presented with a 10-cm testicular tumor.

New ways to measure intraocular pressure.

Purpose Of Review: In the last 10 years, several new means to measure intraocular pressure have emerged. This review covers recent findings concerning four new technologies: the ocular response analyzer, dynamic contour tonometry, rebound tonometry and the Proview phosphene tonometer.

Recent Findings: The ocular response analyzer provides measurements of corneal biomechanics, including corneal hysteresis.

Filamentous fungal invasion of a methafilcon contact lens.

Purpose: To report a case of Fusarium species invasion of a methafilcon matrix soft contact lens in a first-time lens wearer.

Results: The authors describe the history and ocular examination of a 19-year-old woman with large fungal deposits on her contact lens. Culture of the contact lens grew Fusarium species.
