Matched case-control comparison of surgical success after XEN45 Gel Stent and PRESERFLO MicroShunt implantation in a Caucasian population.

Background: The aim of this study was to compare the outcome of implantation of a XEN45 Gel Stent with the outcome of implantation of a Preserflo MicroShunt in a matched-pair analysis in eyes being naïve to filtering surgery.

Methods: In this comparative, retrospective study, 50 eyes that had undergone XEN45 Gel Stent implantation were compared with 50 eyes after Preserflo implantation. Follow-up was at least 6 months, and surgical success was measured by criteria A (IOP < 21 mmHg, IOP reduction >20%, no repeat surgery); criteria B (IOP < 18 mmHg, IOP reduction >20%, no repeat surgery); and criteria C (IOP ≤15 mmHg, IOP reduction ≥40%, no repeat surgery).

Combined versus standalone XEN45 Gel Stent implantation in either phakic or pseudophakic patients: a case-matched study.

Purpose: To determine differing outcomes among either phakic or pseudophakic patients who received standalone XEN45 Gel Stent (Allergan, an AbbVie Company, CA, USA) implantation and patients who underwent combined surgery with phacoemulsification.

Methods: This retrospective single-center study involved 180 eyes of 180 participants who underwent XEN45 Gel Stent implantation, of which 60 eyes received combined surgery with phacoemulsification (combined group). Standalone stent implantation was performed on 60 phakic (phakic group) and on 60 pseudophakic eyes (pseudophakic group).

Predictability of success for combined iStent inject trabecular bypass implantation with phacoemulsification in the subsequent eye.

Background: To investigate in combined iStent inject implantation with phacoemulsification carried out bilaterally, whether intraocular pressure (IOP)-lowering effectiveness in the first eye has a predictive potential for the outcome of the second eye in primary open-angle glaucoma (POAG).

Methods: This retrospective study included 72 eyes from 36 participants, who underwent trabecular bypass implantation in combination with cataract surgery at two study centres (Düsseldorf, Cologne). Surgery was classified as either 'success' or 'failure' based on three scores: IOP at follow-up <21 mmHg (Score A) or IOP < 18 mmHg (Score B), with an IOP reduction >20% respectively, without re-surgery and IOP ≤ 15 mmHg with an IOP reduction ≥40%, without re-surgery (Score C).

TREATMENT OF PERSISTENT MACULAR HOLES WITH HEAVY SILICONE OIL.

Background/purpose: To determine anatomical success and best-corrected visual acuity after secondary surgery with heavy silicone oil tamponade in patients with persistent full-thickness macular holes.

Methods: In this retrospective study, 63 eyes with persistent full-thickness macular holes after primary pars plana vitrectomy and internal limiting membrane peeling underwent secondary surgery with heavy silicone oil tamponade. Macular spectral domain optical coherence tomography and best-corrected visual acuity measurements were performed during the follow-up.

BioAdhere: tailor-made bioadhesives for epiretinal visual prostheses.

: Visual prostheses, epiretinal stimulating arrays, are a promising therapy in treating retinal dystrophies and degenerations. In the wake of a new generation of devices, an innovative method for epiretinal fixation of stimulator arrays is required. We present the development of tailor-made bioadhesive peptides (peptesives) for fixating epiretinal stimulating arrays omitting the use of traumatic retinal tacks.

Predictability of success and open conjunctival revision rates in the subsequent eye after XEN45 Gel Stent implantation according to lens status.

Purpose: To determine the predictability of success and the risk of open conjunctival revision in the subsequent eye after XEN45 Gel Stent implantation according to lens status.

Methods: This was a retrospective single-centre study involving 132 eyes of 66 participants who had undergone intraocular pressure (IOP)-lowering XEN45 Gel Stent implantation, either as a standalone procedure in phakic and pseudophakic eyes or in combination with phacoemulsification. Successful surgery was defined by three scores: IOP at follow-up < 21 mmHg (score A) or < 18 mmHg (score B) and an IOP reduction > 20% or IOP ≤ 15 mmHg and an IOP reduction ≥ 40% (score C).

Impact of failed ab-interno trabeculectomy (trabectome) on subsequent XEN45 gel stent implantation in pseudophakic eyes.

Purpose: To determine the impact of failed ab-interno trabeculectomy on the postoperative outcome of subsequent XEN45 gel stent (Allergan, CA, USA) implantation in pseudophakic eyes.

Methods: In this retrospective single-center study, we included 60 pseudophakic eyes from 60 participants who underwent XEN45 gel stent implantation. Thirty eyes each underwent primary stent implantation (control group) or had previously undergone a failed ab-interno trabeculectomy (trabectome group).

A Case of Endocarditis Following Endophthalmitis After XEN45 Gel Stent Implantation.

Introduction: We report a case of endophthalmitis and endocarditis that developed after stent perforation following a XEN45 Gel Stent implantation 10 months ago.

Thirty-two eyes received surgery while under anticoagulation therapy, and another thirty-two eyes served as a control group matched for visual acuity, IOP, and medication score.

The Third Annual Thomas S. Tenforde Topical Lecture HPS Ask the Experts: The Most Intriguing Questions and Answers.

The Health Physics Society (HPS) conceived of the idea of an online "Ask the Experts" (ATE) feature in 1999 when the Society created its website. ATE features are popular now, but at that time it was a novel idea, so there was no assurance it would succeed. Now 20 y later, the HPS considers its ATE feature a success and the most valuable service the Society offers for the public.

Presidential Perspectives: Women's Views From the Top.

This paper presents the perspectives of past presidents of the Health Physics Society who also happen to be women. Only 6 out of 63 Society presidents have been women, and of these six, five are still living and briefly reflect on their experiences here, alongside a brief discussion of the first female president of the Society. These perspectives provide historical insight into the evolution and happenings of the Society as well as adding personal touches to the office of the president that hopefully will encourage junior Society members to consider serving.

Long-term follow-up after implantation of a telemetric intraocular pressure sensor in patients with glaucoma: a safety report.

Importance: To investigate the long-term safety of a novel intraocular telemetric pressure sensor.

Background: Acquisition of accurate intraocular pressure (IOP) data is vital for sufficient medical care of glaucoma patients. Non-invasive self-tonometry with a telemetric IOP sensor can provide important information regarding the individual IOP profile.

The effect of additional trabecular aspiration to phacoemulsification and trabectome as a triple procedure in pseudoexfoliation glaucoma: a case-matched study.

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.
