Effectiveness and safety of XEN63 in patients with primary-open-angle glaucoma.

This paper evaluates the effectiveness and safety of XEN63 stent, either standalone or in combination with phacoemulsification, in patients with primary open-angle glaucoma (POAG). Eighty eyes from 80 patients with medically uncontrolled POAG were assigned to undergo XEN63 implant. The primary outcome was the surgical success, defined as an intraocular pressure (IOP) lowering from preoperative values ≥ 20% and an IOP absolute value between 6 and 18 mmHg, with or without antiglaucoma medications.

Association of retinal neurodegeneration with the progression of cognitive decline in Parkinson's disease.

Retinal thickness may serve as a biomarker in Parkinson's disease (PD). In this prospective longitudinal study, we aimed to determine if PD patients present accelerated thinning rate in the parafoveal ganglion cell-inner plexiform layer (pfGCIPL) and peripapillary retinal nerve fiber layer (pRNFL) compared to controls. Additionally, we evaluated the relationship between retinal neurodegeneration and clinical progression in PD.

Short-term effectiveness prognostic factors after dexamethasone intravitreal implant in macular edema due to retinal vein occlusion.

Introduction: The aim of this study was to describe functional and anatomical changes (best-corrected visual acuity [BCVA], central macular thickness [CMT], and central macular volume [CMV]) in patients with macular edema (ME) secondary to retinal vein occlusion (RVO) treated with intravitreal dexamethasone implant (IDI) and identify its clinical predictors in a real-world setting.

Methods: Data from 111 patients who underwent IDI to treat RVO-associated ME were retrospectively reviewed. Demographic, preoperative, and postoperative variables were assessed using a logistic regression analysis to determine predictors of visual and anatomical improvement.

Safety and efficacy of bilateral simultaneous XEN implant surgery: a pilot study.

Objective: To evaluate the efficacy and safety of the bilateral simultaneous XEN (BISIXEN) surgery in open-angle glaucoma patients.

Methods: Retrospective analysis of a prospective data base conducted on uncontrolled glaucoma patients who underwent BISIXEN surgery. Primary endpoint measure was the incidence of sight-threatening complications.

Optimization of a Method to Isolate and Culture Adult Porcine, Rats and Mice Müller Glia in Order to Study Retinal Diseases.

Müller cells are the predominant glial elements in the retina, extending vertically across this structure, and they fulfill a wealth support roles that are critical for neurons. Alterations to the behavior and phenotype of Müller glia are often seen in animal models of retinal degeneration and in retinal tissue from patients with a variety of retinal disorders. Thus, elucidating the mechanisms underlying the development of retinal diseases would help better understand the cellular processes involved in such pathological changes.

Update on the usefulness of optical coherence tomography in assessing the iridocorneal angle.

The iridocorneal angle, due to its implications in the physiopathology of aqueous humour drainage, is a fundamental structure of the anterior chamber. Anterior segment optical coherence tomography is a rapid and non-invasive technique that obtains images in vivo. The high resolution allows it to analyse the normal anatomy of the angle, any alterations, and the changes that occur after different therapeutic interventions.
