Visualization of the Postoperative Position of the Hydrus Microstent Using Automatic 360° Gonioscopy.

: Glaucoma, one leading cause of irreversible vision loss worldwide, is primarily caused by elevated intraocular pressure (IOP). Recently, minimally invasive glaucoma surgeries (MIGSs) have become popular due to their shorter surgical times, tissue-sparing nature, and faster recovery. One such MIGS, the Hydrus nickel-titanium alloy Microstent, helps lower IOP by improving aqueous humor outflow.

Microvascular Density Analysis of Patients with Inactive Systemic Lupus Erythematosus-A Two-Year Follow-Up Optical Coherence Tomography Angiography Study.

This study aims to investigate the long-term effect of inactive systemic lupus erythematosus (SLE) on the retinal microcirculation measured via optical coherence tomography angiography (OCT-A). Twenty-four eyes of 24 patients with inactive SLE under hydroxychloroquine (HCQ) therapy were included. The OCT-A data (mainly vessel density (VD) and foveal avascular zone (FAZ) data of the superficial and of the deep capillary plexus (SCP, DCP) and the choriocapillaris (CC)) were analyzed and compared between the baseline examination (t) and 2 years later (t).

Retrospective Analysis of Bicanalicular Lacrimal Silicone Tube Intubation in Patients with Congenital Nasolacrimal Duct Obstruction: A Long-term Follow-up Study.

Congenital nasolacrimal duct obstruction (CNLDO) is the most common cause of epiphora in the first year of life. In addition to conservative therapy, there are several invasive methods available. The aim of this retrospective study was to conduct a long-term follow-up of bicanalicular lacrimal duct intubation as the primary intervention in a large cohort of patients with CNLDO.

[Effects of Susac syndrome on the central vascular structure of the retina-An optical coherence tomography angiography study].

Background: Susac syndrome (SS) describes an endotheliopathy of vessels in the central nervous system. Retinal involvement plays a central role in the manifestation of the disease.

Objective: This case-control study investigated the macular microvasculature in patients with chronic SS compared to controls using optical coherence tomography angiography (OCTA).

[Frequency and distribution of the active agent of intravitreal injections in German centers 2015-2021-An oregis study].

Introduction: Digitalization in medicine, especially the electronic documentation of patient data, is revolutionizing healthcare systems worldwide. The evaluation of real-world data collected under everyday conditions presents opportunities but also challenges. Electronic medical registries provide a means to compile extensive patient data for scientific inquiries.

The Preserflo MicroShunt Affects Microvascular Flow Density in Optical Coherence Tomography Angiography.

Intraocular pressure (IOP) lowering surgery has been shown to alter microvascular density in glaucoma patients. The aim of this study is to report changes in retinal flow density (FD) over the course of treatment with the Preserflo MicroShunt, using optical coherence tomography angiography (OCTA). 34 eyes from 34 patients who underwent Preserflo MicroShunt implantation were prospectively enrolled in this study.

Acute Idiopathic Blind Spot Enlargement Syndrome (AIBSES) in the Era of OCT - a Review.

There are only about 100 case reports on the Acute Idiopathic Blind Spot Enlargement Syndrome (AIBSES). This is characterised by the eponymous visual field loss in the blind spot area, acute onset photopsia, and funduscopically little or no change in the optic disc area, with conspicuous outer retinal bands on optical coherence tomography (OCT). Typical is the unilateral occurrence.

Position of the ISTENT Inject Trabecular Micro-Bypass System Visualized with the NIDEK GS-1 Gonioscope-A Postoperative Analysis.

Glaucoma is one of the leading causes of irreversible blindness globally and is characterized by the gradual loss of retinal ganglion cells. The primary risk factor for the development and progression of glaucoma is increased intraocular pressure (IOP). Numerous surgical interventions exist to lower IOP should conservative therapy fail.

Characterizing Foveal Hypoplasia Using Optical Coherence Tomography Angiography: Evaluation of Microvascular Abnormalities and Clinical Significance.

This study aimed to evaluate foveal avascular zone (FAZ) features and macular flow density (FD) in various retinal layers in a cohort of patients with foveal hypoplasia (FH) using optical coherence tomography angiography (OCTA), in order to characterize microvascular abnormalities and explore their potential clinical significance. FAZ parameters and FD, as well as retinal thickness and volume values were analyzed and compared between patients with FH and an age- and gender-matched control cohort. Correlations between disease severity and visual acuity (VA), as well as between disease severity and FAZ features were evaluated.

Long-Term Outcomes of the PRESERFLO MicroShunt Implant in a Heterogeneous Glaucoma Cohort.

The Preserflo MicroShunt represents a novel glaucoma treatment device, necessitating long-term follow-up data to accurately assess its efficacy. The aim of this study is to report real-world data of a heterogenous glaucoma cohort who received Preserflo implantation at a specialized glaucoma clinic. A total of 160 eyes of 160 patients who underwent Preserflo MicroShunt implantation were retrospectively enrolled in this study.

FURTHER EVIDENCE AGAINST BILATERAL MANIFESTATION OF COATS DISEASE IN OPTICAL COHERENCE TOMOGRAPHY ANGIOGRAPHY OF THE MACULA.

Purpose: Recent studies have questioned the traditional view, which regards Coats disease as a strictly unilateral entity. Applying optical coherence tomography angiography, this prospective, monocentric study investigates quantitative capillary changes of the macula associated with Coats disease.

Methods: Twenty-four eyes (4 untreated, 8 pre-treated) of 12 patients with stage 2 Coats disease (age range: 9-61 years) and 15 eyes of healthy, age-matched controls from the University of Muenster Medical Center, Germany received macular optical coherence tomography angiography measurements of the superficial, deep, and choriocapillary capillary plexus.

Nasolacrimal intubation in transcanalicular endoscopic dacryoplasty: a long-term follow-up study.

Nowadays, transcanalicular endoscopic dacryoplasty represents the majority of lacrimal duct surgery procedures performed in adults in specialised centers. However, there are still hardly any data available regarding the intra- and postoperative care, particularly regarding the duration of silicone tube intubation (STI). Our aim was to evaluate the relation between tube duration and recurrence of symptoms in patients who underwent transcanalicular microdrill dacryoplasty (MDP) in a long-term setting.

Influence of Cilioretinal Arteries on Flow Density in Glaucoma Patients Measured Using Optical Coherence Tomography Angiography.

It has long been speculated whether the presence of a cilioretinal artery (CRA) can influence the development of glaucomatous damage in patients with open-angle glaucoma. Studies involving healthy patients have shown a change in flow density (FD) depending on the presence of a CRA. Similarly, studies that compared the optical coherence tomography angiography (OCTA) results of healthy controls and glaucoma cohorts identified a reduction in FD in certain retinal layers for glaucoma patients.

Retinal microvascular density analysis in patients with rheumatoid arthritis treated with hydroxychloroquine.

Purpose: Rheumatoid arthritis (RA) is the most common inflammatory joint disease, and hydroxychloroquine (HCQ) is an established treatment. The extent to which HCQ impacts ocular microvascular vessel density (VD) in patients with RA without evidence of HCQ retinopathy has not yet been conclusively clarified. The main aim of this study was to evaluate VD measured by optical coherence tomography angiography (OCTA) in patients with RA treated with HCQ.

Long-Term Outcomes of Canaliculotomy with Silicone Tube Intubation in the Management of Canaliculitis.

As a rare and often misdiagnosed disease of the lacrimal apparatus, only limited data exist on long-term outcomes of surgical methods for the treatment of primary canaliculitis. The aim of this study was to evaluate canaliculotomy with silicone tube intubation (STI) as a surgical procedure for canaliculitis in a long-term follow-up setting. A total of 25 eyes of 25 patients with canaliculitis treated with canaliculotomy and STI at the University of Muenster Medical Center, Germany, from 2015 to 2021 were included in this study.
