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).

Reduced Retinal Blood Vessel Densities Measured by Optical Coherence Tomography Angiography in Keratoconus Patients Are Negatively Correlated with Keratoconus Severity.

Keratoconus (KC) is the most common corneal ectasia. Optical coherence tomography angiography (OCT-A) is a relatively new non-invasive imaging technique that allows the visualization and quantification of retinal and choriocapillary blood vessels. The aim of this study is to assess retinal and choriocapillary vessel density (VD) differences between KC patients and healthy controls and to investigate correlations between VD and KC severity.

Methods: One hundred eyes from 100 patients with early glaucoma (mean deviation (MD): < -5.0 dB) and 100 eyes from 100 patients with moderate/advanced glaucoma (MD: > -5.

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.

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.

Primary Optic Disc Tumors - Case Series and Literature Overview.

Purpose: Primary optic disc tumors are often a challenge for ophthalmologists. They have very different appearances, and many primary optic disc tumors are associated with syndromic diseases (especially phakomatoses). Because of the rarity of primary optic disc tumors, classification and assessment are often difficult.

SALUS-a non-inferiority trial to compare self-tonometry in glaucoma patients with regular inpatient intraocular pressure controls: study design and set-up.

Purpose: The SALUS study aims to improve the healthcare situation for glaucoma patients in Germany. In order to detect diurnal intraocular pressure (IOP) fluctuations, inpatient monitoring of IOP in an eye hospital for a minimum of 24 h is the current standard. SALUS assesses the benefits of a new form of outpatient care, where IOP can be measured by the patients themselves at home using a self-tonometer.

[Corneal epithelial thickness in keratoconus patients compared to healthy controls].

Background: In keratoconus (KC) a progressive deformation and thinning of the cornea occurs. In contrast to Scheimpflug-based examinations, optical coherence tomography (OCT) can precisely measure the corneal layers separately, allowing separate analyses of corneal epithelial and corneal stromal thicknesses.

Aim Of This Work: The aim of this work was to analyze the corneal epithelial thickness measured by optical coherence tomography (OCT) in patients with KC in comparison to the corneal epithelial thickness in healthy subjects.

[Optical coherence tomography angiography (OCT-A) : Overview of the technique and the possible clinical and scientific applications].

Optical coherence tomography angiography (OCT-A) is a very promising noninvasive imaging modality. For the first time it enables a precise 3‑dimensional depiction of the retinal microcirculation without the use of contrast medium and can be carried out rapidly and simply. This makes OCT‑A interesting for both scientific and clinical applications.

[Optical coherence tomography angiography and cardiovascular diseases. An overview of the current knowledge].

Background: Cardiovascular diseases (CVD) are the leading cause of death worldwide. The observability of retinal vessel changes in the context of CVD by funduscopy has been known for a long time. Optical coherence tomography angiography (OCTA) is a novel technique for noninvasive detailed imaging and quantification of the retinal microcirculation.

[Choroidal neovascularization due to a punctate inner choroidopathy visualized by optical coherence tomography angiography].

Punctate inner choroidopathy (PIC) is often accompanied by the development of choroidal neovascularization (CNV). The identification of a fresh CNV in the context of PIC is often difficult. We present the case of a 30-year-old female patient with typical morphological features of PIC.

Impact of Working Experience on Image Perception and Image Evaluation Approaches in Stroke Imaging: Results of an Eye-Tracking Study.

Purpose:  Higher rates of missed pathologies, caused by a lack of professional experience or systematic search, suggest that a methodical approach to radiological analysis can be learned. Thus, the aim of this study is to investigate the efficiency of different principles of screening stroke CTs for cerebrovascular diseases between radiologists and neuroradiologists with different levels of experience in relation to professional experience.

Methods:  A set of anonymous CT images of 20 patients, with a suspected stroke, was individually presented to 12 radiologists with different levels of professional experience.

Lipofuscin-dependent stimulation of microglial cells.

Purpose: To examine the reaction of microglial cells (MG) when incubated with lipofuscin (LP) in vitro with emphasis on the immunological reaction of the MG toward LP and the suppression of this reaction by immunomodulatory agents. MG are involved in the pathogenesis of degenerative eye disorders such as age-related macular degeneration (AMD). LP is a heterogeneous waste material that accumulates in the retinal pigment epithelium (RPE) cells with advancing age.

Allergies - A T cells perspective in the era beyond the T1/T2 paradigm.

Allergic diseases have emerged as a major health care burden, especially in the western hemisphere. They are defined by overshooting reactions of an aberrant immune system to harmless exogenous stimuli. The T1/T2 paradigm assumes that a dominance of T2 cell activation and an inadequate T1 cell response are responsible for the development of allergies.
