Comparison between Findings in Optical Coherence Tomography Angiography and in Fluorescein Angiography in Patients with Diabetic Retinopathy.

Objective: To compare typical findings of diabetic retinopathy in optical coherence tomography angiography (OCTA) and fluorescein angiography (FA).

Subjects/methods: 42 patients were enrolled in this study. We performed FA and obtained en face 3 × 3 mm OCTA images of the macular region.

[Augmented Reality in Ophthalmology: Technical Innovation Complements Education for Medical Students].

Background: At the Medical Faculty of the University of Ulm, the learning objectives of ophthalmology are taught to students in a one-week block course in the fourth year of study. According to the National Competency-based Learning Objective Catalogue Medicine (NKLM), one of these learning objectives is the clinical examination of the eye, including the eye fundus examination. In order to best train this expertise as defined in the NKLM, a novel, augmented reality-based training simulator (Eyesi Indirect, VRmagic Holding AG, Mannheim, Germany) was integrated into the teaching at the University Eye Hospital Ulm.

Quantity and quality of image artifacts in optical coherence tomography angiography.

Objective: To analyze quality and frequency of OCTA artifacts and to evaluate their impact on the interpretability of OCTA images.

Design: 75 patients with diabetic retinopathy (DR), retinal artery occlusion (RAO), retinal vein occlusion (RVO), or neovascular age-related macular degeneration (nAMD) and healthy controls were enrolled in this cross-sectional study in the outpatient department of a tertiary eye care center.

Methods: All participants underwent an OCTA examination (spectral domain OCT Cirrus 5000 equipped with the AngioPlex module).

[Innovative Teaching Methods: Wet Lab-based Ophthalmosurgical Education for Medical Students].

Background: An increased demand for young physicians in Germany is causing increased competition to attract the best minds, even during their undergraduate studies. Therefore, it is the task of the university hospitals to offer their students the best possible courses in order to arouse interest in the relevant subject area. We therefore examined the impact of an ophthalmosurgical wet lab on teaching undergraduate medical students.

[Novel Examination Procedures for the Assessment of Retinal Artery Occlusion by OCT Angiography].

Retinal artery occlusion (RAO) is the most common primary angiopathy of the retina. With an incidence of 0.01 - 0.

[Accurate OCT-angiography Interpretation - Detection and Exclusion of Artifacts].

Optical coherence tomography angiography (OCTA) provides, non-invasively, a three-dimensional visualization of the microvasculature of the retina and choroid. However, image artifacts may occur in OCTA and have an impact on clinical interpretation. The aim of this article is to describe image artifacts of OCTA and to present a nomenclature.
