Purpose: To evaluate the effects of exercise on optic nerve and macular perfusion using optical coherence tomography angiography. Methods: Thirteen eyes 13 healthy volunteers were examined a high-speed high-resolution spectral-domain XR Avanti with split-spectrum amplitude-decorrelation angiography algorithm. Blood pressure, heart rate, mean area foveal avascular zone , flow density head macula, before after measured analyzed. Results: Mean patient age was 27.3 ± 3.5 years. Heart systolic...
To evaluate a deep learning-based method to automatically detect graft detachment (GD) after Descemet membrane endothelial keratoplasty (DMEK) in anterior segment optical coherence tomography (AS-OCT).In this study, total of 1172 AS-OCT images (609: attached graft; 563: detached graft) were used train and test convolutional neural network GD DMEK surgery images. was defined as not completely graft. After training with 1072 these (559: 513: graft), the created classifier tested remaining 100...
Brain-computer interfaces based on event-related potentials face a trade-off between the speed and accuracy of system, as both depend number iterations. Increasing iterations leads to higher but reduces system. This is generally dealt with by finding fixed that give good result calibration data. We show here this method sub optimal increases performance significantly in only one out five datasets. Several alternative methods have been described literature, we test generalization four them....
<b><i>Purpose:</i></b> To evaluate choriocapillaris (CC) perfusion in healthy subjects using 2 different optical coherence tomography angiography (OCT-A) devices. <b><i>Procedures:</i></b> Macular OCT-A imaging (36 eyes of 36 subjects) was performed Optovue AngioVue and Zeiss AngioPlex CC decorrelation signal index assessed, data were analyzed regarding intra-device variability, inter-device correlation, age, strength, fields view....
Abstract Purpose The present retrospective study was designed to test the hypothesis that postoperative posterior preoperative anterior corneal curvature radii (PPPA) ratio in eyes with Fuch’s dystrophy undergoing Descemet membrane endothelial keratoplasty (DMEK) is significantly different (PA) virgin and therefore renders conventional keratometry (K) power derived by it invalid for intraocular lens (IOL) calculation. Methods Measurement of parameters performed using Scheimpflug imaging...
To evaluate the utility of intraocular lens (IOL) power calculation using adjusted conventional keratometry (K) according to postoperative posterior preoperative anterior corneal curvature radii (PPPA) ratio for eyes with Fuch's dystrophy undergoing cataract surgery combined Descemet membrane endothelial keratoplasty (triple DMEK).A fictitious refractive index (FRI) was determined (Pentacam HR®) based on PPPA in 50 triple DMEK. Adjusted calculated every eye K values: values by IOLMaster were...
Zusammenfassung Hintergrund Die vorliegende Studie vergleicht die Ausprägung von Bewegungsartefakten bei Aufnahmen der optischen Kohärenztomografie-Angiografie (OCT-A) gesunden Probanden zwischen 2 OCT-A-Systemen verschiedener Hersteller mit unterschiedlicher technischer Ausstattung. Methodik In dieser Arbeit wurden 25 Augen (19 weiblich, mittleres Alter 31,12 ± 11,95 Jahre) ohne bestehende Augenerkrankungen oder zurückliegende Augenoperationen eingeschlossen. OCT-A-Aufnahmen dem RTVue XR...
The aim of this study was to use deep learning based on a convolutional neural network (DCNN) for automated image classification healthy optic discs (OD) and visible disc drusen (ODD) fundus autofluorescence (FAF) color photography (CFP). In study, total 400 FAF CFP images patients with ODD controls were used. A pre-trained multi-layer Deep Convolutional Neural Network trained validated independently images. Training validation accuracy cross-entropy recorded. Both generated DCNN classifiers...
Abstract Slowing is a common feature of ageing, yet direct relationship between neural slowing and brain atrophy to be established in healthy humans. We combine magnetoencephalographic (MEG) measures processing speed with magnetic resonance imaging (MRI) white- gray-matter large (N=617, 18-88yrs), population-derived cohort ( www.cam-can.org ) investigate the age-related structural differences VEF AEF delay across two different tasks. Using novel technique, we show that VEFs exhibit constant...
To analyze the influence of a cilioretinal artery (CRA) on macular and peripapillary vessel density in healthy eyes as measured using optical coherence tomography angiography.A total 83 patients were included this study. Optical angiography was performed RTVue XR Avanti with AngioVue (Optovue Inc). The macula imaged 3 × 3-mm scan, whereas for optic nerve head 4.5 4.5-mm scan taken. images screened presence CRA.In 31 eyes, CRA detected (37.3%). significantly lower within (P = 0.005) but...
Zusammenfassung Die altersabhängige Makuladegeneration (AMD) ist der führende Grund für Erblindung in westlichen Welt. Für die neovaskuläre Verlaufsform steht mit intravitrealen Anti-VEGF-Injektion (VEGF: vascular endothelial growth factor) eine wirksame Therapie zur Verfügung. In den letzten Jahren haben multimodale Bildgebung und standardisierte elektronische Patientendokumentation geholfen, Diagnostik das Management AMD-Patienten zu verbessern. Mit dem Aufkommen künstlichen Intelligenz...
