The optical coherence tomography and microperimetry biomarker evaluation in patients with geographic atrophy (OMEGA) study: Geographic atrophy progression in fundus autofluorescence—OMEGA report 3.
Abstract Purpose To measure the progression of geographic atrophy (GA) in subjects with age-related macular degeneration (AMD) in a natural history study. Methods We analysed fundus autofluorescence (FAF) images using a semiautomatic method (RegionFinder) to quantify...
Imaging: neue Techniken zur Bildgebung des Glaskörpers (Imaging: New Techniques for Vitreous Imaging).
Zusammenfassung Diese Übersichtsarbeit adressiert das zentrale Problem, dass der Glaskörper – obwohl er rund 80 % des okulären Volumens ausmacht – aufgrund seiner Transparenz klinisch oft nur unzureichend beurteilt werden kann. Diese Arbeit hebt damit die...
Regional differences in foveal avascular zone morphology in cynomolgus macaques using a normative OCTA database
Abstract Cynomolgus macaques are widely used in preclinical ophthalmic research because of their close anatomical and physiological similarity to the human eye. However, the small cohort sizes typical of laboratory studies and the limited implementation of automated...
Deep generative models for enhanced vitreous OCT imaging
Abstract The aim of the work is to evaluate deep learning (DL) models for enhancing vitreous optical coherence tomography (OCT) image quality and potentially reducing acquisition time. Conditional Denoising Diffusion Probabilistic Models (cDDPMs), Brownian Bridge...
