Imaging plays an indispensable role in clinical care in ophthalmology, ranging from diagnostics to risk stratification and treatment monitoring. Imaging biomarkers were identified in many eye diseases such as glaucoma, diabetic retinopathy (DR), and age-related macular degeneration (AMD).
Headed by Professor Leopold Schmetterer, the Ocular Imaging Research Group aims to develop a strong network of shared platforms that will improve patient care, allow for multicentre trials, and will foster collaborations in several research themes spanning from posterior pole applications towards corneal OCT angiography.
Clinical studies on the use of optical coherence tomography angiography (OCT-A) in patients with glaucoma, DR and AMD
Evaluation of novel imaging biomarkers in high myopia
Use of ultrahigh-resolution OCT techniques for the characterisation of the corneal and ocular surface disease
Use of novel anterior segment OCT techniques to image glaucoma
Studying the structure-function relationship in ocular disease
Establishment of imaging parameters as surrogate outcomes for clinical studies
Quantification of blood flow in the micro-vasculature using Doppler OCT and OCT-A
Validation of OCT-A technology in experimental animal models
Development of novel ultrahigh-resolution OCT technology
Multi-beam OCT approaches for retinal imaging
Multimodal retinal imaging
Assessment of tear film dynamics using OCT
OCT elastography to study biomechanical properties of tissue
Modelling of retinal and choroidal blood flow
Metabolic retinal imaging
Laser speckle technology to study ocular perfusion
Studying Ca2+ transport and neurovascular coupling in an animal model of glaucoma
