Blood vessels imaging typically requires a contrast dye. A new technology in optical coherence tomography (OCT) now enables blood vessels to be visualised without the use of chemical dye injected into the vein. This technique, OCT angiography (OCTA), is now available commercially and is used in routine clinics.
Lions Eye Institute had the first OCTA device in Australia and is leading research in this area. We are interested in validation of images acquired through OCTA and its use as clinical trials endpoint for diseases such as diabetic retinopathy and macular degeneration.
Undergraduate and postgraduate students and junior doctors can be involved in collecting patient images and data analysis. Our goal is to develop faster OCTA device and more accurate image analysis software to minimise motion and segmentation artefacts, which are major limitations in the current commercial systems.
