Automated detection and quantification of intraretinal exudative cysts in macular edema using OCT.
Project summary
Optical coherence tomography (OCT) is a non-invasive fundus imaging technique. OCT is particularly useful for monitoring the spontaneous evolution or post-treatment progression of chronic macular diseases such as diabetic maculopathy or age-related macular degeneration (AMD). These two diseases affect several million people worldwide and cause blindness in many cases. In addition to visual acuity tests, an Optical Coherence Tomography (OCT) examination is a great advantage when treating patients. If the central macular thickness (CMT) increases and/or some intra retinal cysts are noted, it is recommended to treat patients. The overall aim of the work is to provide automated computer vision techniques that can be applied to OCT images to assist clinicians to base treatment decisions on quantitative information to achieve better patient outcomes. The clinical aims of the work can be summarised: • Automatically recognise intra-retinal cysts on OCT images. • Quantify the volume of the intra-retinal cyst with respect to the retinal tissue itself. • Quantify the change in the volume of the cyst over time.
