Current Project

  • HiGHmed

  • Abstract

  • HiGHmed is working on novel, interoperable solutions in medical informatics with the aim to make medical patient data accessible for clinical research and education which will, in turn, improve patient care. Building safe data integration centres, the project aims to establish a technology platform enabling clinicians to take data-based and patient-centric decisions.

Previous Project

  • TOPOs - Therapy prediction through OCT and patient demography in ophthalmology

  • Abstract

  • Optical Coherence Tomography (OCT) has been a suitable diagnostic tool for ophthalmologists since many years. Pictures, taken from the latter part of the eye, the retina, and vertical depth scans of the macula allow reliable diagnostics of a variety of eye diseases as for example age-related macular degeneration, retinal vein occlusion or diabetic retinopathy. Up to today there are successful therapy methods, first of all the injection of anti - vascular endothelial growth factor (anti-VEGF) drugs. Nevertheless it seems not possible to this date, to reliably predict the correct amount of injections necessary as well as the time needed until the injection rate can be decreased or halted. In order to find remedy for this issue, this project unites experts of ophthalmology and visual analytics. The goal is, to explore the heterogenic multidimensional data of the OCT examinations in combination with the patients historical and personal characteristics. In adjunction with a specialized visualization tool for ophthalmologists, the possible causes and/or influencing factors for the therapy of retinal diseases are expected to crystalize from the data.
