About the Project

Due to ageing, the impact of vision threatening diseases such as diabetic retinopathy (DR) and age-related macular degeneration (AMD) on the health care system will only increase.

Within a joint TNO/VU TKI project we will develop techniques to quantitatively assess the oxygen saturation status of the retinal microvasculature. Reduced blood oxygen levels may lead to hypoxia, which is one of the key drivers of the formation of new blood vessels. These new blood vessels are often leaky, which leads to complications such as vision loss and, ultimately, to blindness. The development of techniques to detect the onset of retinal hypoxia will thus allow timely therapeutic interventions that will prevent vision loss.

In this project, we will develop a multi-color scanning laser ophthalmoscope (mcSLO)-based oximeter. The mcSLO will be a versatile research tool that provides freedom in the selection of imaging wavelengths and allows different implementations of light delivery and collection to and from the retina. For the image analysis we will develop novel oximetry algorithms. The performance of the system and algorithms will be validated on model eyes with flow channels containing blood of controlled flow velocity and oxygen saturation. Clinical pilot studies of DR patients, AMD patients and healthy volunteers will be performed to demonstrate local variations in retinal oxygenation between DR, AMD and healthy retinas.

For this project, we are looking for a PhD student who will work on the optical instrumentation, the model eye development, the oximetry algorithm development and on the technical and clinical validation. The research will be conducted at 2 locations, TNO in Delft and VU in Amsterdam. The candidate will be part of the PhD program of the Biomedical Physics Group of the VU, under joint supervision of Prof. dr. A. Amelink and Prof. dr. J.F. de Boer.

About the Department

The Faculty of Science inspires researchers and students to find sustainable solutions for complex societal issues. From forest fires to big data, from obesity to medicines and from molecules to the moon: our teaching and research programmes cover the full spectrum of the natural sciences. We share knowledge and experience with leading research institutes and industries, both here in the Netherlands and abroad.

Working at the Faculty of Science means working with students, PhD candidates and researchers, all with a clear focus on their field and a broad view of the world. We employ more than 1,250 staff members, and we are home to around 6,000 students.

The Department of Physics and Astronomy at VU Amsterdam offers an active and engaged intellectual community composed of researchers from around the world. Research is focused on four themes: (i) high-energy and gravitational physics, (ii) quantum metrology and laser applications, (iii) physics of life and health, and (iv) physics of photosynthesis and energy. The department is involved in teaching in the programs Physics and Astronomy (joint degree with the University of Amsterdam), Science Business and Innovation, Medical Natural Sciences (all three BSc and MSc), and the BSc program in Mechanical Engineering (together with University of Twente). Furthermore, the department has a strong track record in valorization of its research, including translational research to the clinic (often together with the Amsterdam UMC, location VUmc (on campus) and location AMC), collaborations with industry (e.g. ARCNL), and a thriving startup scene.
