Project Description

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.

In this 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, leading to complications such as vision loss and, ultimately, blindness. Detecting the onset of retinal hypoxia will allow timely therapeutic interventions to prevent vision loss.

In this collaborative project between VU Amsterdam, TNO, and Heidelberg Engineering, we will develop a multi-color scanning laser ophthalmoscope (mcSLO)-based oximeter with retro-illumination capabilities. The retro-mode mcSLO will be a versatile research tool, providing freedom in selecting imaging wavelengths and allowing different implementations of light delivery and collection to and from the retina. We will develop novel image analysis algorithms for retro-mode imaging to quantify the wavelength-dependent scattering and absorption properties of the retina, from which microvascular oxygen saturation can be calculated. The algorithms will partly rely on Monte Carlo simulations of light transport in the retina. The system and algorithm performance will be validated on model eyes with controlled scattering and absorption properties.

Tasks

We are looking for a PostDoc who will:

• Work on optical instrumentation, image analysis algorithms, and technical validation on model eyes

• Develop a retro-mode illumination and detection module and integrate it into an existing custom-built mcSLO system

• Perform tests on model eyes and analyze the results as a first technical validation of the system

The research will be conducted at VU Amsterdam. The candidate will be part of the Biomedical Physics Group, under the supervision of Prof. dr. J.F. de Boer and Prof. dr. A. Amelink.
