What is the background of the project?
Glare by the low sun or the headlights of oncoming cars is a common challenge experienced by drivers. In Belgium, about 1.6% of accidents and 2.6% of all road fatalities are related to glare. Glare is caused by light that is scattered within the eye, called straylight. Ideally, light entering the eye would pass undisturbed through all ocular structures to form a perfect image on the retina. The ocular media are not optically ideal, however, and contain many particles that cause a fraction of the light to scatter, forming a veil of light over the retinal image. This straylight, which is known to increase with age and diseases such as cataract, causes a substantial reduction in visual quality. Having a high straylight value increases the risk of traffic accidents, yet it is not clear what level of straylight can still be considered safe. This project proposes the use of data from a state-of-the-art driving simulator to analyze the driving capacity of healthy subjects under the disturbance of a glare source. Based on this data an analysis of straylight in pathological groups (e.g. diabetes, glaucoma, etc.) can also be done. This will allow a better understanding of the complex interaction between driving capability and visual quality in the general population, providing a vital upgrade of visual standards for drivers. This, in turn, will lead to safer roads and will help reduce the high socio-economic burden of traffic accidents.
What is the aim of the project?
Determine evidence-based cut-off value for straylight in the driving population
What techniques and methods are used?
Step 1: Assess the influence of straylight on driving capacity in the general driving population. Method and material: use of a driving simulator, vision tests and straylight measurement (currently ongoing) Step 2: Assess the influence of straylight on vision in pathological groups (glaucoma, diabetes and uveitis) Method and material: questionnaires on driving ability, vision tests, and straylight measurements Step 3: Create guidelines for straylight safety in the driving population The student will be asked to help with Step 2
What is the role of the student?
- The tasks of the student will be performed on his/her own
- The tasks will be done under supervision
What are the tasks expected to be accomplished by the student?
Patient data collection at the Antwerp University Hospital: Recruit patients from the consultation and obtain their informed consent, Taking questionnaires on the quality of vision, Perform straylight measurements, Perform basic vision tests (letter chart, refraction, dominance, etc.), Insert data into a dedicated database, Perform part of the data-analysis (if the student is interested and the timing permits it)
Will there be any theoretical teaching provided (preliminary readings, lectures, courses, seminars etc)
Yes. Direct one-on-one tutoring by the study supervisor (J. Rozema) at the beginning of the project and as needed after that.
What is expected from the student at the end of the research exchange? What will be the general outcome of the student?
- The student’s name will be mentioned in a future publication
What skills are required of the student? Is there any special knowledge or a certain level of studies needed?
Basic computer skills (Microsoft Office)
Are there any legal limitations in the student’s involvement
