Eye movements and vision

The research group is interdisciplinary and consists of about 20 employees who divide their time between research, teaching and clinic. The group includes ophthalmologists, optometrists, orthoptists, computational linguists, psychologists, speech therapists and engineers. What unites us is the interest in increasing the understanding of how congenital and acquired diseases and damage to the eyes and the brain's visual system can be identified and how these affect different functions and abilitie

The research group is located at Marianne Bernadotte Center, Eye Center of Excellence and St. Erik Eye Hospital in Solna. The research in the group ranges from experimental models of humans and animals to clinical patient research. At our laboratory, we have several different methods for eye movement measurements and eye movements are extra exciting as eye movements have something to tell us about what vision does and how the brain works.

Research projects

Below are some examples of how our research has contributed to improved diagnosis and care for some of our patients – something we are incredibly proud of.

  • Through the development of a unique analysis method on reading eye movements, we managed to identify children with an increased risk of dyslexia with high precision while acquitting children with late reading development. The method of registration and analysis of reading eye movements and support in the assessment of dyslexia has since a few years been translated into a company Lexplore, which today is hired by several schools and municipalities in Sweden and many other countries.


  • A cerebral palsy affects the motor control in the body. How CP damage affects the eyes' ability to adjust sharpness when reading (accommodation) was not clear and we found in a study of 15 children with CP that the ability was severely affected. As a result, we learned that many people with cerebral palsy, regardless of severity, can get a lot of help from a pair of simple reading glasses when reading and working with the computer.


  • A head movement creates an eye movement response that depends on the brain's ability to integrate sensory information from several different senses. In a series of projects, we have mapped how head movements and image movements in the visual field are integrated and can also reveal different conditions that arise after brain injury.
