Visual disorders resulting from acquired brain injuries frequently hinder daily activities and diminish quality of life. Tony Pansell, a newly appointed professor at Karolinska Institutet, is investigating methods to improve vision through targeted rehabilitation techniques. Pansell will be recognized during the installation ceremony at Aula Medica on October 9, 2025.
Research Focus on Neuro-Optometry
Pansell’s work centers on the field of neuro-optometry, examining how vision and eye movement control are impacted by brain injuries. His research aims to develop effective rehabilitation strategies that incorporate vision training and customized optical solutions for patients. A particularly informative group in this study has been individuals recovering from concussions, who often demonstrate a rapid healing process and a strong motivation to engage in vision rehabilitation. Insights gained from this demographic have been beneficial for those with various other types of brain injuries.
Pansell emphasizes the significance of vision in everyday life, stating, “Good vision is not only needed for reading and writing, but also for maintaining balance, moving about, eating and recognizing people.” He notes that vision relies on the interplay of multiple functions, including healthy visual pathways, motor control, and cognitive abilities.
Key Findings and Implications
Pansell’s research has yielded important findings regarding the effects of brain injuries on vision. His studies indicate that individuals often experience greater challenges with near vision compared to distance vision following such injuries. Symptoms may include eye strain, blurred vision, and a disorienting sensation where letters appear to move while reading. Another notable issue is visual vertigo, a hypersensitivity to motion in one’s visual field, particularly in busy environments or while using electronic devices.
According to Pansell, “Our patients often have a combination of disorders. Vision disorders after a brain injury are very common and healthcare in this field needs developing.” He asserts that both muscular and perceptual vision disorders can be effectively treated with the right interventions.
Pansell’s background in optometry began early. Born in 1972 in Eksjö, Sweden, he started working in his parents’ optician practice at age 13. After earning his degree in optometry from Karolinska Institutet in 1999, he initially planned to take over the family business. Instead, he chose to pursue postgraduate studies and is currently a research group leader at St Erik Eye Hospital’s Marianne Bernadotte Centre, where he holds a clinical position in the neuro-ophthalmology department.
Pansell’s commitment to advancing the understanding and treatment of visual disorders following brain injuries positions him at the forefront of a critical area of healthcare. His contributions may lead to significant improvements in the quality of life for many individuals affected by these complex conditions.
