Study Summary

This trial will test how well different treatments can improve vision and function in people with visual system damage.

Who is the study for?
This trial is for individuals aged 17-75 who have had a stroke or other damage to their visual cortex after age 16, leading to partial vision loss. They must have some intact visual areas in the brain and demonstrate a deficit in visual perception. Participants need an MRI or CT scan showing cortical damage, no history of neurological disorders, and must be able to use eye drops if needed.Check my eligibility
What is being tested?
The study tests two types of visual retraining: one that focuses on the blind field (areas where vision is lost) and another on the sighted field (areas with remaining vision). The goal is to understand how these trainings can improve spatial awareness, perception, and real-world usage of residual vision after brain damage.See study design
What are the potential side effects?
Since this trial involves non-invasive training exercises rather than medication or surgery, side effects are minimal but may include eye strain or fatigue from intensive visual tasks.

Who is eligible to partake in this research trial?

"This trial is enlisting 400 individuals with hemianopsia, aged between 17 and 75. The primary conditions for admission are: exhibiting a deficit in simple or complex visual perception within their field of vision; being capable and responsible according to the Principal Investigator's judgement; having sustained damage to the primary visual cortex after reaching age 17, rendering them blind over part of their sight range; fitting into the Cortically Blind Subject category."
