Welcome to ExFix – Looking forward!

If you are unable to see straight ahead you have to look to the side of the things you want to see. When the image falls outside the area of the retina called the macula, it will have less clarity. This is due to the smaller number of cones in the peripheral regions of the retina as compared to the central area. Despite this vision is better in the periphery than in the area of central loss (the scotoma), especially if the object can be magnified sufficiently. An area on the retina which provides relatively good vision is called the “Best Retinal Area" (BRA). It is important to keep looking in that direction the whole time (and maintain good, steady fixation). The next possible step is to have variety of retinal areas for different tasks, e.g. for reading or identifying faces.

About Eccentric Fixation

When eccentric viewing is working well a person has chosen and uses an area outside the central visual field loss. Training can help to stabilize fixation with this new area, thus enabling or facilitating daily visual tasks like reading or directing their gaze at objects of interest. People thus are able to regain some independence and usually report positive effects on their quality of life.

Eccentric viewing training and a more stable eccentric fixation are also associated with an enhanced processing of visual information in the brain. During eccentric viewing training, it could be shown that an improvement in fixation stability was positively correlated with an increase in brain activation (Rosengarth et al., 2013). This was observable in areas of early visual cortex as well as in higher areas of visual processing that play a role in object or face recognition. Further, in a visual search task a highly stable eccentric fixation was associated with higher performance and also with a task-related increase in activation in visual cortex (Plank et al., 2013).

ABOUT EXFIX
Here we have collected material available within the field of vision-rehabilitation. Eccentric fixation is a good method as a number of researchers have shown that training has a positive effect on those areas in the brain responsible for receiving signals from the areas which have been trained beyond the region of central field loss (scotoma).
