A mathematical description of nerve fiber bundle trajectories and their variability in the human retina

Vision Res. 2009 Aug;49(17):2157-63. doi: 10.1016/j.visres.2009.04.029. Epub 2009 Jun 16.


We developed a mathematical model wherein retinal nerve fiber trajectories can be described and the corresponding inter-subject variability analyzed. The model was based on traced nerve fiber bundle trajectories extracted from 55 fundus photographs of 55 human subjects. The model resembled the typical retinal nerve fiber layer course within 20 degrees eccentricity. Depending on the location of the visual field test point, the standard deviation of the calculated corresponding angular location at the optic nerve head circumference ranged from less than 1 degrees to 18 degrees , with an average of 8.8 degrees .
