Extended Data Fig. 4: Changes to functional vision evaluated with visual navigation challenge (VNC) obstacle course.

a, b, Best mobility levels passed in the treated eye (up triangle) and in the untreated eye (down triangle). There is a rapid improvement with treatment peaking at month 1 and sustained through month 15. The raw score representing number of course levels that was navigable (a) and change of navigable levels from baseline performance (b) are shown for both treated and untreated eyes. Symbols are individual data points. c, The interocular difference of the number of course levels that was navigable. Treated eye that was initially the worse eye becomes the better eye. Symbols are the differences between individual data points from each eye.
