If a RAPD is observed (also known as a Marcus Gunn pupil), it indicates asymmetrical (bilateral symmetrical damage does not produce RAPD) retinal, optic nerve or optic tract damage, although post-chiasmic lesions rarely produce a clinically detectable RAPD.
Generally, central visual field programmes are considered adequate to reveal the majority of visual field defects that one is likely to encounter arising from intracranial lesions, including those at the optic chiasm or optic tract.
Posterior involvement of the optic tracts and radiation and lateral geniculate body is less commonly seen.
