Understanding Relative Afferent Pupillary Defects

Exploration of the physiology and pathways involved in relative afferent pupillary defects, detailing how light signals are processed in the visual system through the optic nerve and related nuclei. Emphasis on the bilateral projection of signals and the implications of asymmetry in optic tract fibers for diagnosing neurological issues. Discussions include examples, causes, and distinguishing features in diagnosing retinal or optic nerve problems, particularly in cases of monocular vision loss related to the macula.
