The efficient organization of the human afferent visual system meets enormous computational challenges. Once visual information is received by the eye, the signal is relayed by the retina, optic nerve, chiasm, tracts, lateral geniculate nucleus, and optic radiations to the striate cortex and extrastriate association cortices for final visual processing. At each stage, the functional organization of these circuits is derived from their anatomical and structural relationships. In the retina, photoreceptors convert photons of light to an electrochemical signal that is relayed to retinal ganglion cells. Ganglion cell axons course through the optic nerve, and their partial decussation in the chiasm brings together corresponding inputs from each eye. Some inputs follow pathways to mediate pupil light reflexes and circadian rhythms. However, the majority of inputs arrive at the lateral geniculate nucleus, which relays visual information via second-order neurons that course through the optic radiations to arrive in striate cortex. Feedback mechanisms from higher cortical areas shape the neuronal responses in early visual areas, supporting coherent visual perception. Detailed knowledge of the anatomy of the afferent visual system, in combination with skilled examination, allows precise localization of neuropathological processes and guides effective diagnosis and management of neuro-ophthalmic disorders.

K. Khurana, Indu KhuranaCBS Publishers & Distributors, Nov 30, 2021 - Anatomy - 514 pages 1 ReviewReviews aren't verified, but Google checks for and removes fake content when it's identifiedThis is an updated and thoroughly revised edition of a well-established and a unique integrated book on anatomy and physiology of the eye. Though written primarily for postgraduate degree and diploma students in ophthalmology it is hoped that this book will also prove useful for the postgraduates from the disciplines of anatomy and physiology.The subject matter has been arranged over fourteen chapters and provides an opportunity for a continuous reading of interrelated text on anatomy and physiology of the eye. A brief list of the contents given in the beginning of each chapter provides a clear layout of the text. The text has been profusely illustrated with high quality computer drawn colour diagrams.
