Retina Pdf Retina Visual System This paper focuses on the anatomical and functional properties of the visual system, providing a comprehensive overview of how the brain processes visual information. Detailed knowledge of the anatomy of the visual system, in combination with skilled examination, allows precise localization of neuropathological processes. moreover, these principles guide effective diagnosis and management of neuro ophthalmic disorders.
Complete Visual System Pdf Vision is used to guide locomo tion, coordinate hand movements, recognize objects and scenes, direct attention, and entrain circadian rhythms. to accomplish these many functions, the nervous system includes a sophisticated network of visual pathways and structures. The functional optic part of retina lines the fundus to the level of the ora serrata. retina overview. the retina develops from the optic cup of the diencephalon, and the optic nerve is histologically a cns tract. ten histological layers are recognized in the optic part of the retina. light. • the retina transduces photons into patterns of action potentials to send to brain • the output of retina (retinal ganglion cells) has centre surround receptive fields • they act as a bandpass filter, efficiently encoding compressing images to send to brain. Retina containing the photoreceptors. en route to the retina, light successively travels through the cornea, the aqueous humor (the clear and watery liquid within the anterior chamber that regulates the intraocular pressure), the lens, and the vitreous humor (the thick gelatinous substance that accounts for the size and shape of the globe).

Different parts of the globe (e.g., the lens, iris, conjunctiva, sclera, retina, ciliary body, cornea, and optic nerve) have different sensitivities to irradiation. some structures like the optic. The visual system includes the eyes, their accessory structures and the visual pathways that relay information to the visual cortex, where it is decoded to pro duce our view of the world around us. accessory structures of the eye to maintain optimal ocular health and vision, each eyeball has several associated accessory structures (fig 1).

We sought collaborations with ophthalmologists, anatomists, physiologists, physicists, and psychologists, aiming to relate visual psychophysics to the underlying physiology of the primate retina. this review describes our journey and reflections in exploring the visual system.
