This PDF covers the anatomy of the visual organ, including the eyeball, its three tunics (fibrous, vascular, and nervous), and internal structures such as the cornea, lens, retina, and vitreous body. It explains retinal layers, photoreceptors, and the visual pathway from light detection to signal transmission through the optic nerve.

Accessory structures including eyelids, conjunctiva, lacrimal apparatus, and extraocular muscles are also presented, along with aqueous humour dynamics and clinical conditions such as glaucoma, cataract, and retinal detachment.
