Embryology of the human Eye

The human eye anatomically is considered as an extension of the brain.the central nervous develop from the neural tube.A thickening appears on either sides of the neural tube in its anterior part known as OPTIC PLATE.The optic plate grows as the Foetus(baby) grows towards the surface to form the OPTIC VESICLE.the two eyes develop from these two optic vesicles.the neural ectoderm and mesoderm come together to form the optic vesicles.
As the foetus grows the optic visicles invaginates from in front and below to form the OPTIC CUP. there is a line of invagination that remains open  for sometime known as the embryonic fissure.the hyloid artery enters through the fissure to provide nutrients to the developing structures.later atrophies found dissapears.
The inner layer of the retina(main) is formed by the inner layer of the optic cup whiles the outer layer develops into the pigmented epithelium.the neural ectoderm is responsible for the secretion of the jelly-like fluid called the VITREOU…
