The anatomy of the retina is a fundamental field in ophthalmology, revealing complex structures and essential interactions for vision. The envelope of the eye, including the uvea (composed of the choroid, iris, and ciliary bodies), protects and supports the retina. The latter is divided into two main layers: the outer retina and the inner retina. The formation of the primitive optic cup is crucial, as it establishes a juxtacrine connection with the surface epiblast, leading to a thickening of the latter and the creation of the outer optic placode.

The phenomenon of retinal detachment is a significant clinical complication, often encountered in medical practice. This detachment occurs when the developing retina forms a primitive depression, thus separating the inner and outer layers. It is interesting to note that the retina is actually a tissue derived from the brain, more precisely from ventricular tissue, highlighting the importance of embryology in understanding ocular pathologies. A thorough knowledge of these structures and their interactions is essential for the diagnosis and treatment of retinal affections.
