What is the embryological origin of the retina?

Explanation:
The retina comes from neural ectoderm, reflecting its origin as part of the central nervous system. Early in development, the forebrain forms the optic vesicles, which invaginate to become the optic cups. The inner layer of the optic cup differentiates into the neural retina, while the outer layer becomes the retinal pigment epithelium. This contrasts with other ocular tissues: neural crest cells contribute to structures like the corneal stroma and parts of the uveal tract, and mesoderm forms sclera and extraocular muscles.
