Embryology of eye mnemonic

Hello friends!

Here's is the simplest way to remember embryology of eye.

*Out of all layers (ecto,meso, endo), the endoderm doesn't contribute to the embryology of eye.

* Mesoderm forms - extraocular muscles

* Rest of the structures are derived from ectoderm.

* Surface ectoderm forms the structures which are visible to us from outside like Corneal epithelium

Conjunctival epithelium

 Lacrimal gland

 Lens ( important)

*Neuroectoderm forms neural structures like

Retina

Ciliary body ( not muscles)

Iris - both sphincter and dilator pupillae

Optic nerve

* Neural crest derivatives are 

Meninges of optic nerve

Schwann cells

Ciliary ganglion

Ciliary muscles 

For the remaining derivatives, watch the following picture.

Thank you.
