Q
Where does the eye develop from?
A
Neural tube
2
Q
What is the first part of the developing eye?
A
Optic vesicles
3
Q
What happens when the optic vesicles reach the surface ectoderm?
A
The cells of the surface ectoderm thicken and form the lens placode
4
Q
What is formed when the lens placode starts to push inward (invaginate)?
A
Optic cup
5
Q
How many layers does the optic cup have?
A
2
6
Q

A
Fluid enters into space and separates inner 9 layers of retina from outer 10th layer of retina
7

Eyelids, conjunctiva, corneal epithelium
8
Q
What does the mesenchyme form for the eye?
