Answer 1

Choroid layer:

1. The choroid is the vascular layer of the eye.
2. Also referred to as choroid coat or choroidea, it is a thin layer of tissue that is part of the middle layer of the eye wall, found between the sclera and the retina.
3. The choroid is filled with blood vessels, which bring nutrients and oxygen to the outer layers of the retina.

Sclerotic layer:

1. The sclera is the external layer of the wall of the eyeball.
2. It is made up of dense connective tissue.
3. It differentiates into the cornea in the anterior part of the eye.
4. It is mostly made up of collagen and elastic fibres.
5. The sclera is also called the ‘white of the eye’.
