Explanation of the different structures of the eye
The choroid is the vascular layer at the back of the eye behind the retina.
The cornea is a transparent structure situated at the front of the eye. It is also commonly known as the “clear window of the eye”.
Sclera and conjunctiva
The sclera is the outermost layer of the eye and offers protection to the internal structures.
The lens is a clear and flexible structure located behind the iris that enables us to see objects in sharp detail.
Iris and Pupil
The iris is the structure that gives the eye colour. The pupil is the black hole in the middle of the iris.
The optic nerve connects our eye and brain together to form a visual image (what we see).
The retina is a layer at the back of the eye that detects light. It consists of different types of specialised cells to help generate a visual image (what is seen).
The trabecular meshwork is a specialised structure located between the iris and the base of the cornea. It regulates eye pressure by draining the aqueous humour.
The vitreous humour is a colourless, transparent jelly-like substance located between the lens and the retina.
