Retina
Covers the posterior five sixth of the eyeball
Sclera
Completely avascular
Cornea
Covers the one sixth of the eye
Cornea
White of the eye
Sclera
Serves as attachment of extrinsic and intrinsic muscles
Sclera
Pierced by nerves and vessels even the optic nerve posteriorly
Sclera
Which layer is alternatively called Uvea?
Vascular layer
Thin, highly vascular and pigmented
Choroid
Thin contractile diaphragm
Iris
Situated between iris and choroid
Ciliary body
Firmly attached to retina internally and loosely attached to the sclera externally
Choroid
Triangular shaped structure
Ciliary body
Name the layers that form the retina
Pigmented and neural layer
Formation of the non visual part of retina
Continuation of pigmented layer anteriorly
Formation of optic part of retina
Formed by pigmented layer and neural layer
Function of pigmented layer
Absorbs light
Function of neural layer
Light receptive/ detector
