1. Ankita sharma

2. OVERVIEW OF EYE ANATOMY

3. ANATOMY OF EYE

4. Black looking aperture (black due to the absorbing
pigment of the retina )
Allows the light to enter to the eye

5. SCLERA

6.  COLORED, RING MEMBRANE
 GIVES COLOUR TO THE EYE
 CONTROLS THE SIZE OF THE PUPIL DEPENDING ON THE AMOUNT
OF LIGHT ENTERING INTO THE EYE

7. EXTERNAL LAYER – SCLERA AND CORNEA
INTERMEDIATE LAYER- ANTERIOR (IRIS AND CILIARY BODY )
AND POSTERIOR (CHOROID )
INTERNAL LAYER – RETINA ( THE SENSORY PART )

8.  At the front of eyeball , sclera continues into
cornea .
 Dome-shaped transparent part of eyeball
 Rays of light from outside world passes through
cornea before passing through the lens

9. Middle layer of the eyeball.
 located between sclera and retina .
Provides nutrients and oxygen to the outer surface of the
retina.

10. The space between cornea and lens
Filled with aqueous humor

11.  Largest chamber of the eye
 Between lens and retina
 Filled with the amorphous somewhat gelatinous
material of the vitreous body

13.  Second of several pairs of cranial nerves
 The job of this nerve is to transfer visual information from
retina to visual centre of brain via electrical impulse
The optic nerve made up of ganglion cells or nerve cell
