01. The sensory nerve supply of the eye is by the

1. a. optic nerve
2. b. third cranial nerve
3. c. fifth cranial nerve✓
4. d. seventh cranial nerve

• Ophthalmic nerve (part of the trigeminal nerve, CN V): This nerve has three branches: The lacrimal nerve runs to the lacrimal gland and gives off branches to the conjunctiva and skin of the superior eyelid.
• The frontal nerve enters through the superior orbital fissure and provides sensory innervation to the superior eyelid, scalp, and forehead. The nasociliary nerve is the sensory nerve to the eyeball. It also has branches that serve the orbit and other parts of the face. One of its branches, the infratrochlear nerve, supplies the eyelids, conjunctiva, and lacrimal sac.

ahead. The extent of the normal visual field is limited in an individual by anatomical

features such as the brow superiorly, the nose nasally and the cheek inferiorly. It is seen

that the field for a white target extends 60° upwards, rather more than 90° outwards, 70°

downwards and 60° inwards. The extent varies with illumination, size of the test-object,

contrast of the test-object vis-à-vis the background, and the state of adaptation of the

eye.

Ophthalmic nerve (part of the trigeminal nerve, CN V): This nerve has three branches:
