Q1. Where is aqueous humor produced?
- Lacrimal gland
- Choroid only
- Ciliary processes
- Optic disc
Q2. What structure connects the ciliary body to the lens?
- Short ciliary nerves
- Optic nerve fibers
- Extraocular tendons
- Zonular fibers
Q3. What happens to the lens during accommodation for near vision?
- It becomes flatter
- It becomes opaque
- It becomes more convex
- It moves into the anterior chamber
Q4. Which retinal region provides the highest visual acuity?

- Ciliary process
- Optic disc
Q5. Why is the optic disc called the physiological blind spot?
- It contains only rods
- It is covered by the iris
- It is completely avascular
- It contains no photoreceptors
Q6. Which artery is the principal arterial supply to the inner retina?
- Central retinal artery
- Facial artery
- Middle meningeal artery
- Superficial temporal artery
Q7. Which vessels are especially important for supplying the outer retina and photoreceptors?
- Central retinal vein
- Lacrimal vessels only
- Angular artery only
- Choroidal circulation
Q8. Through which route does aqueous humor normally leave the anterior chamber?
- Trabecular meshwork into the scleral venous sinus
- Through the optic disc into the optic nerve
- Through the lacrimal puncta
- Through the pupil into the vitreous body
Q9. Which nerve provides the afferent limb of the corneal reflex?
- Optic nerve, CN II
- Oculomotor nerve, CN III
- Facial nerve, CN VII
- Ophthalmic division of CN V
Q10. Which autonomic pathway constricts the pupil?
- Sensory fibers through CN II
- Sympathetic fibers from the superior cervical ganglion
- Parasympathetic fibers through the ciliary ganglion
- Somatic fibers through CN VI
