1. The primary function of the cornea is
A. Protection against UV light
B. Refraction of light onto the retina
C. Nutrient absorption
D. Pigment formation
The cornea provides most of the eye’s refractive power, focusing
light onto the retina.
2. The fovea centralis is responsible for
A. Peripheral vision
B. High visual acuity
C. Night vision
D. Color blindness
The fovea contains densely packed cones for sharp, detailed vision.
3. Intraocular pressure is primarily maintained by
A. Vitreous humor production
B. Aqueous humor dynamics
C. Corneal thickness
D. Lens curvature
, Aqueous humor inflow and outflow maintain intraocular pressure
balance.
4. A patient with presbyopia typically needs
A. Reading glasses
B. Bifocals for distance
C. Cataract surgery
D. Corneal reshaping
Presbyopia results from reduced lens accommodation due to
aging.
5. The Snellen chart measures
A. Color vision
B. Depth perception
C. Visual acuity
D. Eye pressure
The Snellen chart determines how clearly a person can see at
specific distances.
6. Myopia is corrected with
A. Concave (diverging) lenses
B. Convex (converging) lenses
C. Cylindrical lenses
D. Bifocal lenses
Concave lenses spread light rays, allowing myopic eyes to focus
properly.
7. The optic disc corresponds to the
A. Macula
B. Blind spot
C. Fovea
, D. Aqueous outlet
The optic disc lacks photoreceptors, creating a natural blind spot.
8. A patient diagnosed with glaucoma has damage to
A. The corneal stroma
B. The lens capsule
C. The optic nerve
D. The retina pigment epithelium
Glaucoma causes progressive optic nerve damage due to high
intraocular pressure.
9. The Ishihara test evaluates
A. Visual field defects
B. Color vision deficiency
C. Accommodation
D. Binocularity
The Ishihara test detects red-green color blindness through
number plates.
10. Cycloplegic refraction is performed to
A. Measure corneal thickness
B. Test intraocular pressure
C. Paralyze accommodation for accurate refraction
D. Assess tear film
Cycloplegia temporarily halts accommodation to measure true
refractive error.
11. Keratoconus affects the
A. Retina
B. Lens
C. Cornea
