1. Which part of the eye is primarily responsible for focusing
light onto the retina?
A. Cornea
B. Lens
C. Retina
D. Iris
Answer: A. Cornea, B. Lens
Rationale: The cornea provides most of the eye’s refractive
power, while the lens fine-tunes focus for near and far vision.
2. Which tests are commonly used to assess visual acuity?
A. Snellen chart
B. Ishihara plates
C. LogMAR chart
D. Tonometry
Answer: A. Snellen chart, C. LogMAR chart
Rationale: Snellen and LogMAR charts measure clarity of
vision, while Ishihara assesses color vision and tonometry
measures intraocular pressure.
,3. What is the primary function of the lacrimal gland?
A. Produce tears
B. Drain tears
C. Protect against infection
D. Focus light
Answer: A. Produce tears
Rationale: The lacrimal gland secretes tears to lubricate and
protect the ocular surface.
4. Which conditions are considered refractive errors?
A. Myopia
B. Hyperopia
C. Astigmatism
D. Cataract
Answer: A. Myopia, B. Hyperopia, C. Astigmatism
Rationale: Refractive errors result from improper focusing of
light; cataracts involve lens opacity, not refraction.
5. Which instruments are used to examine the anterior
segment of the eye?
A. Slit lamp
B. Fundus camera
C. Ophthalmoscope
D. Tonometer
,Answer: A. Slit lamp, D. Tonometer
Rationale: A slit lamp provides a magnified view of the anterior
segment; tonometry measures pressure but often involves
anterior structures. Fundus cameras focus on the posterior
segment.
6. What are common symptoms of glaucoma?
A. Peripheral vision loss
B. Eye pain
C. Sudden flashes of light
D. Headache
Answer: A. Peripheral vision loss, B. Eye pain, D. Headache
Rationale: Glaucoma can cause peripheral vision loss and
sometimes ocular pain; flashes of light usually indicate retinal
issues.
7. Which diagnostic tests are used for glaucoma evaluation?
A. Tonometry
B. Visual field testing
C. OCT (Optical Coherence Tomography)
D. Refraction test
Answer: A. Tonometry, B. Visual field testing, C. OCT
Rationale: Tonometry, visual field testing, and OCT help detect
glaucoma. Refraction tests measure visual clarity, not
glaucoma.
, 8. Which types of eye drops are commonly used in ophthalmic
exams?
A. Mydriatics
B. Miotics
C. Corticosteroids
D. Antibiotics
Answer: A. Mydriatics, B. Miotics
Rationale: Mydriatics dilate pupils and miotics constrict them
for exams; corticosteroids and antibiotics treat inflammation
and infection, not exam purposes.
9. What are common causes of conjunctivitis?
A. Bacterial infection
B. Viral infection
C. Allergies
D. Glaucoma
Answer: A. Bacterial infection, B. Viral infection, C. Allergies
Rationale: Conjunctivitis is caused by infections or allergens,
not glaucoma.
10. Which tests help diagnose diabetic retinopathy?
A. Fundus photography
B. Fluorescein angiography
C. Visual acuity test
