1. What is the first-line treatment for bacterial conjunctivitis?
A. Oral antibiotics
B. Antiviral medications
C. Topical antibiotics
D. Steroid eye drops
Answer: C) Topical antibiotics
Rationale: Bacterial conjunctivitis is typically treated with topical
antibiotics to eliminate the infection.
2. Which layer of the cornea contributes most significantly to its
transparency?
A. Epithelium
B. Stroma
C. Endothelium
D. Descemet's Membrane
Answer: C) Endothelium
Rationale: The endothelium maintains corneal dehydration, which is
crucial for its transparency.
3. What is the primary function of aqueous humor?
,A. Provide nutrients to the cornea and lens
B. Maintain intraocular pressure
C. Refract light entering the eye
D. Both A and B
Answer: D) Both A and B
Rationale: Aqueous humor supplies nutrients to avascular structures
like the lens and cornea and helps maintain intraocular pressure.
4. What is the most common cause of childhood blindness worldwide?

A. Anterior Uveitis
B. Bacterial Keratitis
C. Endophthalmitis
D. Glaucoma
, Answer: B) Bacterial Keratitis
Rationale: A hypopyon (pus in the anterior chamber) is a classic finding
in severe bacterial keratitis.
6. What is the gold standard for diagnosing open-angle glaucoma?
A. Visual Field Testing
B. Tonometry
C. Optical Coherence Tomography (OCT)
D. Gonioscopy
Answer: D) Gonioscopy
Rationale: Gonioscopy is the gold standard for evaluating the angle of
the anterior chamber, essential in diagnosing glaucoma types.

vision. What is the most likely diagnosis?
A. Retinitis Pigmentosa
B. Glaucoma
C. Optic Neuritis
