AMERICAN BOARD OF OPTOMETRY EXAM PRACTICE QUESTIONS
WITH ACCURATE SOLUTIONS
1) Which retinal finding is pathognomonic for diabetic macular edema?
A) Microaneurysms
B) Flame hemorrhages
C) Hard exudates in the macula
D) Cotton wool spots -- Correct Answer ✔✔ C. Hard exudates in the
macula
Rationale: Hard exudates in the macula indicate lipid leakage from damaged
capillaries in diabetic macular edema.
2) Which is the main risk factor for developing age-related macular degeneration?
A) Diabetes mellitus
B) Hypertension
C) Age >60 years
D) Myopia -- Correct Answer ✔✔ C. Age >60 years
, Rationale: Aging is the primary risk factor for AMD, particularly in individuals
over 60.
3) Which eyelid tumor is most commonly malignant?
A) Chalazion
B) Papilloma
C) Basal cell carcinoma
D) Seborrheic keratosis -- Correct Answer ✔✔ C. Basal cell carcinoma
Rationale: Basal cell carcinoma is the most common malignant eyelid tumor, often
on the lower lid.
4) Which diagnostic test is used to differentiate dry from wet ARMD?
A) Visual field testing
B) OCT
C) Fluorescein angiography
D) Tonometry -- Correct Answer ✔✔ C. Fluorescein angiography
Rationale: Fluorescein angiography identifies choroidal neovascularization
characteristic of wet AMD.
5) What is the first-line treatment for viral conjunctivitis?
A) Supportive care (lubricants, hygiene)
B) Topical antibiotics
C) Topical steroids
D) Antiviral drops -- Correct Answer ✔✔ A. Supportive care
(lubricants, hygiene)
, Rationale: Viral conjunctivitis is self-limiting; management focuses on symptom
relief and preventing spread.
6) Which condition is most associated with corneal arcus in younger patients?
A) Aging
B) Hyperlipidemia
C) Diabetes
D) Hypertension -- Correct Answer ✔✔ B. Hyperlipidemia
Rationale: Corneal arcus in patients <50 years may indicate hyperlipidemia and
increased cardiovascular risk.
7) Which layer of the tear film contains antimicrobial proteins such as lysozyme?
A) Lipid layer
B) Aqueous layer
C) Mucin layer
D) Goblet cells -- Correct Answer ✔✔ B. Aqueous layer
Rationale: The aqueous layer contains proteins like lysozyme and lactoferrin that
help protect against infection.
8) Which eye disease is associated with drusen accumulation?
A) Diabetic retinopathy
B) Glaucoma
C) Age-related macular degeneration
D) Retinitis pigmentosa -- Correct Answer ✔✔ C. Age-related macular
degeneration
, Rationale: Drusen are extracellular deposits in Bruch’s membrane, commonly
seen in AMD.
9) Which retinal pathology is most likely to cause floaters and flashes?
A) Macular degeneration
B) CRAO
C) Retinal detachment
D) Glaucoma -- Correct Answer ✔✔ C. Retinal detachment
Rationale: Retinal tears or detachment lead to vitreous traction, causing
photopsia and floaters.
10) Which ocular structure produces aqueous humor?
A) Lens
B) Trabecular meshwork
C) Ciliary body
D) Iris -- Correct Answer ✔✔ C. Ciliary body
Rationale: The ciliary body’s epithelium produces aqueous humor, which flows
through the anterior chamber.
11) Which systemic condition is strongly associated with retinal vein occlusion?
A) Diabetes mellitus
B) Hypertension
C) Hyperthyroidism
D) Asthma -- Correct Answer ✔✔ B. Hypertension
