Q.9 Which eyelid tumor is associated with Muir-Torre syndrome?
Sebaceous gland carcinoma
Basal cell carcinoma
Chalazion
Melanoma
Explanation - Sebaceous gland carcinoma of the eyelid may be associated with Muir-Torre syndrome, a genetic condition involving sebaceous tumors and internal malignancies.
Correct answer is: Sebaceous gland carcinoma
Q.10 Which eyelid disorder is most likely to cause epiphora?
Entropion
Ectropion
Blepharospasm
Chalazion
Explanation - Ectropion causes the lower eyelid to evert, disrupting the tear drainage system, leading to excessive tearing (epiphora).
Correct answer is: Ectropion
Q.11 Which eyelid condition is described as a painless, firm nodule within the eyelid?
Hordeolum
Chalazion
Basal cell carcinoma
Ectropion
Explanation - A chalazion is a chronic, painless, firm nodule resulting from granulomatous inflammation of the meibomian gland.
Correct answer is: Chalazion
Q.12 Which eyelid condition presents with redness, swelling, and tenderness at the eyelid margin?
Hordeolum
Chalazion
Blepharitis
Entropion
Explanation - Hordeolum is an acute infection causing localized redness, tenderness, and swelling at the eyelid margin.
Correct answer is: Hordeolum
Q.13 Which of the following eyelid lesions is most likely to ulcerate and bleed?
Basal cell carcinoma
Chalazion
Hordeolum
Ectropion
Explanation - Basal cell carcinoma can present as a non-healing ulcer with bleeding, usually on the lower eyelid.
Correct answer is: Basal cell carcinoma
Q.14 A 65-year-old patient has an outward turning of the lower eyelid causing dry eyes. The most likely diagnosis is:
Entropion
Ectropion
Ptosis
Blepharitis
Explanation - In elderly patients, age-related laxity often leads to ectropion, especially of the lower eyelid, causing exposure keratitis and dry eyes.
Correct answer is: Ectropion
Q.15 Which eyelid condition is most commonly associated with long-term contact lens wear?
Blepharitis
Chalazion
Entropion
Basal cell carcinoma
Explanation - Chronic blepharitis can be exacerbated by contact lens wear due to increased bacterial colonization and irritation.
Correct answer is: Blepharitis
Q.16 Which eyelid disorder is characterized by involuntary, forceful closure of the eyelids?
Blepharospasm
Ptosis
Entropion
Hordeolum
Explanation - Blepharospasm is a type of focal dystonia causing involuntary, forceful closure of the eyelids.
Correct answer is: Blepharospasm
Q.17 Which eyelid condition is most commonly caused by chronic staphylococcal infection and seborrheic dermatitis?
Blepharitis
Hordeolum
Chalazion
Ectropion
Explanation - Anterior blepharitis is commonly due to Staphylococcus aureus and seborrheic dermatitis, leading to lid margin inflammation.
Correct answer is: Blepharitis
Q.18 Which of the following is a common cause of congenital ptosis?
Trauma
Horner's syndrome
Levator muscle dysgenesis
Myasthenia gravis
Explanation - Congenital ptosis usually results from developmental defects of the levator palpebrae superioris muscle.
Correct answer is: Levator muscle dysgenesis
Q.19 Which eyelid lesion is most likely to appear as a yellowish nodule along the eyelid margin and is associated with hyperlipidemia?
Xanthelasma
Chalazion

Correct answer is: Xanthelasma
Q.20 Which eyelid condition is commonly associated with trichiasis?
Entropion
Ectropion
Blepharitis
Ptosis
Explanation - Entropion causes the eyelashes to rub against the cornea, resulting in trichiasis and irritation.
Correct answer is: Entropion
Q.21 A recurrent, non-healing lesion of the upper eyelid in an elderly patient should raise suspicion for:
Sebaceous gland carcinoma
Hordeolum
Chalazion
