A 70-year-old man presents with gradual lower lid inturning causing corneal irritation. On examination the lid turns inward only when he forcibly closes his eye but is normal at rest. This type of entropion is classified as:
- A Senile/involutional entropion with intermittent spasm component ✓
- B Cicatricial entropion due to conjunctival scarring
- C Acute spastic entropion due to ocular surface irritation
- D Congenital entropion due to epiblepharal hypertrophy
Correct answer: A. Senile/involutional entropion with intermittent spasm component
Explanation
Involutional (senile) entropion is the most common form in elderly patients and results from horizontal lid laxity, disinsertion of the lower lid retractors, and overriding of the preseptal orbicularis. It is often intermittent, triggered by forceful lid closure or eye rubbing. Cicatricial entropion shows a fibrotic posterior lamella. Acute spastic entropion follows ocular surface inflammation. Congenital entropion is rare and presents at birth.
