Chronic trachoma infection can lead to what corneal outcome?

• A. No vision impact
• B. Reversible corneal scarring
• C. Permanent corneal scarring that can abrade the cornea
• D. Immediate blindness within days

Answer: (C)

Chronic trachoma causes repeated inflammation of the conjunctiva and eyelid scarring, which leads to inward turning of the eyelashes (trichiasis). Those lashes constantly rub against the cornea, causing mechanical injury and chronic epithelial damage. Over time, this ongoing irritation and inflammation drive the formation of scar tissue on the cornea, resulting in permanent corneal scarring that can severely blur vision. Because the damage comes from fibrosis and lasting scar formation, it isn’t reversible with simple treatment, and the vision loss can progress if the condition isn’t addressed. The idea that there’s no vision impact is incorrect, and the belief that scarring would be reversible or that blindness would occur within days doesn’t fit the progressive, scar-driven nature of the outcome.
