What is the main symptom experienced by patients with Thygeson's Superficial Punctate Keratopathy?

• A. Eye pain
• B. Foreign body sensation
• C. Photophobia
• D. Redness

Answer: (B)

Thygeson's superficial punctate keratopathy mainly causes irritation felt as a foreign body sensation because the disease involves superficial corneal epithelial defects. The tiny surface erosions disrupt the epithelial nerve endings, producing that gritty, something-in-the-eye feeling that patients report most often. Pain is usually mild since the issue is confined to the surface rather than the deeper cornea or stroma. Redness can occur but tends to be mild, and photophobia may accompany flares but is not the defining complaint. The hallmark is the persistent irritation from surface epithelial changes, which is why foreign body sensation is the best answer.
