Which ocular finding is NOT associated with syphilis?

• A. Interstitial keratitis
• B. Argyll-Robertson pupil
• C. Herbert's pits
• D. Macular exudative star

Answer: (C)

The main idea is recognizing which eye findings are classically linked to syphilis and which are not. Ocular syphilis can show up as anterior segment changes like interstitial keratitis, and as pupil and retinal findings such as an Argyll-Robertson pupil and certain retinal signs (retinal/posterior uveitis patterns can include exudates around the macula in some cases).

Herbert's pits are not a typical or classic manifestation described for syphilitic eye disease. They are not used as a diagnostic clue for syphilis and do not represent a characteristic corneal change of syphilis. In contrast, interstitial keratitis and Argyll-Robertson pupil are well-known associations with syphilis, and macular exudative changes can appear in syphilitic retinal involvement. So the corneal finding that does not fit the syphilis pattern is Herbert's pits.
