Interstitial keratitis

Avoid using the term syphilis in the presence of the patient. Use euphemism such as ' the condition may be caused by 
TPHA or St. Luis disease'.

The cornea has diffused stromal haze and on high manifestation there are ghost (empty) vessels in the deep and mid-stroma.
The cornea may be thin. The condition is usually bilateral.

Look for the following:

  • signs of congenital syphilis such as saddle-nose, deafness and under-developed dentition.
  • there may be cornea graft in the opposite eye.
