Phlyctenule reaction on the cornea (Video)

This slitlamp video shows a phylectenule bump on the surface of the cornea. This inflammatory nodule is caused by a delayed hypersensitivity reaction to staph antigens in a case of bad blepharitis. This case was successfully treated with good lid hygeine, erythromycin ointment, and a mild steroid.

  1. Is there any sound to go along with these videos? My son has staph marginal keratitis and it would be really helpful to hear an explanation.

    Thanks in advance,

    Anastasia
