Iatrogenic ocular silver nitrate burn.

Two cases of silver nitrate burn occurred after treatment of superior limbic keratoconjunctivitis with a solid silver nitrate applicator. After medical treatment and several months of observation, visual acuity eventually returned to acceptable levels with minimal corneal scarring. These cases emphasize the fact that silver nitrate should be used very cautiously around the eye and only in a fresh 0.5-1% solution. The use of solid silver nitrate should be prohibited around the eye.
