Abstract :
Aim: To report an unusual case of vitiligo iridis.
Case Report: We examined a 55 year old woman attending our OPD with diminution of vision. Upon
examination, we found multiple greyish-white circular spots on the anterior surface of the iris with punched
out margins in the left eye. She also had a history of small pox in the past.
Vitiligo iridis is a rare sequelae of Variola (small pox) infection. There are a few causes like surgical trauma,
chronic iridocyclitis, chronic glaucoma, etc., which can cause iris atrophic patches but Variola infection is
the most common cause of vitiligo iridis presenting with focal areas of iris atrophy.
Conclusion: Even though the small pox has been eradicated, the patients of the elderly age group might
present with the incidental findings of vitiligo iridis, which may or may not be associated with elevated
intraocular pressure. Vitiligo iridis can present as a complication of a number of conditions. Hence, finding
out the probable cause becomes of great importance to help prevent misdiagnosis as an unrelated cause of
focal or multifocal iris atrophy. This can in turn help further management of the underlying cause.
