An Unusual Case Of Ruptured Post-Traumatic Iris Implantation Cyst With Co-Existent Anterior Chamber Cilia

Abstract

A 13-year old boy reported with dimness of vision and whitish material inside the right eye since two weeks. There was history of injury with metallic wire in the same eye one and half years ago for which he received symptomatic treatment. He remained asymptomatic apart from mild redness in that eye occasionally. Visual acuity was 6/12 and 6/6 in the right and left eye respectively. A linear corneal scar was noted at the supero-temporal quadrant. Anterior chamber showed presence of whitish fluffy material, part of which was attached to the peripheral iris at 10-11 o’clock. A hair like foreign body was found at the bottom of the anterior chamber. The entire material was removed surgically along with the foreign body. The whitish material revealed small multiple hair like structures under the microscope. Histopathological examination showed eosinophilic acellular material with squam, suggestive of implantation dermoid. The foreign body was subsequently proven to be human hair after forensic evaluation. It was diagnosed as a case of ruptured iris implantation cyst with anterior chamber cilia.
