INADVERTENT USE OF CHLORHEXIDINE INSTEAD OF BALANCED SALT SOLUTION FOR INTRAOCULAR IRRIGATION

In three consecutive cataract operations, chlorhexidine was inadverten tly used as an intraocular irrigating solution as a result of inattent iveness of an assistant. In two of the three patients, corneal endothe lium damage was so severe that penetrating keratoplasty had to be perf ormed. Further effects included pronounced iris atrophy, anterior cham ber applanation, and a retrocorneal membrane. In one case, an increase in intraocular pressure developed. No effects were observed in the re tina or optic nerve. Inadvertently using chlorhexidine for intraocular irrigation has far-reaching consequences for the affected eye and is recognizable by streak formation in the anterior chamber when intraocu lar infusion is initiated. To avoid such mistakes, the markings of the two bottles should be of different colors.
