Noninfectious Endophthalmitis Following Intraoperative Indocyanine Green

Abstract

BACKGROUND AND OBJECTIVE: The purpose of this article is to describe a cluster of four cases of severe postoperative inflammation in eyes that received intraoperative indocyanine green (ICG) from the same lot. PATIENTS AND METHODS: This was a retrospective chart review of patients from a single-center, retina-only group practice. The ICG lot associated with the inflammatory events was identified and analyzed with high-performance liquid chromatography with UV spectroscopy. RESULTS: Four patients presented on postoperative day 1 with severe inflammation. The first patient was treated with aqueous biopsy and injection of intravitreal antibiotics, followed by topical steroid and antibiotic drops. The subsequent three patients were treated with topical steroid and antibiotic drops. All patients had resolution of inflammation by postoperative day 14 (range 10 to 14 days). High-performance liquid chromatography with UV spectroscopy failed to identify a contaminant. CONCLUSIONS: The use of intravitreal ICG dye as a surgical adjuvant may uncommonly be associated with severe postoperative inflammation. This inflammation may resolve within weeks after topical corticosteroid and antibiotic treatment. [ Ophthalmic Surg Lasers Imaging Retina . 2022;53:148–151.]
