Preliminary CDC laboratory testing identified Bipolaris hawaiiensis, a rare environmental mold infrequently described as a human pathogen, in ocular specimens from these case-patients.
All available isolates from the 11 confirmed cases that occurred following intravitreal injection of triamcinolone-containing products have been identified as the mold Bipolaris hawaiiensis. Both Fusarium and Bipolaris are ubiquitous molds present in air, soil, and water.
(9) In the 40 cases described by Dubey et al, (4) aspergilloma was the most frequent organism found (25, 63%), followed by mucormycosis (7, 18%), cryptococcoma (3), Cladosporium (3), Bipolaris hawaiiensis (1), and Candida species (1).
