Purpose: To report potentially distinguishing characteristics between bacterial endophthalmitis and presumed noninfectious endophthalmitis associated with intravitreal triamcinolone acetonide injection.
Methods: Records of two patients with culture-proven bacterial endophthalmitis and six patients with presumed noninfectious endophthalmitis from intravitreal triamcinolone acetonide injections were analyzed retrospectively.
Results: Two eyes in two patients with culture-proven bacterial endophthalmitis had decreased vision and hypopyon or vitritis, but no pain or conjunctival injection 2 weeks after intravitreal triamcinolone acetonide injection.
