Abstract

OBSERVATIONS Histopathologic review of 5 eyes from a series of 17 treated with intravitreal triamcinolone for retinal vascular disease and diabetes mellitus over 1 year from 1 lot prepared by a compounding pharmacy. Endophthalmitis occurred in 14 of 17 eyes, the first presenting a mild vitritis 5 days following injection. The onset of signs and symptoms of endophthalmitis (eg, decreased vision, anterior chamber, or vitreous cells) in the 5 cases presented here varied from 5 to 174 days. CONCLUSIONS AND RELEVANCE Vitreous biopsy with cytospin and periodic acid-Schiff stain for hyphae was the most sensitivemethod for proving that fungus was present (positive in 3 of 5 of our cases). Five of 5 sample results from the whole series of 14 clinical cases were confirmed as positive for Bipolaris hawaiiensis by genotyping at the Centers for Disease Control and Prevention. Three of the removed eyes received fresh were culture negative; however, all 5 demonstrated organisms with fungal stains. Symptoms of fungal endophthalmitis can be minimal and delayed long beyond the 5 to 7 days expected for acute bacterial endophthalmitis. Also, apparently viable organisms persist in ocular tissues despite prolonged exposure to antifungal agents. This series reminds us that cytological or histological examination of tissue specimens may be necessary to exclude fungal infections that fail to grow in culture.
