PURPOSE: To describe a rare case of Rhizopus angle abscess progressing to scleritis and endophthalmitis after routine cataract surgery with Kahook Dual Blade (KDB) goniotomy in an immunocompetent patient.
OBSERVATION: A 79-year-old male developed hyphema and anterior chamber fibrin three days after uncomplicated phacoemulsification with KDB. Despite intravitreal vancomycin and ceftazidime, inflammation worsened, and by postoperative day nine vision was count fingers with intraocular pressure of 29 mmHg. Slit-lamp exam showed an inferonasal corneal infiltrate with a purulent angle abscess at the goniotomy site and dense vitritis. Intravitreal and oral voriconazole were started for presumed fungal infection. Standard cultures and PCR were negative, but metagenomic RNA deep sequencing of aqueous fluid detected Rhizopus stolonifer. After two months of systemic and intravitreal voriconazole, the infection resolved and visual acuity improved to 20/70, leaving localized limbal thinning.
CONCLUSION AND IMPORTANCE: This case illustrates that Rhizopus angle abscess can occur in an immunocompetent host following anterior segment surgery and may masquerade as bacterial endophthalmitis. Early suspicion of fungal infection and use of metagenomic deep sequencing were critical for diagnosis and successful treatment, emphasizing the need to consider invasive fungal pathogens and advanced molecular diagnostics in culture-negative postoperative ocular infections.
