SIGNIFICANCE: Fungal endogenous endophthalmitis is an uncommon and potentially blinding infection. Aspergillus is a causative organism in immunocompromized although is virulent enough to afflict immunocompetents. Their propensity to affect macula usually results in a dismal prognosis; thus, improving visual outcome has always been challenging to clinicians. A. nidulans has only rarely been implicated in exogenous endophthalmitis. PURPOSE: To report the first case of A. nidulans endogenous endophthalmitis. CASE REPORT: An asthmatic 42-year-old female presented with sudden unilateral vision loss due to a submacular abscess that progressively worsened in a matter of days. Vitreous PCR analysis after an urgent vitrectomy was positive for A. nidulans with no active systemic foci found. Oral and intravitreal Voriconazole was prescribed but multiple reactivations led to three vitrectomies in total alongside with subretinal Voriconazole, abscess aspiration, and endolaser. There was complete resolution of the infection and, although visual acuity was poor due to macular scar, enucleation was avoided. CONCLUSION: Although uncommon, we must consider Aspergillus as the causative organism in apparently immunocompetent patients with history of recent systemic corticosteroids treatment, especially if they suffer a broncopulmonary disorder. Aspergillus is an aggressive organism so a high index of suspicion along with early diagnosis and prompt treatment is the key for better outcomes. We highlight A. nidulans as the causative agent as there are no other reported cases.
