Ophthalmologic Examination in Candidemia

The American College of Physicians and the Infectious Diseases Society of America recommend that all patients with candidemia undergo dilated retinal examination because Candida can spread hematogenously to the eye, causing endophthalmitis that threatens permanent vision loss, and this complication is often asymptomatic until irreversible damage occurs 1, 2
Candida species reach the posterior chamber of the eye via hematogenous spread during candidemia, establishing endogenous infection that manifests as chorioretinitis or progresses to vitritis and endophthalmitis, with all Candida species causing candidemia documented to cause this ocular complication 1, 2, 3

Screening and Diagnosis

Patients who are examined only after developing ocular symptoms have significantly worse visual outcomes compared to those diagnosed through screening examination, emphasizing the importance of early detection 2, 3
The Infectious Diseases Society of America suggests performing dilated retinal examination within the first week of antifungal therapy for nonneutropenic patients, and delaying examination until neutrophil recovery for neutropenic patients to allow adequate visualization 1, 4, 5

The extent of ocular involvement fundamentally determines treatment strategy, with systemic antifungal therapy alone sufficient for chorioretinitis without vitritis, but requiring additional interventions such as intravitreal injection of amphotericin B deoxycholate or voriconazole for macular involvement or vitritis/endophthalmitis 1, 3, 4, 5
The IDSA explicitly acknowledges that the recommendation for universal ophthalmologic examination is not based on randomized controlled trials, but rather on clinical judgment that the consequence of missing Candida endophthalmitis is too severe to accept 2, 3

The Infectious Diseases Society of America advises against waiting for visual symptoms before performing examination, as symptomatic presentation correlates with worse visual outcomes, and against assuming systemic antifungal therapy alone is adequate without documenting the absence of ocular involvement 2, 3, 1
