Support of the laboratory in the diagnosis of fungal ocular infections.

Vanzzini Zago V, Alcantara Castro M, Naranjo Tackman R - Int J Inflam (2012)

Bottom Line: We describe the microbiological diagnosis in palpebral mycose; in keratitis caused by Fusarium, Aspergillus, Candida, and melanized fungi; endophthalmitis; one Histoplasma scleritis and one mucormycosis.Correct diagnosis is important because an early medical treatment gives a better prognosis for visual acuity.In some cases, fungal infections are misdiagnosed and the antifungal treatment is delayed.

ABSTRACT
This is a retrospective, and descriptive study about the support that the laboratory of microbiology aids can provide in the diagnosis of ocular infections in patients whom were attended a tertiary-care hospital in México City in a 10-year-time period. We describe the microbiological diagnosis in palpebral mycose; in keratitis caused by Fusarium, Aspergillus, Candida, and melanized fungi; endophthalmitis; one Histoplasma scleritis and one mucormycosis. Nowadays, ocular fungal infections are more often diagnosed, because there is more clinical suspicion and there are easy laboratory confirmations. Correct diagnosis is important because an early medical treatment gives a better prognosis for visual acuity. In some cases, fungal infections are misdiagnosed and the antifungal treatment is delayed.

Mentions: The smear with Giemsa stain showed intracellular yeast like forms in hystiocytes, and in cultures after 12 days of incubation, a cottony white colony grew in Sabouraud-Emmons media (Figure 17) and in microculture shown Histoplasma conidia (Figure 18), in a second sample taken from the same sclerotic ulcer, the cultures had the same microbiologic results.
