Résumé

RESUMO Os autores relatam dois casos de ceratite fúngica, que apresentam em comum no exame histopatológico: a ausência de epitélio, sem ulceração e a integridade da camada de Bowman com a presença de formas fúngicas no seu interior. São sugeridos prováveis mecanismos de recidiva das ceratites fúngicas, ressaltando uma possível "via externa não usual", por meio da penetração do fungo através da camada de Bowman íntegra. A existência desta infecção oportunista não está relatada na literatura oftalmológica e são necessárias mais evidências para que seja considerada como tal.


ABSTRACT The authors describe two cases of fungal keratitis which, upon histopathological examination, are found to have in common the absence of epithelium, without ulceration and the lack of integrity of the Bowman's layer with the presence of fungal forms in their interior. Through them the authors suggest probable mechanisms of recurrence of fungal keratitis, highlighting the possible existence of an "unusual external route" that would occur by the fungus penetration through the full Bowman layer. Although these findings appear not yet reported or recovered in the ophthalmic literature, the authors suggest that they could be possible opportunistic infection signals which, however, require more evidence to be considered as such.
