CONCLUSION: Mucormycosis is a life-threatening, opportunistic infection, and patients with moderate to severe COVID-19 are more susceptible to it. Uncontrolled diabetes mellitus and use of corticosteroids increase the risk of invasive fungal infection with mucormycosis which can develop during the course of the illness or as a sequelae. High index of suspicion, early diagnosis, and appropriate management can improve survival.
CONCLUSIONS: Molecular methods may be useful for the identification of filamentous fungal keratitis on scraping samples thus shortening the time of diagnosis. Systemic therapy by isavuconazole could be useful to treat the filamentous fungal keratitis, reducing the possible adverse effects due to the use of voriconazole by systemic administration.
