text: Case Report Rhino orbital Mucormycosis Related to COVID 19 A Case Series Exploring Risk Factors There has been a surge of rhino orbital mucormycosis cases in India in the wake of the second wave of the COVID 19 pandemic It has been widely suggested that dysglycemia resulting from diabetes which is a common comorbidity in COVID 19 patients and indiscriminate steroid use has resulted in this surge We report a series of 13 cases of rhino orbital mucormycosis in COVID 19 patients admitted to our center between mid April and early June 2021 The cases showed a male preponderance two patients had loss of vision and four of them showed intracranial extension of disease Twelve patients had received steroids and 12 had preexisting or newly diagnosed diabetes both steroid use and diabetes being the most common identified risk factors Considering other possible risk factors immunosuppressed state antiviral or ayurvedic Indian traditional medications and oxygen therapy were not associated with a definite risk of mucormycosis because they were not present uniformly in the patients We propose that COVID 19 itself through molecular mechanisms predisposes to mucormycosis with other factors such as dysglycemia or steroid use increasing the risk
