Abstract
Central retinal artery occlusion (CRAO) is a multifactorial disease, where inflammation and hypercoagulability are the major risk factors. It is a rare occurrence in this geographical area in patients diagnosed with sinus mucormycosis infection, which has emerged as one of the most fulminant, opportunistic secondary infection during post-COVID era. We report a case of a bilateral CRAO, in a 66-year-old, post-COVID, diabetic patient. A complete eye examination followed by radiological imaging of brain, orbit, and paranasal sinuses were done. Multidisciplinary approach was contemplated to reach a diagnosis of bilateral rhino-orbital-cerebral mucormycosis (ROCM). Intravenous liposomal amphotericin-B injection was started as a part of systemic management and an aggressive sinus debridement of both sides with amphotericin-B wash was also done. Despite an early diagnosis and intervention, the patient succumbed to her illness. All post-COVID patients presenting with the complaints of blurring of vision should be meticulously examined for the presence of any retinal abnormality in both the eyes as this may be a manifestation of an underlying secondary fungal infection. Early diagnosis of ROCM and management will help in reducing complications.
