Management of Allergic Fungal Rhinosinusitis Associated with Vision Loss During COVID-19 Era

The ongoing COVID-19 pandemic has given rise to unique challenges related to healthcare management. The problems have arisen due to the direct effect of COVID 19 infection and treatment or as repercussions of administrative efforts being undertaken to check the rapid spread of the epidemic. The management of some of the diseases has been hampered with the implementation of the policies like lockdown and transportation difficulties. This paper presents a series of four patients (6 eyes with vision loss) of an otherwise benign entity, Allergic Fungal Rhinosinusitis (AFRS), causing visual deterioration, managed amid the pandemic. AFRS has been known to cause vision loss by pressure over the optic nerve or its blood supply; however, a timely surgical intervention in the form of functional endoscopic sinus surgery to remove the disease and decompress the optic nerve, results in favourable outcomes in most patients. A delay in diagnosis and treatment may result in irreparable damage with the resulting inability to salvage the vision. In our series, we observed that vision recovery could be achieved in 66.7% of the affected eyes (four out of six eyes), while a poor visual outcome was observed in two (33%). The poor visual outcome was observed for the eyes with a prolonged visual impairment (4–6 months) at the time of presentation. We would appeal to the physicians to be cognizant of the adverse outcomes associated with the delayed surgical intervention of AFRS in the current pandemic scenario.
