Reversible neuropraxic visual loss induced by allergic aspergillus flavus sinomycosis

This work reports a patient with visual loss treated successfully with surgical removal of the Aspergillus flavus sinomycosis. Vision was partially reversed within hours after surgery before starting planned corticosteroid therapy. The patient's visual acuity continued to improve steadily until it became equal to that of the other eye. The immediate gain ii? vision and continued improvement without corticosteroid therapy suggest a new hypothesis for visual loss induced by allergic sinonasal Aspergillosis. Simple mechanical pressure alone of the aspergillus mass over the nerve can produce visual loss, and this loss is reversed by removing the mass without corticosteroid therapy.
