Transient unilateral blindness following general anaesthesia: case report

Abstract

A case is reported of transient unilateral blindness following general anaesthesia with a face mask. The most likely explanation for this is central retinal artery occlusion, either partial or complete, due to excessive pressure from the mask exerted on the globe. This pressure may be increased with the use of neoprene head straps as opposed to the more flexible and elastic rubber straps. Pressure from the strap over the carotid artery may be a factor in reducing the central retinal arterial pressure, thus making it more susceptible to occlusion by mask pressure.

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.
