Dr Bettina Hohberger, an ophthalmologist at Erlangen University with expertise in glaucoma, believes that looking at the eye – an area of the body where the blood vessels are visible – is representative of the rest of the human body.  She has seen that there is a change in blood vessel density in the eye of her patients with Long Covid and believes that this blood vessel density could be part of the key to unlocking and treating Long Covid. Her belief is that Long Covid falls into three subgroups - Autoimmune, Viral Persistence & organ damage from severe acute COVID-19.  She is currently studying the development of diagnostics to identify these subgroups, and has used a targeted autoantibody neutraliser - BC007 - to successfully treat four Long Covid patients to date.  Further trials are taking place soon.Living with Long Covid?
