Susac syndrome complicating a SARS-CoV-2 infection
We present a case of a 40-year-old man diagnosed with Susac syndrome after COVID-19, presenting with acute sensorineural hearing loss, encephalopathy, a splenial “snowball-like” lesion, and branch retinal artery occlusions with distal arterial wall hyperintensity. Although the pathophysiology of Susac syndrome remains unclear, this case is in line with the ongoing debate about the influence of SARS-CoV-2 on the human immune system. Corticosteroid treatme nt was initiated, followed by two treatments with rituximab, with clinical improvement of the symptomatology. Maintenance treatment currently consists of mycophenolic ...

SARS-CoV-2 Impairs Vision
Conclusions: This mini review shows that impaired vision may be the initial manifestation of COVID-19, that all sections of the visual tract may be affected and causative for visual impairment in COVID-19 patients, and that SARS-CoV-2 manifests along the visual tract with ischemia, focal infection, and immunological reactions.

The potential role of microvascular pathology in the neurological manifestations of coronavirus infection
We present the hypothesis that pre-existing vascular damage (due to aging, cardiovascular disease, diabetes, hypertension or other conditions) facilitates infiltration of the virus into the central nervous system (CNS), increasing neuro-inflammation and the likelihood o f neurological symptoms. We also discuss the role of a neuroinflammatory cytokine profile in both blood–brain barrier dysfunction and macrovascular disease (e.g. ischemic stroke and thromboembolism). Future studies are needed to better understand the involvement of the microvasculature in coronavi rus neuropathology, and to test the diagnostic potential o...
