Isolated and Combined Unilateral Central Retinal Artery and Vein Occlusions After Vaccination. A Review of the Literature
Retinal artery occlusion (RAO), especially central RAO, is a sight-threatening and potentially blinding ophthalmic emergency. Recent publications reported its association with coronavirus disease 2019 (COVID-19) mRNA vaccines. Although rare, vaccines have been linked to ophthalmic complications, and it is of interest to examine the current literature on vaccine-related RAO.

Comments on Coronavirus Positive Patients Presenting with Stroke-Like Symptoms
We read with interest the short communication entitled “Coronavirus Positive Patients Presenting with Stroke-Like Symptoms”,1 it was a case series on stroke presentation over COVID-19 patients. We are particularly interested on patient 10, the one and only one central retinal artery occlusion (CRAO) case secondary to occlusive thrombus in the intern al carotid artery (ICA), who was also highlighted by the authors. CRAO is a blinding ocular emergency, and a harbinger of ischemic cerebrovascular stroke.

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...
