Vaccine-related retinal artery occlusion in adults: a review of the current literature
First of all, I am pleased to have an opportunity to discuss our recently published review on vaccine-related retinal artery occlusion (RAO) in adults.1 Publication and reporting bias are well known in medical research,2 and time lag bias is unavoidable in major public healthcare event as if COVID-19 vaccination.3 Our review clearly listed out the literature search methods on search engine and database used (MEDLINE and PubMed), keywords and MeSH terms applied (vaccine retinal artery occlusion), as well as the date of the search (10th January 2022).

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.

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 ...

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.
