"Adenoviral vector vaccines, especially ChAdOx1 nCov-19 vaccine, have also been reported to cause thrombotic events in rare instances. Transient reduction in visual acuity and transient visual field defects are frequently reported post-vaccination... Here, we report a case of bilateral cortical blindness following vaccination against SARS COVID-19.
Case Report
A previously healthy male patient in his 60s presented with sudden loss of vision in both the eyes a week after the first shot of COVID-19 vaccine (Covishield®)... On presentation, the visual acuity was no perception of light in both the eyes... The patient was referred to neurology for management of stroke...
Conclusion
... Contrast Enhanced MRI revealed acute bilateral parieto-occipital infarcts. The rapid antigen test for COVID-19 was negative. Considering the temporal correlation with the vaccine shot and absence of any other precipitating factor, we hypothesized that this was probably an immunologic response to the vaccine."
