Abstract

Purpose
We report a case of neuroretinitis combined with external ophthalmoplegia in a patient who developed a cerebral venous sinus thrombosis after administration of a SARS-CoV-2 vaccine.
Case summary
A 26-year-old woman who was on oral contraceptives was diagnosed with a cerebral venous sinus thrombosis 1 month after the first injection of a SARS-CoV-2 vaccine (BNT162b2, Pfizer-BioNTech). The levels of factors 8 and 9 were elevated on the blood test. The corrected visual acuities were 0.3 in both eyes. A complete limitation of abduction and esotropia were evident in the left eye. Both eyes exhibited optic disc swelling and hemorrhage and retinal nerve fiber layer swelling. Subretinal fluid was apparent in the right eye. Three weeks later, the optic disc swellings and hemorrhages had worsened and both eyes evidenced macular stars. After 10 months, the corrected visual acuities improved to 0.9 in both eyes. Ocular motor function and the esotropia also improved. However, the overall contraction of the visual field did not.
Conclusions
SARS-CoV-2 vaccination can trigger cerebral venous sinus thrombosis, neuroretinitis, and external ophthalmoplegia. In patients with risk factors for such thrombosis, the possibility of ophthalmic complications should be considered after administration of a SARS-CoV-2 vaccine.
