Rapid Progression of Polypoidal Choroidal Vasculopathy following Third BNT162b2 mRNA Vaccination

Abstract

The study aimed to describe a case of rapid progression of polypoidal choroidal vasculopathy (PCV) following the third administration of the Pfizer-BioNTech (BNT162b2) mRNA vaccine. A 79-year-old Japanese man visited our hospital with a 1-week history of blurred vision in the left eye 16 h following the administration of the third BNT162b2 mRNA vaccine. The clinical examinations and imaging tests revealed massive submacular hemorrhage (SMH) and excessive subretinal fluid (SRF), owing to PCV in the left eye. No ocular abnormality was observed in the right eye. His medical history included diabetes and ocular history included cataracts, nonproliferative diabetic retinopathy, glaucoma in both eyes, and irregular retinal pigment epithelium elevation in the left eye. Since he received a single intravitreal injection of aflibercept approximately 2 years ago for the treatment of diabetic macular edema in the left eye, the left eye was stable. We performed an intravitreal injection of bevacizumab and combined phacoemulsification with pars plana vitrectomy with gas, including subretinal injection of tissue plasminogen activator to displace the SMH. Thirteen days after the surgery, the SMH and SRF decreased. Although rare, mRNA COVID-19 vaccine administrations could be associated with PCV deterioration.
