cranial nerve 3 palsy. Ptosis of the left eye, it was completely shut; cannot hear; This is a spontaneous report from a contactable physician. A 93-years-old male patient received the first dose of BNT162B2 (PFIZER-BIONTECH COVID-19 VACCINE), via an unspecified route of administration on 22Jan2021 at a single dose for COVID-19 immunization. Medical history included atrial fibrillation, hypertension, hyperlipidaemia, diabetes, and chronic kidney disease. Concomitant medications were not reported. No additional vaccines administered on the same date of the vaccine and no prior vaccinations within 4 weeks. The reporter is the family's physician, who stated that the patient received the first dose of the Pfizer COVID vaccine on 22Jan2021 and three days later (25Jan2021), his left eye had ptosis - he was unable to open his left eye and it was completely shut. The patient came to him and when he would try to lift the eyelid up, it would just drop down. He then called a neuro ophthalmologist, he thought to himself that the patient could be having a stroke. The patient was sent to the Emergency Room and kept overnight to do CT of brain, MRI of brain, CT of orbits and MRI of neck. All tests came back normal, there was no stroke. The patient was discharged and was told to go see an ophthalmologist; the eye doctor diagnosed him with Cranial Nerve 3 Palsy. The reporter had read the consultation notes; the eye doctor "wrote 1-2 days after he had COVID and had this happen". The reporter clarified that the patient never had COVID, maybe this was a misunderstanding or typo with the doctor, but the patient just had the vaccine. The point is that the patient was diagnosed. The reporter further added that the patient can't hear, and so he will provide the patient's son's phone number. The reporter would like to know if this is a possible side effect of the vaccine and if he should receive the second dose of the vaccine as he is due in two days (Friday at 8:30AM on 12Feb2021). It was also reported that the ptosis has not gotten worse and has not resolved. The reporter added that the patient was admitted to the hospital for a full day. The patient underwent lab tests and procedures which included computerized tomography (CT) of the brain, CT of the neck, magnetic resonance imaging (MRI) of the brain and MRI of the orbits-all of which resulted normal in Feb2021.
