Had this past week an issue with eye and he was taken to the ophthalmologist. Ophthalmologist said he doesn't know what caused it. It seems like the oxygen was cut off to a blood vessel in his eye and there was a white spot in patient's eye showing where the oxygen was cut off and the lack of blood going through that spot. He recommended going for blood work, a complete physical, and seeing a cardiologist. Patient is in the process of doing that. Patient did not visit the emergency room for the events, but he visits the physician office (ophthalmologist). Patient did not receive any other vaccinations within four weeks prior to the first administration of Covid vaccine. Patient was healthy at the time of vaccination. My son, 3-4 hours before his vaccine, took Tylenol, would that decrease the potency of the dosing effect? The patient underwent lab tests and procedures which included weight: about 165-170 on an unspecified date. Outcome of oxygen cut off to blood vessel in his eye was resolving and remaining all events was unknown.  The lot number for the vaccine, [BNT162B2], was not provided and will be requested during follow up.
