The events "double vision" and "4th cranial nerve palsy" were evaluated at the emergency room visit. Went over his symptoms. Red flag goes up that maybe the double vision is a sign of a stroke. He went through a whole bunch of questions. Nurse advised she doesn't think this is a stroke. The nurse from his primary care office doesn't think caller had a stroke, but that something is going on and it could be 4th cranial nerve palsy. Was advised to contact his Ophthalmologist. because he had cataract surgery. Relayed his symptoms to the Ophthalmologist who also thought 4th cranial nerve palsy and advised caller to go to the ER. He went to the ER. He was kept in the ER and then admitted. Then had a bunch of different doctors come in and check for different things. Doctors unsure of what's going on. He's talked to his doctors and was told there's nothing they can do about the double vision at this point other than they think it's the 4th cranial nerve palsy. Spoke with a neuro optometrist who also thought it was 4th cranial nerve palsy. This Neuro Optometrist passively said it could be related to the COVID-19 Vaccine booster, but he didn't think so. Nothing can be found cardiovascular wise, no TIA, and nothing nerve wise in his head. The patient underwent the following laboratory tests and procedures: computerised tomogram (CT scan): (24Oct2021) everything came back clean; echocardiogram: (24Oct2021) everything came back clean; magnetic resonance imaging (MRI and MRI-A both with and without contrast on both orbits): (06Dec2021) negative, notes: nothing was found.
