Is my partner's swollen wisdom tooth causing blurred vision?

Hi doctor,

My partner has been experiencing a lack of focus in the eyes (both) for about a week now. It is not double vision or seeing things; it is just not being able to focus on something, especially letters, and the smaller the font, the harder it is for her to read, no matter the distance. We went to an ophthalmologist, and he said there is nothing wrong with her eyes or behind the eyes. He used some special drops to see behind the eyes.

We went to a neurologist, and he said he could not land on a diagnosis from her description, and he will scan her on Monday for optic neuritis. Today she woke up with a swollen wisdom tooth (the lower left one) and a lot of pain. She took Nurofen Express, and her dentist prescribed Noprilam antibiotic. Later in the afternoon, she started feeling dizzy. At this moment, I feel desperate for answers, as we have none so far! Please tell me, could this be connected with her vision?

Kindly help.

Hi doctor,

Thank you for your response. Regarding the dizziness, it went away last night and might indeed have been from the tooth pain. The vision remains the same, although she noticed that in the day, when there is light, it is worse. For example, if she looks at something bright or at the sky in the day, the symptoms become worse, plus when she tries to read something with small letters, her eyes become tired very easily. When it is dark, it is kind of better. Maybe it is important to note that the first day it started, it was firstly a sensitivity to bright lights and then developed into a lack of focus and seeing still things move about. Do these things point you to anything that could be causing this? Is there anything else we can try and do, say if the test comes back normal tomorrow and the issue remains the same? Thanks again.

Thank you doctor,

We have done the optic neuritis test, and it came out negative. Then we did the brain MRI, and as soon as it came out, the neurologist told us that there was nothing wrong. He prescribed some Methylcobalamin (B12) for her and told her to relax. We also talked with the gynecologist and said she should stop taking her contraceptive pills as they might have a risk of creating thrombosis. After two days, the neurologist called us and told us they actually found something in the brain MRI, and we went to visit him again. They diagnosed a white shadow close to the optic nerve. From my understanding, they said that it might be inflammation. But it may also be nothing. It may be related to the symptoms she is having now, or it may not be related. She did a second MRI on the next day, lasting only about 8 minutes, but this time with a liquid (which I believe is a contrast agent) to show a highlighted version and a clearer image. They said that it is still not clear whether it is inflammation or not. Then the neurologist advised having a 3-day cortisone injection therapy lasting 2.30 to 3 hours per day of injecting 1 gram of cortisone per day. The vision of my partner remains the same without any changes or improvements. The neurologist told her to do an optic neuritis test again to see whether there is anything different, and the brain MRI again in 15 days. It has been more than two weeks, and we do not have an answer. What should we do?
