I'm a pregnant 27 year old woman. Last night I woke up from a panic attack and shortly after I experienced blurred vision. It was only in my left eye, no slurred speech, no numbness or tingling

Evaluation. Please seek medical evaluation as soon as possible. Some medical causes of these cluster of symptoms can be severe.
Your . Your doctor should be notified right away. He/she will let you know if they want to see you sooner rather than later. If the vision returned quickly that is a good sign. However panic attacks during pregnancy should be managed by a medical professional. If your doctor is unaware of your history, now would be a good time to disclose this information. Best of luck to you.
