Hi! I'm a 28yo female, 165cm, 72kg (158lbs), an Asian living in Asia. I don't have any pre-existing condition nor taking any medication.

My problem is that I've had this temporary vision loss in my left eye. It just came suddenly when I was sitting. It was like a gray curtain covered my eye. It lasted for about a minute. No dizziness, no headaches before and after, and it wasn't painful.

I went to the doctor the next day. Ran some tests and all tests came out okay. Come a year after, 5 more episodes happened. Same thing still, left eye covered by a gray curtain and lasts for a minute. The strange thing is that it always happens when I'm having a menstrual period. Is it because of the hormones? Or is it something else? What doctor should i go to since my eye results turned out okay. Thank you!
