Hi everyone,
To start with, I'm a 20 year old healthy female. I few nights ago something really strange happened to me when I turned out the light to go to sleep. A few minutes after I turned the light off, when my eyes should have adjusted to the dark, something didn't seem right with my vision. So I covered my left eye with my hand, leaving my right eye open, and everything went pitch black. I couldn't see anything out of my right eye. With my left eye I could see the shapes and shadows that you can usually make out in a dark room, but out of my right eye was just total pitch blackness. I turned my light back on, and everything was completely normal; I could see with both eyes. Then I turned the light out again, and once again, I had vision in my left eye but not in my right.
This happened a few nights ago, and it hasn't happened again since. This is probably irrevelant but I thought I'd mention it- I have a couple of enlarged lymph nodes as well as a swollen tonsil on the right side of my neck/head that have all been checked out by a doctor. I also have a new lump on the top of my head, also on the right side. As I said, this is probably all irrevelant to the vision problem, but I thought that maybe since all of this is on the right side of my head, which is the same side as the problem eye, it could somehow be involved.
Does anyone have any ideas of what could cause one-time temporary night blindness in one eye? Thank you for reading!
