one-time night blindness in one eye

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!

I had this too after reading on my iPad. I switched to sepia but it did not help.  After first episode I got a PVD and a Weiss ring floater.  I'd been to retina specialist and he said nothing could be done but I went to California and got floater zapped with laser. They did say 90 % that right eye would ge PVD too.
Last night I got the right eye not adjusting to dark and feeling of blindness after reading on iPad.  The retina specialist did say I had cobbling of the retina.  I wonder if these so called retina displays on the iPad could be damaging to the retina.  I'm 56 and had the first PVD ( Post Vitreal Detachment ) at 55. That's kind of young for this type of thing.  Makes me feel like I'm having a stroke.

IPads and iPhones and computers and video games do not damage the eye or cause PVDs but can cause eye fatigue and discomfort and is causing a worldwide increase of myopia. so much so that by 20/50 it is estimated that half the world's population will be myopic

Yes it would be extremely rare and my feeling is it was not an early symptom of a RD or PVD.

Lat year I had this a couple of times over the course of 4 or 6 weeks. Each time, after turning off the light at night, my left eye was briefly blind, then gradually recovered vision (my bedroom is not all that dark). If I turned the light back on, my vision in that eye was normal. Frequency and severity gradually decreased and it then ceased completely. I had my eye/retina checked and it was found to be fine. The odd thing is that about 6 months later I first had symptoms of vitreous detachment in that eye which in turn caused a retinal detachment 10 days later. This makes me inclined to think that the original thing may have been some early symptom of the vitreous detachment (which is usually harmless). Ophthalmologists are not sure, as it seems to be quite a rare phenomenon. I'm female and 58.

Dear John

Sorry to bother you but does the '=' sign mean anything?

Thanks
