What Causes Seeing Of A Shadow In The Visual Field?

default
Posted on Sat, 2 Jul 2016
Question: A few weeks ago I noticed when I closed my right eye a dark shadow appeared from the bridge of my nose into about a third of the visual field of my left eye. After some experimenting I have come to believe what I am seeing is the eye lid of my right eye.... Is this possible? Would my left eye be "seeing" input from my right eye? I experimented with this by placing a tube over my right eye flush with my face and with that eye closed I shined a light in the tube. Sure enough the same place the shadow appeared was filled with a light. I saw an ophthalmologist today because I also have pain in my left eye around the socket and when I move the eye. He said the retina is healthy and the optical nerve looks fine and that he has never heard of anything like I am describing. I guess I am just wondering if anyone has any idea what it might be?

I am not actually asking if I should be worried about it, I'm asking for an explanation of what is happening to cause a shadow to appear in my left eye when I close my right eye.

Brief Answer:
Unexplained visual phenomenon

Detailed Answer:
My dear,

Please get a field charting to rule out any organic reason for your complaint. If a defect is seen on field charting then explanation can be offered, if no defect is seen and fields are normal, that will mean tests do not substantiate your complaint.
