If I fix my gaze on an object, and then move my head down while continuing to look at the object with my eyes, I then see a circular grey spot grow in size the further I move my head. The grey spot seems to be centered directly over my natural blind spot in the eye, interestingly. Then, if I fix my gaze again, but this time move my head right, then I see an arc shaped scotoma that lights up bright, located just to the right of the circular grey scotoma.
I have an epiretinal membrane growing in this eye that the doctor says has started to pucker and cause traction. Interestingly, he said the membrane was off to the size of the macula. I'm wondering if the membrane is growing over the optic nerve and interfering with it or even damaging it by putting pressure or traction on the optic disc or thin retinal cells around the eye's natural blind spot (given the visual phenomenon I described above)?
Has anyone heard of a membrane needing to be removed because it's harming the optic nerve / optic disc? What else could be causing the scotomas I'm seeing? These are new phenomenon that I'm sure just started happening recently. They're quite noticeable.
