I have eye tinnitus: https://en.m.wikipedia.org/wiki/Visual_snow_syndrome https://en.m.wikipedia.org/wiki/Visual_snow_syndrome It's so subtle that I don't really notice it in my day to day life, and with corrective lenses I experience almost no vision problems. But God damn it, there was this one ophthalmologist I had. He became convinced that I was at high risk for glaucoma and kept subjecting me to visual field tests to assess my peripheral vision. The machine he used for such tests was so ancient it still took 5 1/4" floppy disks, and it worked by shining lights of various brightness onto a plain canvas. You were supposed to stare at a point and click a button held in the hand (like a Jeopardy! buzzer) when you saw one of these lights. Well, this exercise presents pretty much the exact conditions for my visual snow to put me at a disadvantage, and that meant I had bizarre, inconsistent test results with strange gaps in my visual field. Of course, that only further convinced my ophthalmologist that I was a glaucoma risk, and when I told him about the visual snow, he just looked at me like I was from space and ordered more tests. I was so glad to find a nice, 34-year-old ophthalmologist some years later who used the air puff machine during the standard eye exam to measure eyeball pressure and found I was nowhere near having glaucoma. No visual field tests, no visual snow confounding the results.
