Pretty related though. Doc figures some calcified floaters have been tugging on my retina for some time and the shrinking vitreous makes it worse.

My dad had a detached retina fixed. I don't remember all the details but they filled his eye with some fluid to repair the detachment. The doctor told him he will see a bubble in the bottom of his vision. When they removed the eye patch sure enough dad said there was a bubble kinda like the ones on a level, or smaller, on the bottom of his field of vision.

It is on the bottom because the eye, like all lenses flip the image. Our brains flip the image so the world makes sense. Dad said it was almost like a pet having his bubble and it made it easy to know when his head was tilted. It slowly shrank in size and went away.

His mom lost vision in one eye, and had poor vision in the other eye from retina issues. I see a ophthalmologist and eye surgeon once per year. He know of the genetic possibility of retina issues. He always looks real close at my retinas with his huge magnifying gizmo.

I have the air bubble in there now. After one week its about half gone.

My eye is slowly refilling. On Day 7 the water level was right in my line of sight - I actually got a little seasick that day as it wobbled back and forth with small head movements. Fascinating and disconcerting.

My dad gave his bubble a funny nickname that I don't remember. He said as it got smaller he almost felt sad his little buddy was going away.

When his mom had a detached retina back in the 1960s she was in the hospital for over a week, stuck in bed, and they had her head sandbagged and strapped down to prevent her from moving. She had to have nurses feed her and clean her for the week. She said it was a horrible ordeal, but she had good enough vision to drive with huge coke bottle lenses.

I had epiretinal surgery in Dec. 2020 & relate to your post-op experience. There was a couple of days during recovery I had a double image in my eye when the gas bubble (fwiw & sounds nasty - SF6 - sulfur hexafluoride) was about half way & as per your observation, summed up my experience exactly. I was lucky as my visual acuity is now about 90% of my dominant eye.

Cataract surgery may be in your future as it became in mine. The results were quite startling & positive except for the fact, when I look in a mirror, I am somewhat taken aback by the ancient grizzled visage before me.

Best of luck in your recovery & Cheers
