Amsler grid distortion at edge after trauma and PVD

Hello,

I'm 42, highly myopic (-9) and I've had blunt trauma to my right eye in August 2020, which caused a very slight initial PVD around the fovea (after the incident, there was a very distinctive, single floater that was suspended exactly in the center of vision and moved very little, which indicated to me that the PVD had only happened in a very limited area. The floater was of course magnified enormously due to the proximity to the retina, I could actually see the individual cells with their nuclei!)

About 2 weeks ago, there was a sudden, about 1 hour long episode of intense, arc-shaped "flashing" in the periphery (toward the blind spot, i.e. nose, but obviously "seeming" to come from the other (temporal) side in the visual field), along with blackening of the central visual field (a growing and shrinking black circle that actually was synchronized with the flashing).

After this episode ended, I noticed that the centrally suspended "floater" was gone, which completed the picture for me that finally a complete PVD had occured.

During the next few days, I noticed a new peculiar, slight visual disturbance:

When looking at a dimly lit flat surface, and then closing my eye, I could, instead of the usual "flat" afterimage, see what looked like radial lines emanating from the blind spot toward the periphery.

This is only very slight, but definitely noticeable and different from the other eye, where there was just a normal, uniform afterimage.

This led me to believe that the retina might have been pulled / tented slightly, or that blood supply is slightly compromised in a "wave-pattern-like" manner. (the lines do NOT coincide with blood vessels though, even though it may sound like it.)

To further my suspicion, I've looked at an Amsler grid. While everything's fine (flat / undistorted) at the nominal distance, as soon as I bring it closer so that the peripheral vision is involved, I can see a very clear "dent" at the center right of the grid. The center of the dent seems to coincide with the point where the lines of the slight afterimage converge.

(See attached image, left side)

Any ideas if my suspicions of a slight retinal denting / detachment are correct?

Thanks!
