[detached-retina] Scleral Buckle Shadow or Optical Nerve Stroke

I had the Sleral Buckling surgery 5 weeks ago and suspect to see the
buckle shadow in my peripheral vision, which consists of a big
circular ring along the whole field of vision and a particular darkish
dot at 6'oclock.

Searching the internet and find a person described a similar situation
after the buckling surgery and the doctor thought it may be the buckle
or due to a stroke of optical nerve - this is pretty scary.

So I want to listen to you guys experiences on buckle shadow or
optical nerve stroke after the buckling surgery and understand more
about my condition.

Also, my doctor said as I had congenital cataract some 30 years ago
without IOL implantation, so I may see the buckle because of
refraction differerence without the lens, I doubt it though.

Any comments and sharings would be more than welcome!
