My brother who is sighted (wears glasses, normal nearsidedness), recently saw a specialist for scarring on his retinas. It didn’t affect his vision but the optometrist noticed it during a routine visit. They inspected his eyes and said it was nothing to be concerned with. I hope this gives you some reassurance and that everything goes well with your appointment on Thursday!

I'm removing this, as nobody here is qualified or able to give you medical advice.

It's great that you're following up with a specialist, and I wish you the best.
