Follow the advice given- you were seen so quickly because you are in danger of losing your sight, and no amount of exercise is worth that.
Yes, I had similar issues but it wasn't that serious (although my GP referred me straight away) and I am now fine but do remember those 'spiders'.
Keep up with gentle walking but really, I would do nothing until they tell me it is safe to exercise.
I’ve not had this issue, but would ditto this very good advice and also wish you luck 🥀
