That means you were given some "happy juice" so that the pain of the retrobulbar and modified van lint or nadbeth block didn't bother you.
You had the type of anesthesia that was outlined by the picture I gave you.....
The blood on the patch would not have come from behind the eye; most likely it came from the conjunctiva where you were given the garamycin and celestone.
As to what happened to the optic nerve, that is an excellent question. The only way to be 100% sure would have been to directly look at the nerve by opening up your orbit

Could your optic nerve have been impacted by the retrobulbar injection? Yes. What is the chance of that? About 0.05% -- a very small, but real, chance.
