Err kind of worried-I dont know what exactly to think :S

Maybe a trip to the vets to see if there is anything they can do for her to prevent her going blind for a while longer, I think its reasonable for dogs to get a little grumpy when they are getting older but I still dont believe its ok for them to bite I would keep people away from her and warn them to be gentle with her and not to creep up and scare her that way they got their warning.

Yes, it is your responsibiity to warn visitors that she may be blind, and not to startle her. She can live a long, happy life still if you - the humans of the house - adjust your expectations for her.
