Yes, since your horse was trespassing on your neighbor's property where it caused damage, you can be sued.
Whether or not you can apportion fault with the homeowner is a different issue.

The horse was owned by you. You no doubt know and knew that the horse was blind, thus increasing the possible dangers by its roaming about. The duty to control the movements of the horse lies with you. You, sad to say, bear the brunt - if not all- responsibility for the event.

Yes, you can. It is not your neighbor's responsibility to keep YOUR horse out of its yard. The fact that the horse is blind makes YOUR obligation to protect both the horse and your neighbor's even greater.
