It may not be as hard as you think to home a visually impaired dog. There are people who almost specialise in taking in rescue dogs with disabilities of one sort or another - they make a point of giving homes the dogs that no one else wants, and often they have a lot of experience. So if you could foster her for a while, it would give you some time to find such a person.
Or you could just wrap her in brown paper and send her across the sea to me
