I am not seeing the correlation of this behaviour with an eye problem. Of the senses sight is the weakest, Smell and hearing are the dogs strongest senses, dogs do not actually see as well as us and their sight is better at dusk then any other time of day.
Your dog would recognize the sound and smell of you before the sight of you a block or two away.
This sounds neurological, hence why I asked about shots. Possible your dog is suffering from vaccinosis....a vaccine reaction. This started 6 months ago. IS that when she had it done - rabies that is. It doesn't always manifest as a visible reaction in an hour, day or week....symptoms can come on later months later. That is why it is usally poo poo'd as a cause and dismissed. Vaccine reactions are severily under reported do to this.
Vaccine's contain harmful adjuvants to stimulate the immune system. These things such as aluminum (all vax.), mercury (in rabies), Formaldhyde, MSG, can cause neurotoxicity. Aluminum can pass the blood brain barrier (not too many things that can), where it stays.
This could also be a symptom of MDR-1 mutation. There is a gene which is responsible for removing harmful drug deposits from the brain. In an MDR-1 dog, this is not possible. This can lead to a seizure disorder, and I would think aluminum and mercury would be right up there in this type of disorder...may exacerbate.
Now some are going to jump on here and say it is prodominantly a Collie disorder, but it is a "herding" breed disorder, and it is likely due to GSD's not falling into this category, that people are not advised by vets to test for. Again, under reported. So vets manage Idiopathic seizure disorders with drugs, but still stick vacccines in them.
One of the causes of MDR-1 reaction is Ivermectin or type of, such as found in heartguard, revolution etc. and is on the "confirmed" list of MDR-1...as well as some other that do not contain these and fall under the "suspect" list. To note, this doesn't have to have an immediate reaction either, this can build up over time.
I will dig up some articles for you to consider on the subject of vaccinosis and MDR-1
Seizures come in different forms...not always grand mal, they can be petite mal....such as frozen on the spot and staring w/o recognition...any staggering in your dog?
He is your friend, your partner, your defender, your dog. You are his life, his love, his leader. He will be yours, faithful and true, to the last beat of his heart. You owe it to him to be worthy of such devotion. - Unknown
