Hello again, and thanks for your reply with additional information.
While VKH-like syndrome in humans can also cause deafness, this is not usually as typical in dogs. However, severe eye pain is a key symptom of this condition, so flinching when you pet her near her left eye, is indicative of irritation or pain. Giving her the Metacam for pain, was a good move on your part, but since she's exhibiting more symptoms since she saw the vet a short while ago, she needs to be evaluated again, ASAP. Retinal detachment and other eye conditions, to which canines are prone, are always possible, but severe pain, decreased vision, and skin and fur lightening are typical symptoms of VKH-like syndrome. You can read more about it, here:
The Akita breed IS prone to this condition.
It would be best for your to bring your dog to a veterinary ophthalmology specialist to assess her current symptoms. If your vet can't make a referral, check here (if you're located in the U.S.):
Veterinary specialists can also be found in ER vet centers and veterinary colleges.
I hope you're able to have your dog definitely diagnosed and treated, so she's not in pain, and some of her vision may be saved.
