Never had it in a dog, but a grey foal of ours ,out of a chesnut mare ,was born with micropthalmia once, some years back, and was obviously blind. The dam, who had foaled four times before, and was a good mum, realised that there was something dramatically wrong, and actually killed the foal. Most upsetting, but I suppose nature in the raw.
We actually blamed a cocktail of herbicide and fungicide which our neighbour had sprayed in the next door field the very day (day 42 of gestation) that the eye buds were forming in the foetus. I believe there is ongoing work on the same subject in humans.
Don't suppose this helps much with your Akitas, but thought it was of interest. Good luck with them
