I would be more interested in hearing what a behavioral optometrist says regarding the vision issue. My DS7 was born with visual deficits and had 2.5 years of vt between 4-6 years old.
My son's former behavioral optometrist could tell DS was a couple of grades ahead of his peers from examining him. This really didn't sink in until he started to show signs of PGness. I shudder to think what would have happened if DS didn't have the VT. The results have been dramatic and absolutely incredible.
I remember DS's former behavioral optometrist telling us about an older kid who was very depressed and most likely suicidal before he started VT. This older kid was bright but struggling in school and in particular with reading. Behavioral optometrist told me he advised the mother to find a primer/phonics book and start from scratch teaching the older kid how to read.
I'm telling this tale because it would not surprise me if your DS is getting a bottleneck with the vision issues and is getting quite frustrated from it. DS7 wasn't overly depressed either before VT, but he had a hard time too. I can say that it improved quite a lot with VT, though it took 6-8 months before we had the first major breakthrough from it.
