Same.
My DS10 is awaiting assessment for autism, dyspraxia and ADHD. As is procedure in our area, a QTVI came to see him at school and immediately flagged him for CVI. It was a complete shock as he goes to the optician regularly and wears glasses, but being a neurological condition his visual impairments were not picked up. This was back in October. He has not been seen by the paediatric opthalmologist yet as the QTVI is building a report to send to the paediatric opthalmologist. It's a slow and frustrating process, knowing that he has CVI but not having a diagnosis.
The QTVI has been very supportive, although she's of course very busy. Fortunately DS already has an IDP (Wales equivalent of an ECHP) and the school has started to make adjustments. I don't think he has dyspraxia or ADHD but I still think he has autism.
In the time since I was told he has CVI I have read up on it. We were given no information. I've watched most of the videos on CVI Scotland and found the lessons so helpful. It's such an unheard-of condition and it's a lot to get your head around. https://cviscotland.org/
I did the Parent Pathways online course with the RNIB which was fantastic for helping me accept his visual impairments and for understanding that we are not alone. I found it- I'm still finding it- such a shock and have found that family and friends are not always willing to learn about or support the condition.
I also hooked up with RSBC and they offered emotional support sessions online for my DS, he'll be starting that soon. I'd check out Guide Dogs and CVI Society too.
Best of luck, I hope your DS is ok? Please let me know how you get on.
