VT can be very helpful. Basically there is more to vision than acuity. Tracking (cicadas) are very important in reading and eye teaming can be very important in many other visual/spatial tasks. I am married to a developmental optometrist and ironically enough our DD has an eye turn. So, she has had some form of VT since she was 2. Binip do you live in the US? If so, your SLP is not legally allowed to do VT (I am glad whatever she did helped but has no real training in that area). Some visual problems just increase the effort required for academics and make school tasks harder. On the WISC IV my DD eye turn issues gave her the most difficulty on coding followed by SS (processing speed cluster).
