Son's OT tested his vision using TVPS3 And his results were wonky

[nitascool]

TVPS3 stands for Test of Visual Perceptual Skills – 3rd ed. I was expecting either off, way off, or sort of normal. But they were just wonky. He's 11 and has Aspergers, SPD, and ADHD. Not diagnosed with Dysgraphia but is to a tee for the signs and symptoms listed on Wikipedia.

These are his Raw Scores, Scaled Scores, Percentile and Age Equivalent

 

Visual Discrimination (DIS) 5, 3, 1%, 4 yrs.

Visual Memory (MEM) 11, 9, 32-42%, 6-6 yrs.

Spatial Relations (SPA) 13, 12, 70-79%, 9-3 yrs.

Form Constancy (CON) 13, 14, 88-93%, 16-7 yrs.

Sequential Memory (SEQ) 10, 8, 21-30%, 8-6 yrs.

Figure Ground (FGR) 11, 10, 45-50%, 9-8 yrs.

Visual Closure (CLO) 6, 6, 7-11%, 6-1 yrs.

 

 

Subtests Sum of Scaled Scores Standard Scores Percentile Rank Age Equivalency

Overall (includes all subtests) 62 94 34% 8-7 yrs.

Basic Processes

(includes DIS, MEM, SPA, & CON) 38 98 45% 8-10 yrs.

Sequencing

(includes SEQ) 8 90 25% 8-6 yrs.

Complex Processes

(includes FGR & CLO) 16 90 25% 8-3 yrs.

 

So he's mostly averaging around 8-9 years dipping down to 6 year and even a 4 year score and peeking with a 16 year score. I have an appointment scheduled for next month with a ped. developmental vision specialist. I'm wondering the likelihood that he will need VT or if it's a separate issue all together?
