I think it's great that you're trying to understand your injury and advocate for therapies. If you wait for the experts...

The category of visual-spatial impairment covers a very wide variety of symptoms/impairments, such as being inattention to areas of your visual field (like me), convergence issues, reading difficulties, inability to recognize colours, etc... Helpful therapies/workarounds vary depending on the impairment(s).

The next time you're at the doctor, you might ask him/her to explain your particular spatial issues. He/she might decide that you should be examined by a neuro-optomologist.
