This post dedicated to OTs everywhere in celebration of Occupational Therapy Month!
At first when I read this, I was couldn’t understand why someone would have a bilateral parietal incident was beyond me. When I think parietal, I think the sides of my head. So how could someone have ONE area of damage that was small and yet involved both polar sides of a brain? I also associate vision with the occipital lobe, not the parietal. But then I found the picture above. Now that makes sense. Of course the parietal lobe comes to the medial sulcus too… and of course it does meet up with occipital lobe… and of course it would probably have some connections with said lobe giving it some visual cells too.
So through daily “perceptual re-training of binocular fusion” over a 3 week period, the patient EH was able to regain depth perception. Binocular fusion is what happens when your brain takes the picture each of your eyes is giving it of a particular scene and then stitches them together into one image which creates 3D vision or depth perception. Which is kind of important if you want to drive, or not miss the table you set your Coke down. The re-training occurred with 3 different pieces of equipment: prisms, vergence trainer and a cheiroscope. None of which I know what they are really. But here’s a picture of cheiroscope.
Since it is also Occupational Therapy Month, and they are usually the ones I run to for vision things in rehab, perhaps there’s an OT out there that knows what these items are and can enlighten us on how they work? Yes, I will dedicate this post to them and hand the rest of it over. 🙂
