Wide-eyed Wonder: an artist's musings on three-dimensional vision

Some are color blind. I am stereo blind.

Relax. Let go. Give your brain permission.

I’ve been following this VT patient’s progress reports with interest. Today’s post “Stop trying so hard and just SEE” mentions a common hurdle to diverging our eyes, the ability to RELAX those rogue eye turn-in muscles! “Stop LOOKING” my VT would often say. LOOKING to isolate something normally fixates both eyes on an object, or in my case, unconsciously fixates one eye while turning in and suppressing the out-of-alignment image of the other. “Soften your gaze” was another frequent VT exhortation.

1218randotLast week, random dots did the trick of NOT LOOKING for this VT patient, and I think I understand why. The randomness of the thing viewed eliminates the worry about getting a “right” answer, and therefore is less stressful than “Is the elephant or the fly popping out for you?” which can trigger frantic LOOKING.

Randomness is the opposite of representation, therefore the brain lets go of the need to comprehend and interpret an object. As an artist who strives to accurately represent objects, a good dose of randomness may be exactly what my brain needs to stop trying so hard.

This is why, for me, letting go also requires giving myself permission to allow a new way of seeing to emerge, to be visually open-minded.

I’m rejoicing that random dot stereograms are working for this patient to overcome her eye turn-in along with the many awesome mind-opening exercises her Vision Therapist is tailoring to wake up her brain.

By letting go and giving herself permission to see a new way, her world is opening up into the third dimension I long to experience.

 

No Better Than a Placebo

New research is tracking brain changes in patients who undergo binocular vision therapy. Combine objective fMRI data and the many blog posts by adult therapy patients, and you have exponential evidence that vision therapy works for adult patients, and is getting better and better at targeting each patient’s unique visual needs to generate success.

All you need, therefore, is a therapist with an interest in helping the adult patient with the newest cutting edge stuff like Oculus Rift who happens to be passionate about binocular vision and works with adult patients within 100 miles.

My own home-based VT with a little help from an optometrist in my village pretty much ground to a halt in October. I even cancelled my monthly visit, acting out a deplorable level of avoidance behavior I am ashamed to admit. I did manage to make a 15 minute visit in November to confess I had done nothing since September. I did not commit to more monthly visits, as I’ve not been doing any exercises.

This week’s post at The VisionHelp Blog  detailed the new neural research with a link to a TED talk by Tara Alvarez, Ph.D. In the midst of the good news was a succinct explanation for my own self-imposed hiatus:

… in the video she notes that in the landmark CITT study … home-alone therapy was no better than (a) placebo.  A significant reason for this, she speculates is that the currently available home-alone therapy is gosh-awful boring and compliance is therefore lacking.  Another potential reason is  the patient may not be doing the therapy optimally because of lack of feedback from a therapist.

Boredom plus lack of solid feedback are indeed primary causes for throwing in the towel. In addition, the exercises exhaust me. I recently read of another patient’s progress at the Mindsight blog and he/she continually admits to the need for SLEEP. I battle feeling totally fried after just 2 minutes of Brock staring. Even looking at motion parallax while my husband drives places cooks my noodle on a good day. And, while this patient is making measurable progress, I lack any measurement but my own guesstimates, and wonder if they are even accurate.

Where do I go from here? Three years ago, the Vision Therapist working under my Developmental Optometrist offered to stay in touch via email, because she is a fellow adult strabismic and was undergoing Vision Therapy to gain binocular vision at the time. I’m curious to know if she has made progress. Curious enough to contact her.

Meanwhile, I have my “Map of Fellows” grabbed from the “Locate a Doctor” search at covd.org … the closest Fellow is the Developmental Optometrist I worked with before my BRAO in 2010-11 where the aforementioned strabismic VT works. In 2010 that Fellow was somewhat reluctant to take me on (due to the dearth of data confirming adult success) and suggested a more progressive Fellow in Cleveland. My sudden blindness in March 2011 put frosting on that reluctance cake.

Cleveland is far, but a less stressful drive than going to Pittsburgh through the hills on back roads and  secondary highways. But my driving back home from Cleveland through Akron and Canton for over an hour, fighting heavy traffic AFTER the weekly brain-frying session? No. No. No. Not safe …

And so, my hiatus remains. But my interest is still on fire. That may never change.
