Check-up 10: New location and slightly new approach

REMINDER: When reading on a desktop or laptop, you can have the article read to you by selecting the desired paragraph and clicking on the little speaker icon.  Check-up 10 It had almost been a year since my last optometric evaluation. This is because there have been some personnel changes in the practice where I had been going. My long time Visual Trainer, Sofie De Witte, who is also a qualified behavioral optometrist, was leaving the practice in Antwerp where she was an employee to set up her own VT clinic in her home town.…Read more …
INTERVIEW: How Bill Johnston discovered stereo vision at the age of 70

INTERVIEW: How Bill Johnston discovered stereo vision at the age of 70

REMINDER: When reading on a desktop, you can have the article read to you by selecting the desired paragraph and clicking on the little speaker icon. I first learned about Bill Johnston when, in early 2014, he posted this message in one of the amblyopia and strabismus Facebook groups. “My lazy eye turned on on New Year’s Day. I don’t have amblyopia anymore and I do have depth perception for the first time in my life. The whole world is more beautiful than I ever could have imagined. I will be 70 years old in the…Read more …

Strabismus, mobility and cycling in particular

REMINDER: When reading on a desktop, you can have the article read to you by selecting the desired paragraph and clicking on the little speaker icon. My last official VT session, for now, was on the 27th of March, 2015. Because of a personnel change at my developmental optometrist Guy Naegels' practice, I was asked to discontinue training at his office. My training optometrist, Sofie De Witte, who has been working with me for over four years, has left the practice to become a fully independent practitioner. I can still return to Guy Naegels' office for…Read more …
Aperture Rule: A Vision Therapy empathy top tip

Aperture Rule: A Vision Therapy empathy top tip

As you might know, at this point my eyes are looking pretty much normal most of the time but the inability to converge consistently remains crippling. It drains and strains a lot. It's like a massive extra backpack I'm wearing, or an invisible barrier between me and the world, preventing me from getting things done more easily. Currently, much of the time, I'm living with a male cousin named Thierry (22) and female cousin named Cynthia (26). They are very nice about my peculiar situation and try to understand. I, in turn, am…Read more …
Cheiroscope: video, drawing samples and implications

Cheiroscope: video, drawing samples and implications

After a nice theoretical post, let's get down to the nitty gritty. How can we get a tangible look into how someone perceives his personal space? How can we determine inconsistent perception of space interfering with the construction of solid brain maps? As vision writes spatial equations for the muscles to solve, cheiroscopic drawing is an interesting way to gauge the state of ocular motor ability and spatial vision. During cheiroscopic drawing, one's visual system is completely stripped of contextual aids. Broader context often helps strabismics to get around and complete certain tasks…Read more …
Jaw clenching, Vision Therapy and earthquake resistant structures

Jaw clenching, Vision Therapy and earthquake resistant structures

Personally I learn a lot from reading/listening up on vision rehab and anatomy but I learn just as much from having conversations with other strabismics. I think it's a practice that could be useful to anyone with any problem. Don't compare yourself to people with a very differing, in this case neurological, background. Learn from people who are similar to you and dealing with similar day-to-day problems. What follows is a blog post constructed on this type of conversation. PASQUALE: Hi Michael, in many blog entries you mention jaw clenching. I too have…Read more …
“Electronic Rapid Alternate Occlusion Goggles” as Anti-Suppression treatment

“Electronic Rapid Alternate Occlusion Goggles” as Anti-Suppression treatment

Following an interesting thread on Facebook and some e-mailing back and forth with Patricia Simone Fink OD and Eric Hussey OD who were generous enough to share their time, research and experience with me, I decided to make another investment in my vision in the form of Electronic Rapid Alternation Occlusion Goggles. New year, new projects and new ways of approaching existing problems! What are Electronic Rapid Alternate Occlusion Goggles? "Electronic rapid alternate occlusion (ERAO) using liquid crystal lenses is used to treat suppression of binocular vision, a defect affecting the sensory combination…Read more …

Session 79: A short Aperture Rule update

Recently a VT friend of mine named Pasquale asked me how I had progressed in executing the Aperture Rule ever since I wrote 'Doing time' two years ago. Last week I asked my Vision Therapist whether I could try the AR again to verify.   Two years ago I only recently started having single vision some of the time. Back then I was able to execute the AR up to level 4 (of a total of 12) both with the exo and eso settings.   Right now I am able to execute the…Read more …

Session 76: Bring in the periphery

Skills acquired so far: - Smooth eye movements, improved vergence amplitudes and eye alignment - Improved accommodation amplitudes and continuing improvement with flippers - Stabilizing Vestibulo-Ocular Reflex - Being able to judge depth using physiological diplopia and reference cue Left to do: - Automation and stamina - Integration, integration, integration. - My VT seems to be expecting I'll see some float in the Vectograms rather soon. To accomplish this I have to widen the span of my visual field.  That's hard for me. Most of my life I've been busy suppressing my peripheral…Read more …
