Some vision testing in front of the webcam

Some vision testing in front of the webcam

Inspired by Dr. Charles Boulet's article on the Cover Test, I  felt like doing some testing in front of the webcam. First you can see me doing some saccades, or jumping movements, going from one corner of my laptop screen to the other. I started off quite well but then…continue reading →
A wedding without double vision

A wedding without double vision

This weekend I attended a friend's wedding. I enjoyed it immensely. It was a reminder of the fact that not everything in life has to be a struggle. Not everything needs to be difficult. It's nice to see so many happy faces celebrating a joyous occasion. During the last three…continue reading →

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.…continue reading →
Some of my current home based VT activities

Some of my current home based VT activities

Everything we do or don't do has neurological consequences. That's why everything we do or don't do matters. It's important to note that these activities are not suitable for every VT patient. Nor are they suitable at any stage in the rehabilitation process. They are suitable for me because my…continue reading →
Session 75: Trusting yourself

Session 75: Trusting yourself

I had another training session on Tuesday. I did more 'feeling depth' in anaglyph pictures by reaching out for them with my fingers. It's very exciting how that keeps working. This practice also enhances physiological diplopia. That makes sense given that this ability is based on positioning your eyes correctly,…continue reading →
Setting goals for July 2015

Setting goals for July 2015

Much of VT comes down to setting small but attainable goals for yourself and then reaching them. Then doing that again, and again, and again. Three years ago a goal would be 'any reduction of the strabismus angle is a win'. The first two years I would systematically halve my…continue reading →

Football without stereoscopic depth perception (video + optometric analysis)

HISTORY As a strabismic child that suppressed one eye at the time, I played football (soccer) during every recess period at school. Clearly I had no stereo vision. Nonetheless I was a fairly good player and loved playing. I could be totally absorbed by it. At one point I also…continue reading →

The accommodative rock demonstrated

This is a video of me performing an exercise called 'accommodative rock' or a version thereof. You need a tiny letter chart to hold in your hand and another big letter chart on the wall in front of you. The exercise simply consists of alternately reading a letter from the paper…continue reading →
Session 72: In pursuit of more speed, accuracy and consistency

Session 72: In pursuit of more speed, accuracy and consistency

The foundation has been put in place. Finishing it up by perfecting the collaboration between vergence (eye movements) and accommodation (manipulation of the eye lens by your tiny muscles in the eye) and increasing capacity will be the closing deal. Major physical restrictions have been largely eliminated. More speed, more accuracy…continue reading →
