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…continue reading →
The visual system’s important role in figuring out where you are

The visual system’s important role in figuring out where you are

Developmental strabismics often learn how to suppress sight coming through one eye. Many times they even learn how to alternate between both eyes. This is a useful short term neural adaptation but has many disadvantages in the long haul if not corrected. Having been, and to some extent still being,…continue reading →

VIDEO: Current convergence status + The ‘time-of-day-effect’

For a previous post I uploaded a video recorded in December, 2011 and went on to compare it to a video captured in May, 2014. The images were self-explanatory and it was pretty spectacular! I recommend for anyone with strabismus to make videos of their eyes. It's great to monitor…continue reading →
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 →

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 →

You want more evidence? I’ll give you some evidence right here.

“Every man can, if he so desires, become the sculp­tor of his own brain” - Santiago Ramon y Cajal (1852–1934) Ever since I was four years old I've been cross-eyed (accommodative esotropia). My brain learned to suppress the image of one eye by turning the eye inwards. Over the years…continue reading →

Strabismus and academia

Yes, so what about it? Well, it's complicated. I will try to explain it though. It's important to understand that my vision never could be relied on and it was always changing over the course of time. Initially as a first grader I had trouble learning how to read. At the…continue reading →
