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 →

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.

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 →

Interestingly, my strabismus was developmental since the age of three but in a relatively short amount of time I lost many of my adaptations (suppression, strabismic ways of eye teaming) to cope with misalignment of the eyes. First my suppression gradually declined because of life style, i.e. overly zealous studying,…continue reading →

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 →

"Right after I lost vision in my eye, I was so bad at walking that I ran into a girl eating ice cream, and knocked her cone out of her hand. She screamed: ‘Are you blind!?!?’ I turned to her and said: ‘I am blind actually, I’m so sorry, I’ll…continue reading →

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 →
