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…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

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 →

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 →

Matan Drumer on living with and overcoming Convergence Insufficiency

Previously I wrote about how lately my situation more resembles a Convergence Insufficiency profile rather than a manifest strabismus profile. Most of the time my eyes are grossly aligned and I'm aware of both images although I do have some remaining surround suppression. My cyclopean eye is also still somewhat…continue reading →

Convergence Insufficiency, new glasses and gravity

Recently a fabulous piece of research titled 'Association between reading speed, cycloplegic refractiveerror, and oculomotor function in reading disabled children versus controls' by Patrick Quaid and Trefford Simpson came to my attention. It, as many other optometric research, confirms in immaculate detail the importance of vision in reading and learning.…continue reading →
