“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…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 →
Strabismus, visual field loss and visual-spatial neglect

Strabismus, visual field loss and visual-spatial neglect

"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 →

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 →
Head rotations, bar reading and bring on the prism flippers

Head rotations, bar reading and bring on the prism flippers

  Head rotations Last week, for the first time, I had a completely stable percept while doing my head turns. I couldn't believe it!  I thought I was suppressing or something but I wasn't. Both eyes were just heedlessly adjusting to the head movements without error. It must be great…continue reading →
Alternation, cyclopean eye and the attentional spotlight

Alternation, cyclopean eye and the attentional spotlight

As my eyes are aligned most of the time by now I have no real concept of alternating between both eyes anymore. Despite the mechanical alignment of my eyes, I still do not use them equally. My vision still seems to be rather lateralized to the right. When I intentionally…continue reading →
Pursuing a higher degree of visual freedom

Pursuing a higher degree of visual freedom

In my last blog entry I talked about 'visual reserves' and how important this concept is for long term comfort and for VT to be successful. The improvement of eye lens focusing and eye movement amplitudes individually is not enough for it to stick. You need to be able to…continue reading →
Improvement of accommodation and vergence amplitudes is not enough

Improvement of accommodation and vergence amplitudes is not enough

I was going through my things and found a piece of information I vividly remember reading and highlighting two years ago. I was very excited to see something I already intuitively grasped written in the 'Optometric Clinical Practice Guidelines ' for dealing with 'Accommodation and Vergence dysfunction'. What an emotional…continue reading →
Convergence Insufficiency, new glasses and gravity

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 →
Book review: Fixing My Gaze by Susan Barry

Book review: Fixing My Gaze by Susan Barry

After I read 'Fixing My Gaze' for the third time in three years I decided to write a long overdue review about the book that got this whole VT party started. I first read it during the summer of 2010. At the time I was undergoing all kinds of personal,…continue reading →
