Delayed Visual Development: Development of Vision and Visual Delays

Delayed Visual Development: Development of Vision and Visual Delays

The ophthalmology community doesn't have the best track record in treating strabismus or visual delays but if one of their sources come up with useful and undogmatic diagnostic information, I gladly share it. This is such an instance. https://www.aao.org/pediatric-center-detail/delayed-visual-development-development-of-vision-v   I summarized some useful insights from this article on early visual milestones I summarized here: "1. (birth) Delay in eye contact: Delays in visual communication can be noticed as failing eye contact in newborn infants. Delay in development of eye contact is usually caused by weak or no accommodation or high hyperopia (FARSIGHTEDNESS), which…Read more …

INTERVIEW: “At age 58 I can finally see properly for the first time ever. I am finally at peace.”

MICHAEL: Hello K! Who are you and where do you live now? K: I was born in 1958 in the Cherokee Nation in the state of Arkansas. My ancestors were from the Eastern Band of Cherokees and migrated south from the Trail of Tears. I lived there from 1958-60  when we moved to Albuquerque, New Mexico, which is close to The Four Corners Area. I was adopted into a Hopi family from that region later. In 1966, my family moved to Oahu, Hawaii. My childhood and youth in Hawaii were pretty tough for various reasons.…Read more …
Herb Black: Geologist turned Optometrist after 3D vision discovery

Herb Black: Geologist turned Optometrist after 3D vision discovery

"I had never had 3D vision, but didn't really know it until I was an adult. I noticed I had no 3D vision because, as a geologist, my colleagues would look at stereo pairs of aerial photos, fuse them in free space or with a viewer, and see 3D. I could not do that at all. It was a real mystery to me how they could do that, especially in free space without a 3D viewer. My daughter had binocular vision problems as a child and was helped tremendously by optometric vision therapy here in…Read more …

“As I see in much more stereo, I feel much more calmness in my brain”

"I still have strabismus, but I am relearning to see in 3D. When I am able to use both eyes and see stereoscopically, I can really sense much more depth. I think that the visual system innately ties into the brain to create a spatial effect. It really does look much more full to me. I also really sense the spatial awareness. As I see in much more stereo, I feel much more calmness in my brain as well. Strabismus causes a lot of tension in my neck, upper back and shoulders. I…Read more …
INTERVIEW: How Bill Johnston discovered stereo vision at the age of 70

INTERVIEW: How Bill Johnston discovered stereo vision at the age of 70

REMINDER: When reading on a desktop, you can have the article read to you by selecting the desired paragraph and clicking on the little speaker icon. I first learned about Bill Johnston when, in early 2014, he posted this message in one of the amblyopia and strabismus Facebook groups. “My lazy eye turned on on New Year’s Day. I don’t have amblyopia anymore and I do have depth perception for the first time in my life. The whole world is more beautiful than I ever could have imagined. I will be 70 years old in the…Read more …
The margin of error

The margin of error

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, and then the way my eyes moved and alternated was abruptly changed through eye muscle surgery. This left me without any reliable adaptation to deal with my abnormally developed visual system. So the only option then, is pick up the pieces and start…Read more …
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 ability to control my eyes has reached a level allowing me to handle these activities without imploding, albeit with appropriate rest. Getting to this stage has taken a long time. I've had to do a lot of boring ground work first. Expanding the…Read more …
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, seeing the object of interest single and everything after it double. When my hand is singled out and the object of interest is singled out, that's where it should theoretically be in space. It isn't really, because it's just an anaglyph stereogram of…Read more …
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 strabismus angle until I saw my first single image in years. After that, I would have to solidify by increasing binocular motility and improving my vestibulo-ocular reflex (VOR) so single vision can be sustained while moving. That's what I've been doing the last…Read more …
Things that make you wonder…

Things that make you wonder…

This morning I went for an eye-hand basketball training session at the local public basketball court. Near point fixation for better reading skills is my priority but you can't focus on that all day because then it gets counter productive. On the court next to the one I was occupying there was a tall, black kid also throwing some baskets etc. We just did our thing, observing each other.  I'm pretty good at throwing baskets and dribbling, even if I say so myself. I don't look at the ball when I'm dribbling because…Read more …
