Breakdown of brain’s visual networks linked to mental illness

Breakdown of brain’s visual networks linked to mental illness

Article by Kara Manke, Duke University: https://medicalxpress.com/news/2018-05-breakdown-brain-visual-networks-linked.html?fbclid=IwAR0ey_T1AbJbqXAjhQQH73xYl6qvQjKMhscGksKVme9IsFHER_RslPp0phE A follow up to the previous post. These research findings are not at all surprising to me. I would also like to add that it is highly likely that these results do not only pertain to a breakdown of those circuits but also to an incomplete initial development of these circuits (because of strabismus or amblyopia for instance). "People who reported a greater number of or more intense psychiatric symptoms were assigned a higher p-factor score. All participants who were diagnosed with mental disorders were referred for treatment. In a study published…Read more …
Why are sounds more “real” and understandable to me than visuals?

Why are sounds more “real” and understandable to me than visuals?

Michael Lievens: "When you learn a second language at a later age, it is "stored" in a different brain region than your native language, and more detached from your emotional centers. As Nelson Mandela once said upon learning Afrikaans: "If you speak to a man in a language he understands, you will reach his head. If you speak to him in HIS language, you will reach his heart." I'm having a similar experience using my various senses. When I listen to a text, it is directly absorbed by my intellect. But when I try to…Read more …
TESTIMONIAL: Teagen D. (38) achieves visual fusion for the first time in her life. Amazing!

TESTIMONIAL: Teagen D. (38) achieves visual fusion for the first time in her life. Amazing!

Teagen D. (38) is a game producer and programmer living in Seattle. As a child one of her eyes was patched and she had two strabismus surgeries at the ages of 1 and 12. She thinks the patching wasn't very effective and the surgeries did more harm than good. "My pediatric ophthalmologist was a classic anti-Vision Therapy doctor. He told me I'd never improve my condition." In 2001, as a college student, Teagen started Vision Therapy at the age of 21. Over the last 17 years she has done 5 rounds of VT under…Read more …
TESTIMONIAL: Logan Oostdyk (21) on getting into “the space” and seeing its depth

TESTIMONIAL: Logan Oostdyk (21) on getting into “the space” and seeing its depth

Logan Oostdyk is a 21 year old student living in Michigan. He developed esotropic strabismus at the age of five and his left eye consequently turned amblyopic or "lazy". Thankfully he never had eye muscle surgery and started Optometric Vision Therapy in April, 2017. Parallel to his own Vision Therapy and own visual experiences, he is pursuing his interest in vision development and currently works part time as a Vision Therapist at Dr. Angela Sanders' (OD) office in MI. After eight months of personal Vision Therapy, these are some of his thoughts and observations.  ...... "Some of…Read more …
The Crowding Effect: Importance in reading readiness and its assessment

The Crowding Effect: Importance in reading readiness and its assessment

What is the crowding effect? People with amblyopia experience the crowding effect, which is described as difficulty reading a letter when it is surrounded by other letters or contours. For this reason, when testing visual acuity in amblyopes, you may measure a better visual acuity using isolated letters than if you use a single line or the entire chart. When reading a row of letters, amblyopes can usually also read the first and last letters more easily than the middle letters. The crowding effect is more pronounced in strabismic amblyopes than anisometropic amblyopes.…Read more …
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 …
E-book version of ‘Applied Concepts in Vision Therapy’

E-book version of ‘Applied Concepts in Vision Therapy’

As you might have noticed lately, I've been studying and sharing many interesting passages from the book 'Applied Concepts in Vision Therapy' by Leonard Press. It's pretty darn awesome but it took me a long time before I was able to start reading it. I ordered the physical copy from OEPF years ago and only recently found a way to turn a book into an audio file: I scanned the book, had a program run text recognition on the images and then turned the text into an audio file. This cumbersome process allowed…Read more …
FAQ: Figuring out a prognosis for functional strabismus recovery

FAQ: Figuring out a prognosis for functional strabismus recovery

Having read the strabismus chapter of "Applied Concepts in VT", I've found many encouraging but also discouraging quotes. Keep in mind that I mostly read this chapter with my own case in mind. This means that factors pertaining to my own case stand out more to me. Factors that might be immensely important to other patients' cases and mentioned in the chapter are not necessarily mentioned in my list. This table of probability allows one to calculate the odds of functional recovery of a strabismic based on his or her specific characteristics. It's…Read more …

FAQ: Example of a Comprehensive Visual Processing Evaluation intake report (PDF)

Below you will find the intake report of a 58 yo female patient suffering from Convergence Insufficiency and various other visual deficiencies. This report was compiled based on two separate one hour testing sessions. The two sessions were done on two different days in order not to have fatigue skew the results.  Page 1 gives a statistical overview of how the patient did in terms of population percentile or age equivalent and whether or not this performance was adequate for healthy every day visual function. Page 2 to 5 explain what the various…Read more …
Passing the motorcycle road test

Passing the motorcycle road test

On the sixth of April I passed my final motorcycle exam: the road exam.  As far as visual learning goes, the motorcycle experience was very interesting in analyzing the flaws in how I learn. It reaffirmed some of the bottle necks in my visual process. To work around oculo-motor limitations and the lack of stereovision, I largely rely on cognitive adaptations grounded in experience and extra vigilance. Regardless of my limited visual skills and stamina, I maximally used my current visual skills in order to accomplish the task.  Basically I learned to work around…Read more …
