19. Strabismus and Convergence Need Careful Language
The parent's report says that the clinical report contains cover/uncover results, a diagnosis of strabismus, and a recommendation for surgery, but apparently does not mention convergence insufficiency.
Here we should make an important distinction.
A diagnosis of strabismus severe enough to lead to a surgical recommendation does not by itself allow us to substitute the separate clinical diagnosis “convergence insufficiency.”
But from the Turner Vision standpoint, significant strabismus makes the child's binocular and convergence organization highly relevant to functional assessment.
The medical report and Turner assessment are answering different questions.
The medical report may establish:
ocular alignment findings → strabismus → medical/surgical management
Turner Vision is additionally asking:
How are the two eyes organizing functionally acros...

10. The Diamond Scale as a Convergence Field
This is where your existing Diamond Scale becomes extremely important.
The main points and facets crossed during the Diamond Scale shouldn't only provide information about where vision is available.
They can also provide locations at which convergence should remain available.
Instead of testing convergence only along a central near/far line, you can examine it throughout the Diamond.
That potentially gives us a functional convergence map.
Â
11. Center Convergence
At the center:Â Midline convergence
Can the eyes organize together toward the shared visual target?
Can that organization be maintained?
Does one eye alter its relationship?
Does the convergence appear stable?
This establishes the central relationship.
But then the target has to move.

As the Diamond Scale moves through left ...

Convergence Is a Developmental Organization, Not Just Bringing the Eyes to Center
WHAT I'VE BEEN WORKING ON -
Purpose
To establish convergence as a whole developmental organization involving vision, fine motor skills, gross motor skills, spatial organization, midline development, and movement.
In Turner Vision, convergence is not adequately demonstrated by bringing an object toward the nose and observing whether the eyes come inward.
That demonstrates only one location and one condition.
Functional convergence must become available throughout visual space and through developmental movement.
Â
1. What Turner Means by Convergence
Convergence includes multiple interrelated organizations:
Visual convergence
The two eyes organize toward a shared visual relationship.
Fine-motor convergence
The hands organize toward one another and toward center.
Gross-motor convergence
The larger body organization brings the extremities and body relationsh...
When to Evaluate Your Child's Vision and Development

 Vision Needs to Be Evaluated: Four Times Parents Should Look Deeper
When a child has developmental, movement, communication, or sensory concerns, vision should not be treated as a separate issue that is considered only when a child says, “I can't see.”
Young children may not know that they are seeing differently. Nonverbal children may not be able to tell us what they see at all. And a child's ability to recognize or respond to something does not necessarily tell us how well their visual system is functioning.
Vision plays an important role in how a child organizes movement, responds to their environment, develops spatial relationships, and learns to interact with the world around them.
Here are four situations in which I believe a child's vision needs careful evaluation.
1. Your Child Has a Neuromuscular Condition or Diagnosis
The eyes are muscles, too.
When a child has a condition affecting neuromuscular development, we should not examine the body while treating the eyes as t...
Movement Lesson: Vision and Development

Vision + Development Movement Lesson
Â
Developmental Vision → Functional Organization → Movement Integration
Â
Purpose
To show that visual development is not an isolated sensory achievement and is not adequately represented by whether a child can “see.”
Turner Vision examines how vision becomes functionally organized through development, how that organization participates in developmental movement, and how interruption or stress within visual organization can affect the child’s ability to progress through subsequent developmental functions.
The purpose is not to create another milestone checklist.
The purpose is to understand:
What should be organizing → what is actually organizing → where is the stress → what function is being affected → what needs attention.

Before interpreting developmental visual behavior, establish whether the child has adequate visual access.

...Are there Apps for CVI?
Aug 18, 2026
Working with a tablet can seem like the perfect idea for your child to get some visual interaction.
This is the time you are working with YOUR CHILD. Visual stimuli doesn't necessarily mean you are working on visual functions.
Here are some things to avoid or supervise:
Â
1- Does your child have binocular vision? Do both eyes work together? If the answer is no or sometimes, then you want to limit tablet time. This close vision, with no depth perception, does not bring the eyes into synchronized vision.
Â
Â
2- Does your child have weak convergence? If so, then they also have weak binocular vision. It's impossible to work with depth perception or convergence with the tablet. If anything, it can create hyper-convergence and tunnel vision. Racing games are notorious for that. Other apps show no depth perception - making the app easier but not what's best for your child. You can see this in Peek-a-Boo Barn. It's very flat and not visually complex. It doesn't work ...
Coxa Valga and Incomplete Ischiums

How Coxa Valga and Incomplete Ischiums Can Impact Development in Toddlers
Coxa valga and incomplete ischiums are two relatively rare skeletal conditions that can affect toddlers' development,primarily impacting motor skills, posture, and potentially long-term growth. Here's a breakdown of their individual and combined potential consequences:
Â
Â
Coxa Valga:
-
Definition:Â Abnormal widening of the angle between the femur (thigh bone) and the acetabulum (socket in the pelvis where the femur joins).
-
Impact on Development:Crawling and Walking:Â transitioning skills are key to all developmental milestones. Straight legs cause difficulties of getting in and out of positions, especially from off the floor. Your child's gait, difficulty with balance and coordination due to instability in the hip joint not supporting the pelvis and its movements.

Beyond Sensory Regulation: Our Subsenses Hold the Key
Instead of simply focusing on regulating overwhelming sensory input, we delve deeper into the intricate workings of the human body through our unique framework of subsenses:
-
Balance + Counterbalance = ACTION:Â This subsense governs our ability to move purposefully and interact with the world. When dysregulated, it can manifest as clumsiness, difficulty with coordination, and an aversion to movement.
-
Succumb + Oppose = GRAVITY:Â This subsense helps us understand our relationship with gravity, crucial for balance and spatial awareness. Dysregula...
Baby's First Milestone
Aug 11, 2026
You think it's 'Lying Down' but it's their Absolute Horizon
For a parent to assume our development when it can be attained and manipulated by oneself and others through a cognitive process without knowing where that being has originated through movements contained in ones birth and development. When a newborn baby is in the process of a typical natural delivery and starts the crown, the baby has rotated in position for the head to mold and elongate out of the vaginal canal. After the presentation of the head, the rotation will continue to allow soft tissue to initiate functions as each shoulder to exit the womb separately.
Â
Â
This rotation continues to allow lung expansion through cavitation to introduce oxygenation function as the body continues to leave the mother’s system. This rotation initiates the newborn’s system mechanics to have a complete organization of its horizon. The body’s inability for external and internal experience of these and many other functions ...
Why Does My Child Lose Their Balance?
Aug 08, 2026
Â
Balance is rarely the first problem.
It’s usually the result of something that happened earlier in development.
Â
Instead of asking, “Why can’t my child balance?”
Â
Â
Start by asking:
Â
Can they use their vision while they move?* Looking near and far
* Crossing visual midlines
* Using peripheral vision
* Looking where they are going
Â
Can they transition smoothly?* Sitting to standing
* Standing to squatting
* Getting on and off the floor
* Recovering from small losses of balance
Â
Â
Can they adapt to change?* Different surfaces
* Stepping over obstacles
* Turning while walking
* Stopping and starting
Â
Â
Balance isn’t just standing still. Balance is the ability to stay organized while your environment changes. Sometimes the answer isn’t strengthening balance. It’s the stage of development that needs support first.
