Visual Perceptual Skill testing In Sydney

Developmental vision information processing

DVIP (Developmental Vision Information Processing) assessment is a specialized test that evaluates how the brain interprets the visual information the eyes see. Conducted by behavioural optometrists, it tests critical skills like visual memory, spatial awareness, and tracking, commonly aiding children struggling with reading and learning.

20/20 vision isn't the whole story

Being able to read the eye chart is only one aspect of vision. Effective visual processing allows you to:

Interpret what you see accurately
Process visual information quickly
Store and recall information in visual memory
Coordinate vision with movement
Make decisions based on visual input

Signs That a DVIP Assessment May Help

Difficulty with Reading: Struggles with reading comprehension, frequent re-reading, skipping lines while reading, or avoids reading.

Letter or Number Reversals: Frequently confusing or reversing letters and numbers such as b/d, p/q, or 6/9, which can affect reading accuracy, spelling, writing, and confidence.

Poor coordination or ball skills: Difficulty judging distances, catching or throwing a ball, or coordinating movements that rely on accurate visual information.

Difficulty organising written work: Challenges with spacing, alignment, margins, and arranging work neatly on a page, making written tasks harder to complete and follow.

Poor spelling: Difficulty remembering and correctly sequencing letters within words, leading to frequent spelling mistakes despite practice.

Difficulty remembering visual information: Finding it challenging to recall letters, words, shapes, symbols, or visual patterns after seeing them.

Diagnosing Visual processing DYsfunction

A comprehensive eye exam by a qualified optometrist is essential for diagnosing DVIP disorders. Dr. Mandy Huynh will perform a detailed evaluation to assess your child's visual processing status and identify any underlying issues. The assessment may include:

Comprehensive Vision Tests: Investigation of eye health, vision, prescription needs, colour vision, and functional visual skills including eye tracking, focusing, eye teaming, and depth perception.
Visual Processing Tests: Evaluatation of key skills including visual discrimination, memory, spatial awareness, form recognition, sequential recall, figure-ground perception, directionality, visual-motor integration, visual-auditory integration, and motor coordination.

Areas that will be assessed

Visualization – The ability to form a mental image and manipulate it in one's mind. Important for reading comprehension and mental math.

Visual Memory – The ability to recall the visual characteristics of an object or symbol after it's no longer in view. Weakness here affects sight-word recognition and recalling letter/number shapes.

Visual Sequential Memory – The ability to recall objects, letters, or words in the order they appeared. A deficit can cause reversed reading of similar words, e.g. confusing "saw" and "was."

Visual Discrimination – The ability to notice differences between similar-looking objects, shapes, letters, or words, e.g. distinguishing "horse" from "house."

Form Constancy – The ability to recognize that a shape or letter is the same even when it's smaller, larger, rotated, or in a different font. A deficit can make it hard to recognize the same letter in different fonts or sizes, and can affect generalizing shapes across worksheets.

Visual Figure-Ground – The ability to pick out a specific shape, letter, or word from a busy or cluttered background. A deficit can show up as difficulty finding a word on a page, a specific line in a math problem, or an item in a cluttered desk or bag.

Visual Closure – The ability to identify a whole object or word when only part of it is visible. Important for speed reading and quick recognition in math.

Spatial Orientation – The ability to understand the direction an object is facing relative to oneself. A deficit can cause letter reversals (b/d/p/q) and number reversals (6/9).

Spatial Relations – The ability to judge the position of two or more objects relative to each other and to oneself. Important for problem-solving, higher-level math, and consistent spacing between words when writing.

Visual–Motor Integration – The ability to coordinate visual input with motor output. Crucial for handwriting accuracy, efficiency, and legibility.

Does your child show any of the symptoms above?

If you notice these symptoms in your child, a 1.5 hour assessment with our behavioural optometrist is recommended to assess visual perceptual skills.

A visual perceptual consult is $365 out of pocket and comes with a report for other medical professions and teachers.

Don’t let your child's visual skills hold them back. Take control of their visual potential by scheduling an appointment with Dr. Mandy Huynh. We are here to help them achieve clearer, more comfortable vision. Book Online Here, or call us at (02) 8542 2909.
