Ocular motor dysfunction refers to a group of disorders that affect the coordination and control of eye movements. The eyes have six extraocular muscles, and these muscles, coordinated by the brainstem and cranial nerves, allow the eyes to move in various directions. When there is dysfunction in this system, it can result in the inability to move the eyes accurately and efficiently.

Types of Ocular Motor Dysfunctions

  1. Saccadic Dysfunction:

    • Saccades are rapid, jumping eye movements that change the point of fixation, such as when reading.

    • Dysfunction may result in difficulty moving eyes accurately from word to word while reading, causing skipping of words or lines.

  2. Pursuit Dysfunction:

    • Pursuits are smooth, tracking eye movements to follow a moving object.

    • Dysfunction may lead to the inability to smoothly track moving objects, causing overshooting or undershooting.

  3. Gaze Stability (Fixation) Dysfunction:

    • It involves maintaining visual fixation on an object, crucial for reading or recognizing faces.

    • Dysfunction may lead to difficulty maintaining focus on an object.

RightEye Reading Tracker

  1. Calibration:

    • At the start, the person follows a moving dot with their eyes. This helps the system understand how their eyes move.

  2. Reading:

    • The person reads a piece of text on the screen. The system watches how their eyes move as they read.

  3. Data Collection:

    • The system collects data on where the person looks and how fast their eyes move between words.

  4. Results:

    • After reading, the system creates a report. It shows where the person looked the most and how quickly they read.

poor tracking

1 in 4 children has an undetected vision problem that interferes with reading and learning, often misinterpreted as disinterest, dyslexia, or ADHD. Seeing the letters on the traditional static eye exam​ is only one of the necessary vision skills students require.

Vision & Learning Center uses the RightEye system to show parents HOW their child is tracking while reading and help them understand how these challenges are impacting their ability to comprehend what they are reading. 

  • Record and illustrate possible deficiencies in reading and binocular vision issues

  • Understand a student’s eye movements while they are reading

  • Quantify reading comprehension and compare reading metrics against similar grade-level peers
