When you’re studying for a big exam—whether that’s a final or the NBEO—sometimes you just want to step away from the dry presentation of disease found in your textbook and take a more visual approach. That’s why we’ve partnered with optometry student Tyler Mathenia to give you this downloadable clinical study guide on binocular vision and BV disorders!

Binocular vision seems simple on the surface—it’s just vergences, right?—but there are multiple methods of assessing deviations and accommodative disorders. This study guide breaks those down in an easy-to-read format with examples, plus space for your own notes! Download the guide for quick reference, or for your own #studyspo.

Here’s what’s included:

This guide reviews need-to-know information for anyone studying binocular vision and accommodative disorders, including:

  • Types of deviations
  • Common patient complaints
  • Non-strabismic binocular vision and accommodative disorders
  • Tests for deviation assessment

And more—including treatment options!

What are common binocular vision disorders?

Binocular vision refers to the motor coordination of the two eyes to align the foveas from each eye on an object. This allows for the fusion of sensory information from the eyes to be sent to the brain.

The most common patient complaints about binocular vision disorders are cosmesis and asthenopia (the term for non-specific symptoms including but not limited to eye strain, blurred vision, and diplopia).

Non-strabismic binocular vision disorders are categorized by a combination of the following: divergence or convergence, and insufficiency or excess. Accommodative disorders are categorized by insufficiency, excess, or infacility.

How do optometrists diagnose and treat strabismus and other binocular vision disorders?

For strabismus patients, a detailed case history—including both time and type of onset—is crucial for the prognosis of the condition.

The tests to assess deviations focus on criteria like:

  • Magnitude of deviation
  • Amplitude of deviation
  • Response accuracy
  • Facility of accommodation flexibility

Many of these assessments should be done to test vision at both near and distance.

Once testing is complete, treatment options are varied! They include:

  • Optical correction: prism and plus add at near
  • Vision therapy
  • Surgery

I’m Tyler Mathenia, an Optometry Student from Midwestern University, Chicago College of Optometry Class of 2021.

My two favorite words are “grit” and “adventure” and my friends would describe me as empathetic and passionate. I’m married to my college sweetheart, Megan.
