How Horses Really See: Motion, Color, Depth and the Diseases Owners Miss Part 2 — Dear Horse World, it's Dr. Dennis Brooks

In Part 2 with Dr. Dennis Brooks, we step fully into the world as horses see it. This episode unpacks the five emerging immune mediated eye diseases he is treating around the world, why one of them is more alarming than moon blindness, and how tiny changes in the cornea can trigger sudden behavior shifts.

We explore how horses process color, motion, and depth, why their optic nerves move information faster than ours, and how they can perform at an elite level with one eye or even with no vision. We also bridge ophthalmology with neuroscience to understand how the equine brain reads emotion, remembers experiences, and navigates the world with extraordinary sensitivity.

In this episode, you will learn:

• The five types of immune mediated keratitis and the one specialists worry most about
• How to spot early signs of cloudiness, floaters, or subtle vision changes
• What colors horses truly see and how this affects training and jump design
• Why horses detect motion in low light far better than humans
• How elite horses perform with limited or no vision
• How the equine brain processes emotion, memory, and spatial cues
• When sudden behavior changes may originate in the eye and what to do next
