Tearing or Gunky Eyes…
Central Otago windy weather predisposes to blocked tear ducts.
The tear duct is the drainage portal from the eye to the nose. In many situations, but especially windy and dusty ones, the ducts can narrow or get fully blocked.
If your horse has tearing or gunky eyes, it is possible this duct could need flushing. The photo demonstrates how the tears drain into the nose (the green is a special dye used in eyes).
