Background: Only a few horses acquire this condition, though as more ophthalmologists measure pressures in the equine eye, the diagnosis is being made more frequently.
Symptoms: Eyes are large and protrude, feel hard to the touch and are painful.
Diagnostics: Increase in the intraocular pressure.
Special Notes: The condition may be primary or secondary.
Principles for Supplementation: Antioxidants are very helpful, especially those with affinity for the ocular tissues.
