a painful and recurring eye inflammation that affects horses
What is "moon blindness"?
Moon blindness, also known as recurrent uveitis or equine recurrent uveitis (ERU), is a condition that mainly affects horses. It is characterized by recurrent inflammation of the uvea, which is the middle layer of the eye. This inflammation can cause symptoms such as redness, tearing, sensitivity to light, and cloudiness of the eye. Despite its name, moon blindness is not directly related to phases of the moon; rather, it is believed to have various causes, including infectious, autoimmune, and genetic factors. Moon blindness can lead to vision problems or even blindness if left untreated. Treatment typically involves anti-inflammatory medications and actions to reduce flare-ups and protect vision.
