Blind quiet eye is the loss of vision in one or both eyes without ocular vascular injection or other apparent signs of eye inflammation. This may occur due to abnormalities in retinal image detection, retinal focusing, optic nerve transmission, or simply the central nervous system's inability to interpret images correctly. Symptoms may include bumping into objects, tripping, falling, decreased or absent menace response, impaired visual placing responses. These symptoms become more exaggerated when the dog is outside at night.
