They are caused by trauma, detergent burns, and infections. Other eye conditions can cause corneal ulcers, such as entropion, distichia, corneal dystrophy, and keratoconjunctivitis sicca. [63] Florida keratopathy an eye condition characterized by the presence of multiple spots within both corneas. In the United States, it is found most commonly ...
Corneal ulcers in cats can be caused by trauma, detergent burns, infections, and other eye diseases. One common cause not seen in dogs is infection with feline herpesvirus 1 (FHV-1). FHV-1 causes ulceration by direct infection of the epithelial cells. Lesions appear as round or dendritic (branching) ulcers. FHV-1 also suppresses healing of the ...
Canine space infections may occur by spread of infection from the buccal space. [2] Signs and symptoms of a canine space abscess might include swelling that obliterates the nasolabial fold . If left untreated, infections of this space will eventually spontaneously drain via the medial or lateral canthus of the eye, as this is the path of least ...

Dogs also have a greater divergence of the eye axis than humans, enabling them to rotate their pupils farther in any direction. The divergence of the eye axis of dogs ranges from 12–25°, depending on the breed. [36] Experimentation has found that dogs can distinguish between complex visual images such as those of a cube or a prism.
