Plain-English summary
A 4-year-old male Chihuahua lost vision in his left eye after a dental procedure where a local anesthetic was accidentally injected into the eye. The vet found some bleeding and cloudiness in the eye but no damage to the lens or retina. To treat the issue, the dog was given a pain reliever and an antibiotic. Fortunately, just one week later, the dog's vision returned to normal, and he was able to respond to visual cues again.

Abstract
CASE DESCRIPTION: A 4-year-old castrated male Chihuahua was evaluated because of unilateral vision loss following extraoral administration of a caudal maxillary nerve block during a dental procedure. CLINICAL FINDINGS: The menace response was absent in the left eye, but the pupillary light reflex was intact. Vitreal hemorrhages and opacities were present on ophthalmic examination of the left eye. Ultrasonographic findings were supportive of the clinical findings. The posterior lens capsule and retina appeared to be undisturbed. TREATMENT AND OUTCOME: Treatment consisted of administration of carprofen and prophylactic administration of amoxicillin-clavulanate. Vision was clinically normal with an intact menace response 1 week later. CLINICAL RELEVANCE: Findings indicated that intravitreal injection of the local anesthetic agent should be considered as a potential complication when performing nerve blocks prior to dental procedures in dogs.
