Which ocular sign is listed as a distemper sign?

• A. Uveitis
• B. Cataracts
• C. Retinal detachment
• D. Glaucoma

Answer: (A)

Uveitis is the ocular sign most closely associated with distemper because canine distemper virus commonly causes inflammation of the uveal tract (the iris, ciliary body, and choroid). This intraocular inflammation manifests as red eye, photophobia, and signs of anterior uveitis such as flare in the aqueous and sometimes hypopyon. While cataracts, retinal detachment, or glaucoma can occur in eye disease, they are not the classic or characteristic distemper signs, whereas uveitis is frequently listed as a distemper-related ocular finding.
