What this symptom means clinically

Uveitis is inflammation of the uveal tract inside the eye, including the iris, ciliary body, and choroid. It disrupts the blood-ocular barrier, allowing plasma components and inflammatory cells to enter the anterior chamber or vitreous. This type of inflammation can cause changes in pupil response, anterior chamber cloudiness, aqueous flare, or changes in intraocular pressure, affecting light perception and visual function.

🐱 In cats

In cats, uveitis is often associated with systemic or infectious factors. Clinical signs and causes may be more varied and require detailed evaluation.

🐶 In dogs

In dogs, uveitis is often related to immune-mediated or systemic inflammation and may appear differently in one or both eyes.

Clinical signs you can observe

Check whether your pet shows any of the signs below. If several apply, seek veterinary care promptly.

Take front and side photos to compare the appearance and changes between both eyes
Compare and record left and right pupil size and response to light, including any obvious difference
Observe and record whether the ocular surface and conjunctiva are red or bloodshot
