What this symptom means clinically

Strabismus is deviation of the eye from normal alignment, usually involving extraocular muscles, cranial nerves III, IV, or VI, or orbital structures. Muscle imbalance, impaired nerve conduction, or an orbital space-occupying lesion can prevent both eyes from focusing together.

🐱 In cats

In cats, strabismus may be subtle; trauma, congenital abnormalities, and neurologic disease can all alter eye position.

🐶 In dogs

In dogs, skull and orbital anatomy can influence eye position, and trauma, local masses, or neurologic dysfunction are common considerations.

Clinical signs you can observe

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

Record the date, time, and context when strabismus was first noticed.
Measure or estimate the affected area or vital value when applicable, and write down the exact value and unit.
Take clear photos or short videos from the same angle and label the date and time.
Observe whether strabismus is intermittent, persistent, improving, or worsening, and record duration.
Record related behavior changes such as appetite, activity, grooming, pain response, or avoidance of touch.
Compare left and right sides or resting and activity states when relevant, and record asymmetry or changes.
