What this symptom means clinically

Glaucoma refers to elevated intraocular pressure caused by imbalance between aqueous humor production and outflow, potentially damaging the optic nerve and internal eye structures. Clinically, it should be interpreted as a sign that may arise from several mechanisms rather than a diagnosis by itself. Careful observation of onset, duration, severity, associated behavior, and objective changes helps a veterinarian determine the likely body system involved and the urgency of evaluation.

🐱 In cats

In cats, Glaucoma may be associated with secondary causes such as intraocular inflammation or lens problems commonly affect aqueous flow. Because cats often hide discomfort, small changes in appetite, grooming, posture, litter box use, or activity can be clinically important.

🐶 In dogs

In dogs, Glaucoma may be associated with drainage-angle anatomy or secondary disease can predispose some dogs to pressure elevation. Breed, body size, activity level, and recent exposure or trauma can influence how obvious the sign appears.

Clinical signs you can observe

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

Record the first date and exact time when Glaucoma was noticed
Record frequency, duration, and whether Glaucoma is persistent or intermittent
Take clear photos or short videos from the same angle and note the time recorded
Record appetite, water intake, activity level, and any behavior change
Record visible changes in color, swelling, discharge, pain response, posture, or function as relevant
Record any trigger, recent diet change, trauma, medication, environment change, or exposure history
Measure and record relevant objective values when safe, such as temperature, respiratory rate, heart rate, body weight, size, or amount
