Feline eyes are delicate and prone to various disorders, making ophthalmic care a key part of cat health. Common issues include conjunctivitis, corneal ulcers, uveitis, glaucoma, cataracts, and conditions linked to feline herpesvirus type 1 (FHV‑1) or taurine deficiency. Owners should watch for eye discharge, redness, cloudiness, squinting (blepharospasm), excessive tearing, or a protruding third eyelid—all signs that require veterinary attention. Early detection protects vision and reduces discomfort, as many eye problems progress quickly without treatment.
Conjunctivitis, or pink eye, is the most widespread feline eye problem. It causes inflammation of the conjunctiva, leading to redness, swelling, and discharge ranging from clear to thick and colored. FHV‑1 is a leading infectious cause, often triggered by stress. Bacterial infections, irritants, or allergies can also contribute. Vets typically diagnose with a physical exam and may prescribe antiviral or antibiotic eye drops, along with environmental stress reduction.
Corneal ulcers are painful injuries to the eye’s clear outer layer, often caused by scratches, fights, or FHV‑1. Symptoms include cloudiness, constant squinting, and increased tear production. Fluorescein staining helps identify ulcers; treatment includes topical medications to prevent infection and promote healing. Severe cases may need surgical intervention to avoid permanent damage.
Uveitis, inflammation of the eye’s middle layer, has many causes including infection, trauma, or immune disease. Signs include a cloudy anterior chamber, pupil constriction, and light sensitivity. Untreated uveitis raises risks of glaucoma and cataracts. Diagnosis involves intraocular pressure measurement and blood tests; treatment targets the underlying cause with anti-inflammatory drugs.
Glaucoma involves dangerously high eye pressure, causing pain, bulging, and rapid vision loss. It can result from uveitis, lens luxation, or other blockages. Emergency care with pressure-lowering medications or surgery is critical to save sight. Cataracts, a cloudy lens, reduce vision and may stem from aging, diabetes, or inflammation; advanced cases require surgical removal.
Nutrition also matters: taurine deficiency can lead to retinal degeneration, so complete commercial cat food is essential. Regular eye checks, gentle cleaning of discharge, and prompt vet visits for abnormal signs help maintain long-term ocular health. By learning to spot symptoms and seek timely care, owners can safeguard their cats’ vision and quality of life.
