What should I do if a rat's eye is swollen? - in detail
If a pet rat presents with a puffy or inflamed eye, begin by examining the surrounding area for signs of trauma, discharge, or foreign material. Gently separate the eyelids with a clean fingertip or cotton swab to check for debris; do not apply pressure to the globe. If a visible object is present, remove it with sterile tweezers only if it is easily accessible and you are confident in your technique. Otherwise, seek professional assistance immediately.
Next, assess the rat’s overall condition. Look for changes in appetite, activity level, or respiratory signs, which may indicate a systemic infection. Record the eye’s appearance: note whether swelling is unilateral or bilateral, the presence of redness, tearing, or crusting, and any alteration in pupil size. This information will aid the veterinarian in diagnosing the underlying cause.
Provide a clean, dry environment while awaiting veterinary care. Keep the cage free of bedding that could irritate the eye, and ensure the animal is not exposed to drafts or direct sunlight. Offer fresh water and food within easy reach to reduce stress. Do not administer over‑the‑counter eye drops or ointments without veterinary approval, as many products are toxic to rodents.
When consulting a veterinarian, be prepared to discuss:
- Duration of the swelling
- Recent injuries or fights with other rats
- Exposure to dust, bedding, or chemicals
- Any previous eye problems or illnesses
The clinician may perform a fluorescein stain test to detect corneal ulcers, prescribe antibiotic ointment or drops for bacterial infections, recommend anti‑inflammatory medication for non‑infectious swelling, or conduct a thorough ocular exam to rule out tumors or systemic disease.
Follow the treatment plan precisely. Apply any prescribed medication with a sterile applicator, typically two to four times daily, and monitor the eye for improvement. A reduction in swelling and discharge within 24–48 hours usually indicates a positive response. If symptoms persist, worsen, or the rat shows signs of pain (e.g., excessive blinking, pawing at the eye), return to the clinic promptly.
Preventative measures include maintaining low‑dust bedding, avoiding overcrowding, providing chewable enrichment to reduce aggression, and scheduling regular health checks. Early detection of ocular issues can prevent permanent damage and preserve the animal’s quality of life.
