Conjunctivitis

Sometimes referred to as “pink eye” or “red eye,” conjunctivitis is the inflammation of the eye's outermost layer. Frequently due to bacterial infections, there are two kinds of bacteria that are most commonly involved in conjunctivitis: Bordetella and Streptococcus. Although conjunctivitis is not a very serious condition in guinea pigs, its underlying cause needs to be identified and treated promptly to prevent any further complications.

Guinea pigs are very sensitive animals and are likely to develop allergic reactions to some antibiotic medications. Therefore, it is best to consult a veterinarian before attempting to administer any eye drops or ointments at home.

Symptoms

• Dripping, watery fluid from the eye
• Pus-filled discharge from the eye
• Swelling and inflammation of the eye
• Redness around the edge of the eyelids
• Sticky eyelids (from the dried up discharge)

Causes

Bacterial infections, such as Bordetella and Streptococcus, are a frequent cause for conjunctivitis in guinea pigs; upper respiratory tract infections can also lead to this condition.

Diagnosis

Other than observing the clinical symptoms displayed by the guinea pig, your veterinarian will confirm a diagnosis of conjunctivitis by examining its blood or pus discharge. This will also help identify the infectious agent responsible for the condition.
