What causes a guinea pig's watery, red eye? How can I treat it?

This problem could be due to a corneal ulcer and secondary conjunctivitis, probably secondary to a trauma or infection. A check up would be needed to confirm this clinical suspicion and as appropriate treatment would include antibiotics and anti-inflammatory eye drops.

I am so sorry that you are having problems with both of your guinea pigs. Because your other guinea pig had signs of a respiratory (nose, windpipe, and lungs) issue, I would recommend having Peaches evaluated by a veterinarian. Many times, respiratory diseases can be contagious, and may present with abnormalities of the eyes (the eyes and nose are connected, so bacteria and other organisms can spread between them!). From the pictures, the changes appear to be mild right now, which is great as you have caught it early! Other things that can cause both watering of the eyes and respiratory problems is bedding in the cage. Shavings made of pine or cedar can be irritating to both the eyes and the respiratory system, and can result in sneezing and watering of the eyes. Excessively dusty bedding can do the same things. If these are present, I would recommend changing those out and looking for improvement. Your veterinarian will be able to look closely at Peaches' eyes, and take a close listen to her lungs to make sure she is not also having respiratory signs.

Sorry to see this has happened to poor Ellie. She requires immediate veterinary attention as this eye is badly infected and will be very painful. I suspect she has developed a bad corneal ulcer or there has been trauma to the eye. She needs to assessed by a veterinarian and appropriate treatment given. They may be unable to save the eye.

Thanks for reaching out about your guinea pig. Eyes infections, corneal abrasions (from hay, other trauma), dental disease and other ocular problems are common and should be assessed by a veterinarian, before they progress. The redness is a clinical sign of inflammation or bleeding. Good luck.

It sounds as Uzi is suffering from an eye infection, it is relatively common in guinea pigs. you will need to take him to the vet the first chance you get, the vet will check the eyes to make sure there is no damage or foreign body in it, if it is indeed a simple eye infection your vet will prescribe an antibiotic eye drops that will probably solve the problem in no time.

Thank you for submitting your question regarding Pebbles. I recommend that he sees his veterinarian as he may have an eye infection. The veterinarian will use an ophthalmic scope to evaluate the eyes. He will likely need an eye drop or ointment. Is he sneezing or having any other signs of disease? If so, he could have an upper respiratory tract infection and may need an antibiotic. I hope this information helps!

Mochi's eye does look like there is infection. Have her examined by your veterinarian for confirmation. She will likely need antibiotics if infection is diagnosed. Use a warm washcloth to gently clean the eye, change bedding frequently to minimize irritating dust. If you are using pine or cedar shavings, immediately clean the cage and use aspen shavings or recycled paper bedding. The cedar can be irritating and may cause liver disease.
