Guinea Pigs/Guinea pig eye

Hello, do you know what this might be on my guinea pigs eye? I am worried that i have made it worse by gently wiping it because i wasn't sure if it was attached to his eye. It does seem to be attached though, more to the inside of his eye. It looks more red now than yesterday but i am sure that he has had it a while.
I was thinking it may be one of these on this website but i can't identify them:

I have some images i took of his eye.

Any help will be great.

Thank you for your time.

I have to be honest with you and say I'm not certain what this is. I can tell you what it is NOT, and that's something we call pea eye or fatty eye. That is when the conjunctival tissues inside the lower lid protrude slightly as the lower lid droops.  It's much like a Bassett Hound has, and in dogs it's considered cute.

Here are two pictures of classic "pea eye."

This appears to be a blood vessel but why it's protruding is the issue. It does not look to me like an injury to the actual globe of the eye, but rather the tissue inside the eye.

If it were my pig I would do nothing, otherwise you may worsen it. It doesn't appear to be irritating the eyeball itself so it is very likely harmless and is just a cosmetic issue.  If it were an injury I would expect to see the eyeball itself reddened and irritated, and this is not.

As is sometimes the case, people in urgent need of information have a higher degree of expectation than those of us as experts are able to give. The experts on this site do their best to give the most accurate and responsible answers possible. We ask that you remember that it is not our intention nor place to criticize the professional advice given by your veterinarian, nor is it appropriate for us to comment on the correctness of a diagnosis made by a licensed physician. Our knowledge is experience based. Although many years of breeding and showing cavies gives me a wealth of experience it cannot change the fact that we as experts are not veterinarians and therefore may occasionally have to reject questions that appear to be asking us to criticize advice given by the licensed professional. Having raised and exhibited cavies for many years I have extensive experience in cavy care and husbandry. I currently have an active breeding program for pedigreed show animals but do not encourage backyard breeding for inexperienced owners. Although I don't encourage breeding for fun I'm always happy to answer any questions from an owner who is in sincere need of help. Pet owners wanting to breed should understand that even experienced breeders have litter losses. The mortality rate is high in cavies. The chance for losing both sow and pups is always present, even with experience. Although this is a site for experts to assist owners, there is no expert in any field who has all the answers. The wisest thing a good expert can know is their limitations. Not having an answer does not diminish one's ability or knowledge. It simply shows that we recognize our limitations and operate within them.


Raised and shown cavies for many years, having aquired my first cavies in the early 1970's as pets. My caviary currently handles 65 + animals in two different breeds and several varieties. Having been in the health care industry as a licensed nurse for 35 years I have hands on experience with care and needs in both humans and cavies. Member of American Rabbit Breeders Association and American Cavy Breeders Association.

Awarded Lifetime Membership in of one of the oldest cavy clubs in the United States, on whose Board I served as Sec/Treas for six years and currently serving as President. Also editor/publisher of the club's quarterly newsletter. We are strong supporters of our youth exhibitors, most of whom are 4H members who are working on cavy projects. Through these projects they become good responsible citizens. We deal with all aspects of showing, breeding, caring for and sharing experiences in the fancy. The cavy fancy is not a new one but in some areas is still relatively unknown. Our goal is to inspire interest in high quality, responsible breeding to improve the species, not just the reproduction of guinea pigs. Our job is to educate owners to help them make the right decisions and choices in the care of their cavies.
