What Causes Watery Eyes in Guinea Pigs?

Guinea pig watery eyes are often caused by injury, upper respiratory infection, dental issues, dehydration, or diabetes.

Eye infections are typically caused by mycoplasma pulmonis in rodents and mice, and bordetella bronchiseptica in guinea pigs.

You do this by placing a meal inside the identical colored bowl and converting the order daily

Eventually, you’ll find if your guinea pig searches for the colored bowl with food in the cage.

Eye Color

Guinea pig eyes are available in an entire lot of hues.

Breeders detect these shades as darkish, dark with a ruby cast, and purple.

Dark eyes could also be additionally defined as brown, black, or blue.

Healthy eyes mirror purple during a robust light.

This is often mainly noticeable in ruby pigs, whose darkish-looking eyes have a said crimson forged to them, specifically substantial whilst photographed with a flash.

The guinea pigs within the highest row have crimson and ruby eyes respectively.

The attention at the top of the page belongs to the top proper guinea pig underneath and is likewise ruby.

The guinea pigs within the bottom row have dark eyes.

Eye Discharge

Natural Eye Cleaning Fluid

Normal guinea pigs excrete a milky white liquid that lubricates their eyes and helps clean their faces.

After the eyes fill up with the white fluid, the guinea pig will then take their front paws and make washing motions.

This might additionally show up numerous instances consistent with day albeit you’ll by no means even remember.

VC Richardson describes a “milky ocular discharge” as “an ordinary fluid which is released from the attention to help with the grooming procedure.”

What Causes Abnormal Eyes in Guinea Pigs?

These signs and symptoms warrant an examination by a skilled veterinarian.

If your guinea pig’s eyes are crusty, watery, cloudy, receding, or protruding, or you’ve noticed a corneal ulcer, it can imply many things.

All those conditions of the eyes could mean there’s an upper respiratory tract infection, injury, abscess, tooth problem, dehydration/illness, cataracts, or diabetes.

Respiratory infections are often handled with antibiotics.

Read the damaging medications list before you contact a vet.

If a respiratory tract infection is suspected, then see a vet immediately.

What Are the Reasons for Watery Eyes in Guinea Pigs?

As already depicted above, it’s majorly caused by sickness.

There are numerous causes with a few potential reasons outlined below.

The sole eye-related manifestation of watery eyes is often connected to a regular cold, injury, or a stopped tear channel.

Another reason could be as a result of an injury.

On the off chance that you simply notice different side effects, an excursion to the vet is vital.

You need to likewise watch out for wheezing and different indications of the regular virus.

This additionally requires veterinary consideration.


A cloudy eye is often the result of an injury.

Abrasions, cuts, or punctures to the guinea pig’s eyes can come from coincidence, hay pokes or fighting.

Simply examine the eye closely, specifically around the rims.

Sometimes a piece of hay will show itself up at the rear of the eye and if it’s partially visible could also be pulled out with the help of tweezers.

If the eye shows symptoms of abrasion or clouds over in any way, or appears red inside the white area, or appears to be swollen or sinking or squinting – get your guinea pig to a skilled veterinarian.

Treat eye injuries promptly to prevent eye loss.

Plugged Lacrimal Duct

When the eyes are protruding, this can either suggest an abscess, elongated roots, or a different problem.

An x-ray can easily help diagnose those conditions.

Conjunctivitis, foreign items stuck behind the attention, dry eye, corneal ulcer, and tumors can also be the reason behind a swollen eye.

Oftentimes, eye infections or harm will cause preferred cloudiness of the entire eye.

Watery guinea pig’s eyes are often the result of a plugged lacrimal duct.

So what will the vet do when you visit him?

A vet will check the eye for signs and symptoms of injury or disorder.

He/she may additionally flush the eye and stain it to look for abrasions or ulceration then prescribe eye drops like Chloralean or Gentocin.

If the eye appears dry, the vet also can perform a tear test or send a pattern of the fluid to the lab for evaluation.

Medications such as Chloralean can clear up a corneal ulcer directly.

Application of an ophthalmic triple antibiotic eye ointment 2 or 3 instances every day may assist reduce redness.

Veterinary ophthalmologists can diagnose and affect hard eye issues.

Don’t delay seeking veterinary treatment.

Eye problems may result in permanent damage or eye loss if not treated.


Allergies are extremely uncommon in guinea pigs.

Do not make the error of diagnosing an eye discharge as an “allergic reaction”.

Instead, see a vet as your pet is counting on you.


A cataract is an opacity of the lens of the eyes.

Cataracts are often either inherited or the top results of disorder or age.

Older animals often experience a gradual clouding of their eyes leading to reduced sight.

Quick onset is pronounced to arise during a few guinea pigs with diabetes.

Congenital Cataracts

Cataracts are present within the young of a couple of strains and may develop in early adulthood in related animals.

Breeding from these lines is discouraged.

Some other young guinea pigs are often born with partial cataracts.

These animals seem to have the ability to see effectively.


Entropion is a condition that affects the eyes.

In this case, the eyelids, most especially that of the lower lid are being turned inward.

This causes the eyelashes of the guinea pig to rub against the eyeball causing discomfort.

The eyes can boot flip whitish white and broaden membrane ulceration.

Teddies, Rexes, and Texels breeds tend to be bigger in peril of entropion than different breeds.

In most instances, guinea pigs outgrow this condition in a few weeks.

The infection might even be mitigated by the method of applying sterile eye lotion together with various eye infection ointments for the length of the day.

Eye infection is out there and available at the foremost pharmacies.

You can purchase eye drops and ointments and also procure in-tuned lens merchandise.

Ophthalmic BNP is that eye product that can be used 3 or 4 times daily until there’s an improvement in the yes.

Some puppy homeowners try to remove the lashes out of the eyes when applying this ointment.

Entropion is sometimes genetic.

Depending upon the degree of problem, BNP will and can be administered.

Artificial tear ointment is something that can be applied to decrease membrane abrasion.

You can do this for a week and observe for any improvements.

You can also give this for a week first and then make use of a steroid ophthalmic especially for a guinea pig that has bilateral entropion.

It could also be a painful circumstance, thus pain meds have to be compelled to be taken into thought if it’s going to take a range of weeks to surgery.

It’s tough, though, as you won’t have to be compelled to give NSAIDs.

Sometimes an area anesthetic instruction (proparacaine) will assist.

There are varied faculties of notion on this one.

Some vets can “tack” the eyelids when they are young to prevent having to do the overall surgery later.

It should be done at the same time as they are little.

Some wait and do the complete surgery later if indicated.


Guinea pigs seem to possess dangerous visual modalities, to begin with.

According to biological science, some guinea pigs are blind because of age or injury.

Simply provide your ingenious and discerning impaired pig with familiar surroundings so he/she can find food, water, and fodder effortlessly.

What Are Fatty Eyes Or Pea Eyes in Guinea Pigs?

Pea Eye

Pea eye (or fatty eye) is a permanent protrusion of the mucosa sac, thought to be genetic.

Pea eye and fatty eye are oftentimes classified together by mistreatment vets as mucosa swelling.

If they are meddling with vision, these mucosa protrusions might even be eliminated by mistreatment optical devices.

Guinea pigs with pea eyes normally don’t appear to be uncomfortable and remedy is usually not necessary.

Red Eye

Red-eye usually shows up beneath strain or occurs in the presence of associate degree troubles like smoke.

Fluid Retention and Pea Eye

In some guinea pigs, pea eyes are usually caused or irritated by fluid retention.

Not all guinea pigs with heart issues and pea eye show changes whereas the employment of furosemide by one owner discovered that the pea eye is perpetually found in her pig with a heart condition (coronary heart disorder showed at post-mortem) became more serious.

The theory behind that is that in some pigs, pea eye is usually borne because of fluid build-up because of negative flow.

Inflamed Conjunctiva: How To Treat Inflamed Conjunctiva in Guinea Pigs?

A guinea pig with an infected mucous membrane became treated with nonsteroidal anti-inflammatory, a medicine drop, then Garamycin.

The vet behind the treatment reasoned that aside from decreasing the inflammation, the Garamycin would further attack the infection and treat it.

She reasoned that antibiotic drops alone did not seem powerful.

The anti-inflammatory/antibiotic combination labored well and cured the hassle for about3 or four months, till it finally overcame it.

“Cherry Eye”

“Cherry eye” in many animals usually refers to an organ that’s close to the lowest of the protective fold.

It’s usually purple in color instead of the regular white mucous membrane color.

A guinea pig doesn’t have a third palpebra, however, it has a lacrimal (tear-producing) organ made of lymphatic tissue.

It’s this organ that becomes infected and/or inflamed in the cherry eye and prolapses.

Cherry eyes in piggies when taken into consideration are usually uncomfortable, particularly, once things are further extreme and disturb vision.

In an analysis, the pea eye is mostly not painful or uncomfortable.

Cavies do have many lacrimal glands inside the perimeter of the orbit.

“Cherry Eye” can simply occur inside a very cheap “inside” nook of the eyes once you concentrate on that.

Ordinarily, pea eye is found inside the corners of eyes as nicely and may result in subscleral fats within the place, however, researchers square measure still find several viable things for pea eye.


Microphthalmia is a congenital condition in which eyesight is both very small or non-existent, rendering the guinea pig blind.

According to VC Richardson, it’s usually the result of breeding a roan X roan or dalmatian X dalmatian.

These white guinea pigs are referred to as “lethal”.

They’ll additionally have problems with the digestive system and therefore the animal could also be missing one or extra teeth.

During a roan X roan or dalmatian X dalmatian mating, there’s a 1 in 4 probability of breeding a lethal.

Responsible breeders will never deliberately mate these breeds as severely affected guinea pigs will die.

Lethals are often affectionate pets.

They require greater hospital treatment and might require hand feeding.

Lethals tend to remain shorter lives, depending on every pig’s unique genetic troubles.

Every roan pig has one reproduction of the roan model of the gene, and one copy of the everyday version.

Since it’s random which copy of the gene they bypass on to each baby, there is a 25% hazard of getting roan from mother and dad-this makes a “lethal”.

The everyday version of the gene is significant for the prenatal development of nerves, coat shades, and enamel.

These pigs can die before delivery, shortly after delivery, at weaning (if not well identified and handled), or as adults.

Usually, lethal have shorter lives than everyday pigs.
