Hamster Eye Infection

Conjunctivitis is an irritation or inflammation of the conjunctiva, which is the soft tissue lining the inside of the eyelids and the white portion of the eyes. 

It can be caused by: 

  • Bacterial infections: Bacteria like Staphylococcus and Streptococcus can infect the conjunctiva, the membrane lining the eyelids and eyeball.
  • Viral infections: Viruses like the adenovirus and calicivirus can cause conjunctivitis in hamsters.
  • Allergies: Dust, mites, or bedding materials can trigger allergic reactions in some hamsters, leading to eye irritation and inflammation.
  • Foreign bodies: Dust, sawdust, or even a loose thread from bedding can get into a hamster’s eye, causing irritation and infection.
  • Dental problems: Overgrown teeth or an abscess in the mouth can put pressure on the tear duct, causing eye discharge and inflammation.

Symptoms of Conjunctivitis in hamsters include: 

  • swelling of the eye or area
  • presence of pus (green or yellow)
  • cloudy eyes, sticky eyes (hamsters unable to open their eyes properly)
  • puffy eyes, and redness around the eye
  • crusting around the eyes

 If you notice any of these signs in your hamster, it is important to take them to the vet as soon as possible for appropriate treatment, which may include antibiotics.

Remove any excess food or waste to ensure it doesn’t collect near their living area.

Other Hamster Eye Issues 

Proptosis/Exophthalmos in Hamsters

Proptosis, also known as exophthalmos, refers to the protrusion of the eye from its normal position in the orbit.

Hamsters develop exophthalmos in relation to a condition called sialodacryoadenitis. Sialodacryoadenitis can lead to keratoconjunctivitis sicca and subsequent exophthalmos and proptosis in hamsters.

In general, proptosis/exophthalmos in animals, including hamsters, is often caused by: 

  • traumatic events such as blunt force injury
  • fights with other animals
  • excessive physical restraint 

During the trauma, the globe (the eyeball) becomes displaced from the orbit, and the eyelids may become entrapped behind the globe, preventing its return to its normal position.

To provide appropriate care for a hamster with proptosis/exophthalmos, it is crucial to seek veterinary attention immediately. 

The veterinarian will perform a thorough examination to confirm the diagnosis based on the clinical appearance of the eye, including its protrusion and the inability of the eyelids to blink over the cornea. 

Treatment options may include globe replacement surgery (GRS), which involves returning the displaced eye to its normal position in the orbit. 

Postoperative therapy typically includes medications such as antibiotics, anti-inflammatories, and analgesics.

Cataracts in Hamsters

Cataracts in hamsters refer to the opacity or cloudiness of the lens of the eye, which can result in partially or severely decreased vision and potentially lead to permanent blindness. 

Cataracts in hamsters are characterized by a milky appearance in the eyes. This condition is more commonly seen in older hamsters and does not typically cause them pain.

The diagnosis of cataracts in hamsters is primarily based on clinical signs and observation of the cloudy appearance of the eyes. A veterinarian with experience in treating small mammals or exotic pets can provide a thorough examination to confirm the diagnosis.

While it may not be possible to prevent cataracts from occurring, providing a balanced diet, appropriate living conditions, and regular veterinary care can contribute to your hamster’s overall health and potentially delay the onset of age-related eye conditions.

Bulging eye/exophthalmos in Hamsters

Bulging eyes in hamsters, also known as exophthalmos, refers to the protrusion or bulging of one or both eyes. 

Bulging eyes in hamsters are characterized by the abnormal protrusion of the eyes, which may appear larger than usual. 

Other symptoms that may be observed include swelling, redness, and inflammation of the eyes].

Diagnostic procedures may include checking for signs of trauma, evaluating for infections, or assessing for other underlying diseases or conditions.

There can be various causes for bulging eyes in hamsters, including trauma, underlying disease, infection, or other factors. 

Treatment for bulging eyes in hamsters will depend on the underlying cause.

In cases where the condition is caused by an infection or underlying disease, appropriate medications such as antibiotics or anti-inflammatory drugs may be prescribed by the veterinarian.

Bulging eyes in hamsters should be considered an emergency and should receive immediate veterinary attention. 

Prompt diagnosis and treatment can help alleviate discomfort, prevent further complications, and improve the overall well-being of your hamster.

Glaucoma in Hamsters 

Glaucoma is a condition characterized by increased pressure within the eye, which can lead to damage to the optic nerve and potential vision loss. 

Glaucoma in hamsters is considered a severe condition, and unfortunately, there is no specific treatment available for it. 

In some cases, the eye may appear to bulge or be swollen, and in severe cases, it may even rupture.

The veterinarian will perform a thorough examination, which may include tonometry, a procedure to measure intraocular pressure. 

To manage the condition and stabilize intraocular pressure (IOP)  medication that increases aqueous outflow or decreases its production could be used. 

The disease is usually progressive, and hamsters with glaucoma may eventually experience permanent blindness and, in severe cases, loss of the affected eye.

Owners should be observant of any changes in their hamster’s behavior or signs of discomfort. In cases where blindness occurs, most hamsters can still live normal, happy lives as they rely less on vision and more on their other senses. It is important to make accommodations in the hamster’s environment to ensure their safety and well-being.
