The clear filling of the blood vessels on the white sclera of the eyeball in cats is referred to as scleritis or episcleritis. This involves an inflammatory condition or irritation that causes redness and swelling of the blood vessels in the sclera.

Can Occur with the Following Diseases:

Basics and possible causes

The sclera is the outer, protective layer of the eye, which plays an important role in maintaining the shape of the eye and protecting it from injury. When the blood vessels in this layer are irritated or inflamed, they become more prominent, making the eye appear red.

There are various causes that can lead to such an inflammatory condition. These include infections, allergies, injuries, and systemic diseases. Infections can be bacterial, viral, or fungal and often lead to a local reaction that affects the blood vessels.

Allergies are a common cause for the redness of the eyes in cats. These can be triggered by environmental factors such as pollen, dust, or mold. Chemical irritants such as cleaning agents or perfumes can also cause an allergic reaction in sensitive cats.

Injuries, whether from physical trauma or a foreign body in the eye, can also lead to irritation of the sclera. In addition, systemic diseases such as high blood pressure or autoimmune diseases can play a role. Stress and environmental factors also contribute to the deterioration by weakening the immune system and thus increasing susceptibility to inflammatory conditions.

Typical accompanying symptoms

  • Redness of the eyes: Clearly visible blood vessels and a general redness of the eyes are often the first signs of scleritis.

  • Tear flow: An increased production of tear fluid can occur as a reaction to the irritation.

  • Swelling: The eyes may appear swollen, indicating an inflammatory condition.

  • Pain or discomfort: The cat may show signs of pain, such as frequent blinking or rubbing the eyes with its paw.

  • Behavioral changes: Cats may withdraw or be less active if they experience discomfort or pain in the eye area.

  • Light sensitivity: The cat may avoid light or squint when exposed to bright light.

  • Impaired vision: In severe cases, the cat’s vision may be impaired, which could manifest as uncertainty / disorientation in movement.

When to visit the vet?

A visit to the vet is essential if the redness of the eyes lasts longer than 24 hours or is accompanied by other symptoms such as pain or behavioral changes. The cause should also be clarified in recurring cases.

If the cat shows signs of severe pain, such as persistent rubbing of the eyes or constant blinking, an immediate visit to the vet is necessary. This also applies if the cat shows signs of visual impairment.

It is particularly important to see a vet if other health problems, such as respiratory distress or loss of appetite, occur at the same time as eye irritation. These could indicate a systemic disease.

Symptom recognition for animal owners and veterinary diagnostic procedures

The pet owner can recognize the symptom by regularly observing the cat’s eyes. Changes in the color of the sclera or unusual behaviors should be taken seriously.

The veterinarian will perform a thorough examination of the cat to determine the cause of the scleritis. This includes a detailed anamnesis, in which questions are asked about the cat’s environment, possible allergens and other health problems.

Diagnostic tests may include an examination of the eyes with special instruments to rule out injuries or a foreign body in the eye. Blood tests may also be performed to identify systemic diseases that may be contributing to the eye condition.

In some cases, the veterinarian may take samples of tear fluid or tissue to test for infections. These samples are analyzed in the laboratory to identify specific pathogens and determine the appropriate treatment.

What can pet owners do and professional therapy options

As a first step to relief, the pet owner should ensure that the cat remains in a clean and dust-free environment to avoid additional irritation. It is advisable to avoid the use of potentially irritating chemicals near the cat.

Applying artificial tears or special eye drops that have been recommended or prescribed by the veterinarian can help to moisten the eye surface and regulate tear flow. However, this should only be done after consulting a veterinarian.

It is important to prevent the cat from rubbing its eyes, as this can worsen the irritation. A temporary Elizabethan collar may be necessary in severe cases to prevent further self-injury.

Regular observation of the condition of the eyes is crucial. The pet owner should pay attention to any changes and document the course of the symptoms to help the veterinarian with the treatment.

In general, the pet owner should follow all veterinary instructions carefully and contact the veterinarian immediately if there are any uncertainties in order to ensure the best possible care for the cat.

Outlook on current research

The examination of the filling of blood vessels on the sclera of cats is an important area of research, as it can often be an indicator of systemic or ocular diseases. Current studies focus on understanding the exact mechanisms that lead to increased vascular filling. This research aims to identify the pathophysiological processes that lead to increased blood flow and to clarify whether inflammatory mediators or other chemical signals play a role. A better understanding of these mechanisms could improve the diagnosis and treatment of underlying diseases.

Another focus of research is on the development of non-invasive diagnostic techniques to determine the causes of increased vascular filling on the sclera. Researchers use advanced imaging techniques such as optical coherence tomography (OCT) and confocal microscopy to obtain detailed views of the blood vessels. These technologies make it possible to observe the structure and function of the blood vessels in real time without the need for invasive procedures. Studies have shown that these techniques can help identify differences in vascular morphology that correlate with certain diseases.

An emerging area of research deals with the genetic predisposition for dilated blood vessels on the sclera. Certain cat breeds appear to be more susceptible to these symptoms, suggesting a genetic component. Genome-wide association studies (GWAS) are being conducted to identify potential genetic markers associated with increased vascular filling. In the long term, this research could lead to the development of predictive genetic tests that help veterinarians identify at-risk animals early on.

Finally, the role of environmental factors in the development of heavily filled blood vessels on the sclera is being investigated. Factors such as diet, stress and pollution could affect the health of blood vessels. Research aims to identify links between these factors and vascular health in cats. These studies are important for developing preventive measures that could reduce the risk of eye diseases.

Frequently asked questions

  1. What does it mean if the blood vessels on my cat’s sclera are very visible? Visible blood vessels on the sclera can be a sign of irritation or an inflammatory condition. It is important to identify the cause, as it can range from harmless irritation to more serious diseases.

  2. Can allergies in cats cause visible blood vessels on the sclera? Yes, allergies can lead to increased blood flow to the sclera in cats, as the body reacts to allergens and triggers an inflammatory reaction.

  3. Are visible blood vessels on the sclera in cats always a sign of a disease? Not necessarily. While they often indicate an underlying disease, they can also be caused by harmless factors such as increased activity or stress.

  4. How can I tell if the visible blood vessels on my cat’s sclera are problematic? A veterinary examination is the best way to determine the cause. The veterinarian will examine the eyes thoroughly and may order further tests.

  5. Can environmental factors affect the filling of blood vessels on the sclera? Yes, factors such as smoke, dust and other environmental pollution can irritate the cat’s eyes and lead to increased blood flow to the sclera.

  6. Does the breed of a cat play a role in the visibility of blood vessels on the sclera? Certain breeds may be more prone to eye problems, but visible blood vessels can occur in any cat, regardless of breed.

  7. Is it normal for the blood vessels on my cat’s sclera to be more visible after physical activity? Yes, after physical activity, blood flow may be increased, which can make the blood vessels on the sclera temporarily more visible.
