What is Hyphema in Dogs? Symptoms, Causes, Diagnosis, and Treatment

Hyphema in dogs

Canine hyphema is a condition that can lead to partial or complete vision impairment if left untreated. Understanding its symptoms, causes, and treatment options can help pet owners take the necessary steps to protect their dog’s eye health.

What is Hyphema in Dogs?

Hyphema in dogs is a serious condition where blood collects in the anterior chamber of the eye, the space between the cornea and the iris. The severity can range from a light reddish tinge to complete blood filling, which may cause partial or total vision loss. Hyphema itself is not a disease but rather a symptom of an underlying issue, making early detection and treatment critical.

Symptoms of Hyphema in Dogs

Dogs suffering from hyphema may display several symptoms, including:

  • Visible Blood in the Eye – Blood may appear as a faint red discoloration or a heavy pooling that obscures vision.

  • Cloudy or Hazy Appearance – The presence of blood can make the eye look foggy.

  • Squinting or Frequent Blinking – Indicating discomfort or pain.

  • Swelling Around the Eye – Inflammation may develop alongside the bleeding.

  • Increased Tearing or Discharge – The eye may produce excess tears as a response to irritation.

  • Pawing at the Eye – Dogs in discomfort often try to rub or paw at their affected eye.

  • Vision Impairment – You may notice that your dog bumps into furniture or has trouble navigating familiar spaces.

Recognizing these symptoms early and seeking veterinary care can prevent further complications.

Causes of Hyphema in Dogs

Hyphema can result from various medical conditions and injuries. The most common causes include:

1. Trauma and Injury

  • Direct blunt force trauma from accidents, falls, or rough play can rupture blood vessels in the eye.

  • Foreign objects such as sticks or debris can cause injury leading to bleeding.

  • Bites or scratches from other animals may also lead to ocular damage.

2. Systemic Diseases

  • Hypertension (High Blood Pressure): Increased pressure in the blood vessels can cause spontaneous bleeding.

  • Coagulopathies (Blood Clotting Disorders): Conditions such as hemophilia affect clot formation, making bleeding more likely.

  • Diabetes: Poorly controlled diabetes can contribute to vascular damage in the eyes.

  • Infectious Diseases: Canine ehrlichiosis and leptospirosis may result in hyphema due to systemic bleeding tendencies.

3. Ocular Diseases

  • Uveitis: Inflammation of the uveal tract can weaken blood vessels, leading to bleeding.

  • Glaucoma: Increased intraocular pressure can cause blood vessel rupture.

  • Retinal Detachment: Separation of the retina can lead to bleeding in the anterior chamber.

  • Intraocular Tumors: Masses inside the eye may disrupt normal vascular function, causing hyphema.

4. Congenital and Genetic Factors

Some dog breeds are genetically predisposed to conditions that may cause hyphema. Breeds with a higher risk include Cavalier King Charles Spaniels (prone to retinal disease) and Dobermans (prone to clotting disorders).

Diagnosing Hyphema in Dogs

A thorough veterinary examination is essential for diagnosing hyphema and its root cause. The diagnostic process typically includes:

1. Veterinary Ophthalmic Exam

  • The veterinarian will assess the eye using an ophthalmoscope to evaluate internal structures.

  • Fluorescein staining may be used to check for corneal injuries.

2. Tonometry

  • This test measures intraocular pressure to rule out glaucoma, which can contribute to hyphema.

3. Ocular Ultrasound

  • If the presence of blood obscures the eye’s internal structures, ultrasound imaging helps assess the retina and optic nerve.

4. Blood Tests and Coagulation Profiles

  • These tests check for clotting disorders, infections, or systemic diseases like hypertension and diabetes.

5. Blood Pressure Measurement

  • Since high blood pressure can be a cause of hyphema, measuring a dog’s blood pressure is crucial for diagnosis.

6. Imaging (X-rays, Ultrasound, or MRI)

  • If an underlying systemic disease or tumor is suspected, further imaging studies may be necessary.

Accurate diagnosis ensures that treatment is tailored to address both hyphema and the underlying cause.

Treatment Options for Hyphema in Dogs

Treatment depends on the severity and root cause of the hyphema. Managing both the symptom and its cause is essential to prevent recurrence.

1. Medical Treatment

  • Anti-inflammatory Medications: If inflammation is present, corticosteroid or non-steroidal eye drops may be prescribed.

  • Pressure-Reducing Medications: If glaucoma is detected, pressure-lowering eye drops will be needed.

  • Pain Management: Analgesics may be given to reduce discomfort.

  • Antibiotics or Antivirals: If an infection is the cause, appropriate medications will be prescribed.

2. Surgical Intervention

  • If there is significant blood accumulation or complications such as retinal detachment, surgery may be required.

  • In some cases, laser therapy can help repair damaged blood vessels.

3. Management of Underlying Conditions

  • Hypertension, clotting disorders, and infections must be managed with appropriate treatments to prevent recurrence.

4. Supportive Care

  • Keeping your dog in a calm, safe environment to avoid further injury.

  • Restricting high-energy activities that could exacerbate the condition.

Helping Dogs with Vision Impairment

If hyphema results in partial or permanent vision loss, supporting your dog’s ability to navigate their surroundings becomes crucial.

Supporting Your Dog’s Eye Health

Ensuring your dog’s eye health is a long-term commitment. Here are steps you can take to maintain healthy vision and prevent conditions like hyphema:

  • Schedule regular veterinary check-ups, including eye exams.

  • Protect your dog’s eyes from trauma by supervising play and outdoor activities.

  • Monitor for early signs of eye conditions such as redness, discharge, or changes in behavior.

  • Maintain a healthy diet to support ocular health.
