🐾 Vet’s Guide to Retinal Hemorrhage in Cats: Causes, Symptoms & Treatment in 2025 🐾

By Dr Duncan Houston BVSc

Retinal hemorrhage in cats is a serious condition involving bleeding into the retina, the light-sensitive tissue at the back of the eye. This can lead to vision impairment or loss and may indicate underlying systemic health issues. Understanding the causes, recognizing the symptoms, and seeking prompt veterinary care are crucial for your feline friend's well-being. This guide provides comprehensive information on retinal hemorrhage in cats, tailored for Australian cat owners in 2025.

🔬 Understanding Retinal Hemorrhage

The retina is responsible for converting light into neural signals for vision. Hemorrhage occurs when blood vessels within the retina rupture, leading to bleeding that can disrupt normal vision and, in severe cases, cause retinal detachment.

🦠 Causes of Retinal Hemorrhage

Several factors can lead to retinal hemorrhage in cats:

• 🐾 Systemic Hypertension: High blood pressure, often due to kidney disease or hyperthyroidism, can damage retinal vessels.
• 🐾 Trauma: Injuries to the head or eyes can cause bleeding within the retina.
• 🐾 Blood Clotting Disorders: Conditions like anemia or coagulopathies can increase bleeding risk.
• 🐾 Infections: Bacterial, viral, or fungal infections may lead to inflammation and hemorrhage.
• 🐾 Neoplasia: Tumors affecting the eye or systemic cancers can cause retinal bleeding.
• 🐾 Diabetes Mellitus: Chronic high blood sugar levels can damage retinal blood vessels.
• 🐾 Genetic Predisposition: Certain breeds may be more susceptible due to inherited conditions.

🐱 Recognizing Symptoms

Symptoms of retinal hemorrhage can vary but may include:

• 🐾 Sudden vision loss or blindness
• 🐾 Dilated or non-responsive pupils
• 🐾 Bumping into objects or disorientation
• 🐾 Visible blood in the eye or redness
• 🐾 Squinting or signs of eye discomfort
• 🐾 Behavioral changes due to impaired vision

It's important to note that some cats may not show obvious signs, especially if only one eye is affected.

🧪 Diagnosis

Diagnosing retinal hemorrhage involves:

• 🐾 Comprehensive Eye Examination: Using ophthalmoscopes to inspect the retina.
• 🐾 Blood Pressure Measurement: To detect systemic hypertension.
• 🐾 Blood Tests: Including complete blood count and coagulation profiles.
• 🐾 Imaging: Ultrasound or advanced imaging if the retina cannot be visualized directly.
• 🐾 Assessment for Underlying Diseases: Evaluating for conditions like kidney disease or diabetes.

💊 Treatment Options

Treatment focuses on addressing the underlying cause and managing the hemorrhage:

• 🐾 Medications: Antihypertensives for high blood pressure, insulin for diabetes, or antibiotics for infections.
• 🐾 Supportive Care: Ensuring a safe environment to prevent injury due to vision impairment.
• 🐾 Surgical Intervention: In cases of retinal detachment, surgery may be necessary to reattach the retina.
• 🐾 Monitoring: Regular follow-ups to assess healing and adjust treatments as needed.

🛡️ Prevention Strategies

Preventing retinal hemorrhage involves proactive health management:

• 🐾 Regular veterinary check-ups to monitor blood pressure and overall health.
• 🐾 Managing chronic conditions like kidney disease or diabetes effectively.
• 🐾 Protecting your cat from trauma by keeping them indoors or supervising outdoor time.
• 🐾 Being vigilant for signs of eye issues and seeking prompt veterinary attention.

📍 Considerations for Australian Cat Owners

In Australia, environmental factors and common feline health issues necessitate particular attention:

• 🐾 Climate: Hot temperatures can exacerbate certain health conditions; ensure your cat stays hydrated and cool.
• 🐾 Parasites: Regular parasite control can prevent infections that may lead to systemic illness.
• 🐾 Breed-Specific Risks: Some breeds prevalent in Australia may have genetic predispositions; consult your vet about your cat's specific risks.
