Hyphema in Cats: Vet Guide 🐱👁️ 2025
By Dr Duncan Houston BVSc, veterinarian & founder of Ask A Vet.
Hyphema means blood pooling in the front chamber of the eye (the anterior chamber). It’s often alarming to pet owners, but early veterinary care can preserve vision 💡.
🧭 What Is Hyphema?
Hyphema occurs when blood leaks from damaged retinal or uveal vessels into the anterior chamber—between the cornea and iris.
🚨 Signs & Symptoms
Look out for these key signs:
- 🔴 **Red or Bloody Eye** – ranging from light pink to deep red clots.
- 🛑 Visible clot or blood settling at the bottom of the chamber).
- 😹 Squinting, pawing at eye, corneal haze/swelling (edema), and inflamed conjunctiva.
- 👁️ Small pupil (miosis), larger eyeball (buphthalmos), hypopyon (white inflammatory debris).
- ❌ Impaired vision or blindness.
- ⚠️ Other bleeding signs – bruises, blood in vomit/stool (systemic issues).
💥 Causes of Hyphema
Hyphema is a **sign**, not a standalone disease—identifying the cause is vital :
- 🔫 **Trauma** – blunt force or penetrating injuries (e.g., fights, accidents).
- 🦠 **Ocular inflammation (uveitis)** – from infections or immune diseases.
- 💓 **Hypertension** – often tied to kidney disease or thyroid issues.
- 🎗 **Tumors** – in or around eye blood vessels.
- 🧪 **Coagulopathies or toxins** – e.g., rodent poison exposure.
- 🫀 **Glaucoma, lens displacement, or retinal detachment**.
🔍 Diagnosing Hyphema
Diagnosis involves confirming blood in the eye and uncovering the root cause:
- 👁️ **Ocular exam** – assess vision, reflexes, pupil size, cornea clarity.
- 🧪 **Tonometry** – check intraocular pressure for glaucoma risk.
- 🧴 **Fluorescein stain** – detect corneal ulcers.
- 💧 **Schirmer tear test** – evaluate tear production.
- 🩸 **Blood and organ tests** – CBC, kidney/liver values, clotting profiles, thyroid, blood pressure.
- 🔬 **Infection screens** – for tick-borne disease, FeLV/FIV, FIP etc..
- 🩻 **Ocular ultrasound/X-ray** – check retina, lens, tumors.
🩺 Treatment Plan
Treatment aims to:
- 🩹 Manage the bleeding
- 🛑 Control pain & inflammation
- ❤️ Address the underlying cause.
👁️ Eye-Specific Therapy
- 💊 **Topical anti-inflammatories** – NSAIDs (flurbiprofen, diclofenac) or steroid drops (prednisolone acetate).
- 🔒 **Atropine drops** – dilate pupil to ease ciliary spasm discomfort.
- 🧪 **TPA injections** – in select cases to dissolve clots.
- 💉 **Systemic NSAIDs or steroids** – for inflammation alongside ocular meds.
🩸 Treating the Root Cause
- 🔪 **Surgery or chemo** – for ocular tumors.
- 🩺 **Manage hypertension** – via BP meds.
- 🦠 **Treat infections or immune diseases**.
- 🚫 **Correct clotting issues** – blood transfusions if necessary.
- 🏥 **Glaucoma** meds or **lens surgery**, if caused by displacement.
⚠️ Severe Cases
In refractory or blind severe hyphema, **enucleation**—removal of the eye—may be advised.
📅 Prognosis & Recovery
Prognosis depends on the severity and cause:
- ✅ Mild cases often resolve in 1–2 weeks with proper care.
- ⚠️ Risk of complications—glaucoma, corneal staining, rebleeds, optic damage—if underlying issues persist.
- 🚨 Recurrent or chronic hyphema generally carries a poorer outlook.
🏠 Home Care & Monitoring
- 💧 Administer medications on time, per vet instructions.
- ⏰ Keep follow-up visits every 3–7 days initially, then adjust based on healing.
- 🚫 Prevent eye trauma—keep your cat calm and away from hazards.
