“Bleeding behind the eye” usually means blood has leaked from tiny retinal blood vessels into or in front of the light‑sensing tissue at the back of the eye. Doctors call this a retinal or vitreous haemorrhage. Because blood blocks or scatters light, you may notice a sudden shower of floaters, a haze, a dark patch or a “curtain” over part of your vision. It’s often painless, can range from mild to sight‑threatening, and is different to the harmless bright‑red patch you might see on the white of the eye.
This guide explains what clinicians mean by “bleeding behind the eye”, the differences between retinal and vitreous haemorrhage, and other look‑alike problems. You’ll learn common symptoms, how serious it can be, when to seek urgent care, causes and risk factors, how it’s diagnosed, and the treatments available—from laser and injections to vitrectomy—plus recovery, prevention and costs in Australia.
What doctors mean by ‘bleeding behind the eye’
Doctors generally mean an internal eye bleed in the back part of the eye (posterior segment). That’s either a retinal haemorrhage (blood within the retina) or a vitreous haemorrhage (blood leaking into the gel that fills the eye). Because the blood sits behind the pupil, you won’t see a red patch on the surface. Instead, you may notice sudden floaters, haze, shadows or a drop in vision. It’s commonly linked with trauma, diabetes‑related changes, vein blockage or high blood pressure, and needs prompt assessment.
Retinal vs vitreous haemorrhage: key differences
Both are forms of “bleeding behind the eye” (also searched as “hemorrhage behind eye”), but they happen in different places and feel different. A retinal haemorrhage is bleeding within the layers of the retina itself, while a vitreous haemorrhage is blood leaking into the clear gel (vitreous) that fills the eye and more often causes a sudden, noticeable drop in vision.
- Where it is: Retinal = inside the retina; Vitreous = into the vitreous gel.
- Typical symptoms: Retinal = may be silent or cause blur/dark spots; Vitreous = sudden painless floaters, haze, cobwebs or a shadow/“curtain”.
- Common causes: Retinal = hypertension, diabetes, vein occlusion, trauma; Vitreous = posterior vitreous detachment/retinal tear, diabetic retinopathy, trauma.
- How it’s found: Retinal = seen on a dilated exam; Vitreous = can obscure the view, often needs ultrasound.
- Treatment urgency: Retinal = treat the cause (observe/laser/injections as needed); Vitreous = dense bleeds may need vitrectomy, especially if a retinal tear is suspected.
Not the same as a red eye: subconjunctival haemorrhage
A bright‑red patch on the white of your eye is usually a subconjunctival haemorrhage, not “bleeding behind the eye”. It’s a tiny surface vessel that bursts under the clear conjunctiva. It looks dramatic but is typically harmless, painless and doesn’t affect vision or cause floaters, and it clears on its own within days to a couple of weeks. Seek care sooner if the red eye comes with pain, light sensitivity, discharge or any drop in vision.
A different emergency: retrobulbar haemorrhage after trauma
Retrobulbar haemorrhage is bleeding in the eye socket (orbit) behind the eyeball, most often after significant blunt eye/facial trauma or surgery. Unlike retinal or vitreous haemorrhage (bleeding inside the eye), this bleed sits outside the globe and can quickly raise pressure around the optic nerve. That pressure can shut down blood flow to the retina and optic nerve, risking permanent vision loss within hours, so it’s treated as an emergency.
- After an injury, seek urgent care now if you notice severe eye pain or pressure, a sudden drop in vision, a bulging eye, tight swollen lids, or double vision. In Australia, call 000 or go straight to the nearest emergency department.
Common symptoms to watch for
Most haemorrhages behind the eye are painless and start suddenly, often in one eye. Because blood scatters or blocks light inside the eye, the first clues are visual changes rather than a red-looking eye. If any of the following appear — especially after trauma or in people with diabetes or high blood pressure — get prompt assessment.
- New floaters or “cobwebs”: Small spots, threads or showers of dots.
- Hazy or cloudy vision: A smoke‑like veil across your sight.
- Sudden blur or vision drop: Painless reduction in clarity.
- Dark patches or blind spots: Areas of missing vision.
- A shadow or “curtain” effect: Worsening field loss is urgent.
- Flashes of light: Particularly when accompanied by new floaters.
Is an eye haemorrhage serious?
It can be — and you shouldn’t try to self‑diagnose. Some small retinal haemorrhages are harmless and need only monitoring. But if bleeding affects central vision, hides a retinal tear, or is linked to conditions like diabetic retinopathy or a vein occlusion, it can threaten sight. Vitreous haemorrhage typically causes sudden, painless vision loss and needs prompt assessment to rule out a tear or detachment. The rule of thumb: treat any “hemorrhage behind eye” as urgent until an eye specialist examines you — early treatment protects vision.
When to seek urgent care
If you suspect a haemorrhage behind the eye, time matters. Many cases are painless, so don’t wait for discomfort as a cue. Treat sudden changes as an emergency until an eye specialist has examined you. Fast assessment can prevent permanent vision loss, especially if a retinal tear or detachment is present.
- Go to the emergency department (call 000 in Australia) now for: sudden loss of vision or a spreading “curtain” shadow; a shower of new floaters with flashes (especially after trauma); severe eye pain or pressure; or vision changes following eye/facial injury or surgery.
- Arrange same‑day urgent assessment for new floaters, haze or dark spots, even if painless — particularly if you have diabetes or high blood pressure.
What causes bleeding behind the eye
Bleeding behind the eye happens when fragile or damaged retinal vessels leak into the retina or the vitreous gel. Triggers include traction from the vitreous, vessel blockages or disease, sudden pressure shifts and direct injury. Identifying the cause of a “hemorrhage behind eye” (haemorrhage) guides both treatment and prognosis.
- Trauma (eye/head).
- Posterior vitreous detachment (PVD) with a retinal tear.
- Diabetic retinopathy.
- Retinal vein occlusion; high blood pressure (vascular disease).
- Wet age‑related macular degeneration.
- Blood disorders (anaemia, sickle cell) or use of blood thinners.
- Pressure shifts (Valsalva, rapid altitude change or diving ascent).
- Less common systemic causes: infections/inflammation (endocarditis, vasculitis) and leukaemia.
Who is most at risk
You’re more likely to have a haemorrhage behind the eye if you have conditions that damage retinal blood vessels, age‑related changes in the vitreous or retina, or recent trauma/surgery. Risk rises with diabetes, high blood pressure or cholesterol, and blocked retinal veins. After 40, posterior vitreous detachment and macular degeneration become common triggers. Blood‑thinning medicines and some blood disorders also raise the likelihood.
- Diabetes and vascular disease: Diabetes (diabetic retinopathy), high blood pressure and high cholesterol.
- Ageing changes (40+): Posterior vitreous detachment and macular degeneration.
- Other factors: Retinal vein occlusion; blood thinners or blood disorders; eye/head trauma or surgery; sudden pressure shifts (Valsalva, rapid altitude change, diving).
How your condition is diagnosed
Assessment starts with your story — when symptoms began, any recent trauma, and medicines (especially blood thinners) — followed by a same‑day eye examination. Your specialist will check vision and examine the back of the eye after dilating the pupil. The priority is to find the source of bleeding behind the eye and rule out a retinal tear or detachment.
- Slit‑lamp and dilated fundus exam: To see retinal or vitreous haemorrhage directly.
- Optical coherence tomography (OCT): High‑resolution scans of the macula and retina.
- Ultrasound (B‑scan): Crucial if blood obscures the view, to look for tears/detachment.
- Fluorescein angiography: Maps leaking or blocked retinal vessels when needed.
- Blood tests +/- imaging: Checks for diabetes, cholesterol, anaemia; CT/MRI if pressure‑related causes are suspected.
Treatment options for retinal haemorrhage
Treatment for a haemorrhage behind the eye that sits in the retina targets the cause and how much it threatens vision. Many small bleeds need monitoring only, but sight‑affecting or recurrent haemorrhages — especially with diabetes, vein occlusion or hypertension — need active care. Your ophthalmologist will tailor a plan after examination and imaging.
- Optimise systemic health: Manage diabetes, blood pressure and cholesterol; review blood thinners with your GP (don’t stop them without advice).
- Laser or cryotherapy: To repair or seal leaking/abnormal vessels and stabilise retina.
- Injections (anti‑VEGF or corticosteroid): To reduce leakage, swelling and abnormal vessel growth.
- Urgent tear/detachment care: Laser/cryo retinopexy or surgery to reattach the retina if present.
- Observation with close follow‑up: Small, stable haemorrhages often resolve without intervention.
Treatment options for vitreous haemorrhage
Management focuses on how much the bleed affects vision, what caused it, and whether there’s a retinal tear or detachment. After urgent examination (often with ultrasound), small, stable vitreous haemorrhages can be observed while the eye clears blood over days to weeks. If vision is significantly impaired, the bleed doesn’t clear, or a tear/detachment is present, active treatment is needed.
- Conservative care: Short period of observation and activity modification while monitoring closely.
- Focal treatments: Precisely applied laser or cold therapy to seal a retinal tear or abnormal vessels.
- Medications (anti‑VEGF): Limit abnormal vessel growth and leakage, particularly in diabetes or vein blockages.
- Surgery (vitrectomy): Removes the blood‑filled vitreous and replaces it with saline, silicone oil or a gas bubble; used for dense/non‑clearing bleeds or when a tear/detachment is suspected.
Laser therapy, injections and vitrectomy explained
Most treatments aim to seal or remove the source of a haemorrhage behind the eye and to curb fragile new vessels that bleed again. Your ophthalmologist may use one or a combination of these, depending on the cause (for example diabetes, vein occlusion or a retinal tear), the amount of blood and how much your vision is affected.
- Laser therapy: Precisely seals retinal tears and treats leaking or abnormal vessels, helping stabilise the retina. It’s used urgently for tears and commonly in diabetic eye disease or vein blockages.
- Injections (anti‑VEGF or corticosteroid): Medicines placed inside the eye to reduce leakage, swelling and abnormal vessel growth. Often used for diabetic retinopathy, retinal vein occlusion and wet macular degeneration.
- Vitrectomy surgery: Removes blood‑filled vitreous and replaces it with saline, silicone oil or a gas bubble. Recommended for dense or non‑clearing vitreous haemorrhage, or when a retinal tear/detachment is suspected. If a gas bubble is used, you’ll receive positioning instructions and must avoid flying until it dissipates.
Recovery, vision prognosis and recurrence
Recovery depends on the cause, how much bleeding there is, and whether the macula or a retinal tear/detachment is involved. Small retinal haemorrhages often clear with observation and vision may return fully. Vitreous haemorrhage can settle over days to weeks as blood reabsorbs, but dense bleeds may take longer or need vitrectomy. After laser, injections or vitrectomy, most people improve over the following weeks; final vision hinges on the underlying retinal health and how quickly treatment began.
- Better outlook: Small, peripheral bleeds; prompt treatment; healthy retina.
- Guarded prognosis: Macula‑involving bleeds; diabetic retinopathy or vein occlusion.
- Lower recurrence: Good diabetes/BP control, targeted laser/anti‑VEGF, careful review of blood thinners.
Living safely while you recover
While a haemorrhage behind the eye (hemorrhage behind eye) is healing — or after laser, injections or vitrectomy — a few simple steps help protect vision and prevent re‑bleeding. Your ophthalmologist’s instructions come first; the points below are general guidance.
- Follow-up and drops: Use all prescribed drops and attend every review. Don’t change blood thinners without medical advice.
- Go gently: For 1–2 weeks avoid heavy lifting, straining and high‑intensity exercise; sneeze or cough with your mouth open.
- If you have a gas bubble: Keep the positioning advised, don’t sleep on your back and do not fly until the bubble has gone.
- Protect the eye: Wear a night shield for the first week, don’t rub the eye and avoid swimming or eye make‑up until cleared.
- Drive safely: Only drive once your vision meets legal standards.
- Mind your health: Keep blood sugar and blood pressure well controlled; avoid NSAIDs unless your doctor approves.
- Watch for warnings: New curtain‑like shadow, sudden vision drop, increasing floaters/flashes, severe pain or redness need urgent assessment.
Preventing future problems and protecting your sight
Most “bleeding behind the eye” events are preventable or less likely to recur when the underlying vessel disease is controlled and you act early on new symptoms. Focus on systemic health, sensible eye protection and regular reviews. If you’ve had a haemorrhage behind the eye before, staying on top of these steps lowers the chance of another.
- Manage diabetes, blood pressure and cholesterol: Good control reduces fragile vessel leakage and new bleeding.
- Don’t smoke: Smoking damages retinal blood vessels and slows healing.
- Keep regular dilated eye exams: Follow your specialist’s schedule; people with diabetes need more frequent checks.
- Use protective eyewear: Wear safety glasses for DIY, sport or risky work to prevent trauma‑related haemorrhage.
- Review blood thinners safely: Never stop on your own; ask your GP/specialist if adjustments are appropriate.
- Avoid sudden pressure spikes: Go easy on heavy straining; treat cough/constipation; be cautious with rapid altitude changes or diving ascents.
- Act fast on warning signs: New flashes, a shower of floaters, haze or a “curtain” over vision need same‑day assessment.
- Live heart‑healthy: Balanced diet, regular exercise and a healthy weight support retinal vessel health.
Costs, rebates and access to care in Australia
In Australia, care for a haemorrhage behind the eye is available publicly and privately. Medicare subsidises specialist visits and imaging; public hospitals provide emergency care and surgery when required. Private patients with hospital cover can choose their surgeon. Many clinics, including Bright Sight, offer transparent fees and no‑gap cataract options.
- Medicare rebates: Consults/tests rebated; gap depends on clinic.
- Private insurance: Hospital costs covered; excess and any known‑gap apply.
- Injections/laser: Often Medicare/PBS‑subsidised; out‑of‑pocket varies by drug.
- Fast access: Same‑day optometrist/GP referral, or ED for sudden vision loss.
Frequently asked questions
Here are quick answers to common questions about a haemorrhage behind the eye. Remember: sudden vision changes are urgent until an eye specialist has examined you.
- Is it painful? Most retinal/vitreous haemorrhages are painless; retrobulbar haemorrhage after trauma is painful and an emergency.
- Will it go away on its own? Small retinal bleeds often settle; mild vitreous haemorrhages can clear over days to weeks. Always get assessed to rule out a tear/detachment.
- How long does recovery take? Blood may clear in days to weeks; surgery recovery is usually a few weeks.
- Should I stop blood thinners? No. Don’t stop without medical advice; your doctors may adjust them.
- Can I fly? If a gas bubble was used in surgery, do not fly until it has fully gone.
- Can it happen again? Yes; controlling diabetes and blood pressure and targeted treatment lowers the risk.
Next steps
If you’ve noticed sudden floaters, haze, a “curtain”, or a drop in vision — don’t wait. As we covered, “bleeding behind the eye” can be minor or vision‑threatening. Early diagnosis finds tears and treats underlying causes (diabetes, vein blockages, macular degeneration) before permanent damage.
