Vitreous Hemorrhage After a Blow to the Eye: What Happens Next
Bleeding Inside the Eye After an Injury at a Glance
An eye that bleeds inside after a blow needs to be seen today, not next week. Go to an emergency room, or ask your eye doctor for a same day visit, if you notice any of these after an eye injury:
- A sudden drop in vision, or a dark shadow or curtain in your side vision
- A shower of new floaters, or flashing lights off to the side
- Severe eye pain, or an eye that looks cut, misshapen, or leaking
- Blood covering the colored part of the eye
- A pupil that no longer matches the other one
- Double vision, pain when you move the eye, or a numb cheek
Most blunt eye injuries are not the worst kind. Speed still matters. A cut or burst eye wall is a surgical emergency, and a scan can miss one, so surgeons are told to open and check the eye when doubt remains1. A torn retina after an injury usually needs treatment, and a detached retina goes back in place more often, with better vision after, when it is repaired early2. So the next step is simple. Get the eye looked at now, and let the exam sort out which problem you have.
The back of your eye is filled with a clear gel called the vitreous. Light passes through it to reach the retina, the light-sensing layer at the back. A vitreous hemorrhage is bleeding into that gel. Blood is not clear, so it blocks the light on its way through, and vision goes hazy, smoky, or dark.
After a blow, that blood is a signal as much as a symptom. Something inside tore or bruised hard enough to break a vessel. The blood itself usually clears. The urgency is about what it may be hiding: a tear or detachment of the retina your doctor cannot see through it.
You will have a dilated eye exam. If the blood is too thick for your doctor to see the retina, the next step is usually an ultrasound scan, which reads through blood the way light cannot. A tear or detachment gets treated quickly. If nothing turns up, you are still booked to come back, because a clear first look does not close the question.
What a Vitreous Hemorrhage Actually Is
The vitreous gel fills most of the eye and sits against the retina. It has no blood vessels of its own, so any blood in it came from somewhere else, usually from retinal vessels that tore. How much vision drops depends on how much blood sits in your line of sight, and the usual complaints are painless floaters, haze, cobwebs, or a shadow3.
Bleeding into the vitreous is reported in roughly 7 of every 100,000 people each year, and it is more common between ages 40 and 59, in men, and in people taking blood thinners4. Most cases overall come from diabetic eye disease or retinal detachment rather than from an injury4.
Trauma is a different story by age. Injury is the leading cause of vitreous hemorrhage in people younger than 405. If you are young and healthy, a blow is the most likely explanation for blood inside your eye.
A blunt object cannot cut the eye, so it does something else. The impact squashes the eyeball for a fraction of a second, and it widens sideways to compensate. That stretch pulls on tissues that do not stretch well, including the retina and its vessels, and it can tear the retina or shake the lens loose in the same moment. Bleeding into the gel happens when normal vessels rupture, when abnormal new vessels bleed, or when blood tracks in from a neighboring structure, and it is rupture of normal vessels that drives traumatic bleeds5.
The Injuries That Often Travel With the Bleeding
The blood is the part you notice, and other things may have been hurt in the same moment. In a series of 33 eyes with severe bleeding after a blunt, closed globe injury, about 45 of every 100 eyes had one or more injuries at the back of the eye hidden under the blood6. Here is what your doctor looks hardest for.
| What can be injured | Why your doctor hunts for it |
|---|---|
| A tear in the retina | It can lead to a detachment, and it is treatable in clinic once seen |
| A detached retina | It needs surgery, and timing changes the result |
| Blood under the macula | The macula is the center of sight, so damage there is felt directly |
| A break in the choroid, the layer under the retina | It can leave a lasting blind spot if it runs through the center |
| Bleeding in the front of the eye, called hyphema | It can push the eye pressure up and needs its own monitoring |
Two figures set the tone here. In that same series of 33 eyes, retinal tears were found in about 18 of every 100 eyes, and retinal detachment in about 18 of every 1006. It is one small study, so treat the numbers as a rough shape, not a risk score for you.
A much larger record points the same way. Among 206,807 adults with a blunt eye injury tracked in a national registry for an average of 444 days, about 8 of every 1,000 needed retinal detachment repair and about 8 of every 1,000 needed treatment for a retinal break, and bleeding into the vitreous at the first visit was the strongest predictor of both in the first 60 days7. Read that carefully: most injured eyes never need either. Yours has the finding that raises the odds, which is why you are watched closely.
Some things shift the risk. Being nearsighted, having had cataract, glaucoma or other eye surgery, having had a tear or detachment in the other eye, or having weak areas your eye doctor has already noted all raise the risk of a retinal tear or detachment8. Taking a blood thinner is linked to a higher chance of bleeding into the vitreous in general4. A fast impact, such as a squash ball, carries more force than a slow bump.
What You Notice, and What You Might Not
Most people describe a sudden change with no pain in the eye itself, even when the area around it aches from the blow. Vision may look smoky, red-tinged, or like looking through dirty water. Some see a swarm of dark dots that drift with eye movement, and how far vision drops depends on how much blood sits in the visual axis3. None of those descriptions tells you how bad the damage is.
Vision after a vitreous hemorrhage is often worse in the morning, because blood settles back over the macula while you lie flat overnight9. It usually improves through the day as the blood sinks again, so the eye can feel like it loses ground each night.
Track the trend across days, not hours. A morning slightly clearer than last week is progress. A drop that does not lift by evening is worth a phone call.
Some changes matter more than others. A new curtain or shadow moving in from the side, a fresh burst of flashing lights, or a clear drop in vision from yesterday are the ones to report. Guidance for people with bleeding in the vitreous is to be seen again promptly if new symptoms appear, rather than waiting for the next booked appointment10.
That is not a reason to test your vision every hour. It is a reason to know those three signals, compare your eyes once a day, and act without hesitating.
How Doctors Look Behind the Blood
Expect drops to widen the pupil and a bright light while your doctor looks in. They check the pressure inside the eye, look at the front for blood, and try to see the retina. Double vision, pain on moving the eye, or a numb cheek or teeth point to a fracture of the thin bones around the eye and need to be checked11. The drops blur your near vision for hours, so arrange a lift home.
Blood stops light, but not sound. A B-scan ultrasound is recommended when blood blocks a full view of the back of the eye12. A small probe rests on the closed eyelid over gel, and the picture shows the shape of the retina behind the blood. It takes a few minutes and does not hurt.
If there is any suspicion that the wall of the eye is cut or open, or that something is inside the eye, imaging is added. Across nine studies covering 917 injured eyes, a CT scan correctly identified about 77 of every 100 eyes that really had an open wall and correctly cleared about 94 of every 100 that did not, so surgeons are advised to explore the eye when doubt remains1. In plain terms, a normal scan lowers the concern without settling it.
If an open eye wall is suspected, you may be asked not to eat or drink, and a shield may be taped over the eye. That is preparation for possible surgery, not a verdict.
Repeat examination every two or three weeks is used to rule out a retinal break or detachment hidden beneath the blood12. Guidance for people with vitreous bleeding is a second examination within 6 weeks, and sooner if new symptoms appear10. Each visit sees further in than the last as the blood clears. Missing them is the most common avoidable mistake after this injury, because they are how a tear gets found while it is still simple to treat.
Treatment: Watching, Waiting, and When Surgery Is Right
If the retina is attached and no tear is visible, most doctors observe rather than operate. Conservative management uses head elevation and observation, over roughly 3 to 7 days while the cause is unclear, and roughly 2 to 4 weeks once the cause is known and the retina is confirmed attached13. Blood in the gel does not respond to drops or tablets.
Blood clears from the gel slowly, at a rate of roughly 1 part in 100 per day9. Knowing that in advance stops a slow recovery from feeling like failure.
Limiting activity and raising the head of the bed while sleeping may let blood settle to the bottom of the eye, out of your line of sight14. Two extra pillows or a wedge is enough. Be honest about the evidence: this is sensible practice rather than a tested treatment.
How honest? In 30 trials covering 2,969 people with bleeding in the front of the eye after injury, no treatment studied, including bed rest, patching and head elevation, showed an effect on final vision, though medicines that slow clot breakdown did reduce repeat bleeding15. Those trials looked at the front of the eye, not the gel, so they do not settle your case. They do explain why your doctor is relaxed about pillows and firm about appointments.
Two questions get tangled here. In the hours after a blow to the eye, avoid aspirin, ibuprofen and other blood-thinning medicines for the pain, do not rub the eye, and use a small cold compress gently without pressing on it16. Ask your doctor or pharmacist what to use for the pain instead.
The second question is about a blood thinner you were already prescribed. Aspirin and other anticoagulant medicines are generally not stopped after a vitreous hemorrhage develops14. Never stop one on your own, because the reason it was started has not gone away. Ask the doctor who prescribed it and your eye doctor to make that call together.
Surgery to remove the gel and the blood is called a vitrectomy. It is indicated when the bleeding comes with a retinal detachment, an open globe injury, infection inside the eye, or raised pressure from the blood, when the hemorrhage is long-standing, when both eyes are affected or the injured eye is the only seeing one, and for children at risk of a lazy eye17. A retinal tear found at any point usually needs treatment, and a peripheral horseshoe tear is treated with laser or freezing2.
Where a tear and detachment have been ruled out, timing is a judgment your surgeon makes with you, weighing how long you have waited and how much vision you need day to day.
Risks, Complications, and the Realistic Outlook
Outcomes depend on what else was damaged, and the honest picture for severe bleeds is mixed. In the series of 33 eyes with severe bleeding after a blunt injury, final vision reached 20/40 or better in about 21 of every 100 eyes and stayed worse than 20/200 in about 54 of every 100, and the authors called the visual outlook guarded6. Those eyes were picked for severe hemorrhage, so they sit at the difficult end.
A modest bleed with an intact retina generally does better. No page can say which group your eye is in. Your exam and your ultrasound answer that.
When blood stays in the gel beyond about a year, it can lead to ghost cell glaucoma, in which old red blood cells clog the eye's drainage and raise the pressure, and to hemosiderosis bulbi, in which iron released from the blood damages the tissues of the eye18. Both take time to build, which is why your doctor watches the clock rather than waiting indefinitely. If your bleed is months old and not shifting, expect that conversation.
An eye that comes through a blunt injury well can still develop trouble later. In the registry of 206,807 blunt eye injuries, bleeding into the vitreous stayed a significant predictor of needing retinal break treatment or detachment repair even beyond 60 days after the injury7. In the same group, about 28 of every 1,000 went on to cataract surgery and about 3 of every 1,000 to glaucoma surgery7.
That does not mean living on alert forever. It means a yearly dilated eye exam, mentioning the injury each time, and treating any new floaters, flashes or shadow as urgent rather than familiar.
When to Call, and Who Should Look After You
Call your eye doctor the same day, or use an emergency eye service, if any of these appear while you wait for the blood to clear:
- A new shadow or curtain creeping across your side vision
- A fresh burst of flashing lights, or a sudden increase in floaters
- Vision that clearly drops rather than slowly improving
- Deep aching pain in the eye, or a hard, red eye
- Nausea or vomiting alongside eye pain, which can signal high pressure
Ongoing eye pain, trouble seeing, an eye that does not move normally, an abnormal pupil, or blood in the clear part of the eye all mean the eye should be examined rather than watched at home16. Calling early costs you an appointment. Calling late can cost more, and no one will think you overreacted.
Your schedule depends on what was found. The pattern below is the common shape, not your plan.
| When | What usually happens |
|---|---|
| Day of injury | Dilated exam, pressure check, ultrasound if the retina cannot be seen |
| First one to two weeks | Repeat exam and often a repeat ultrasound |
| Every two to three weeks after | Checking for a tear or detachment as the blood thins |
| Within six weeks | A further full examination, sooner if symptoms change |
| Long term | An annual dilated exam, mentioning the old injury each time |
Bleeding in the vitreous after trauma is usually handled by a retina specialist, an ophthalmologist with extra training in the back of the eye. An optometrist or a general ophthalmologist may see you first and arrange the referral, which is a safe route as long as it happens quickly. If an emergency department told you to follow up, treat that as part of the treatment, and book before you leave.
Return-to-activity timing is set by your ophthalmologist, and it depends on whether a tear was treated, whether you had surgery, and whether gas was placed in the eye. Contact sport and heavy lifting usually come back last, and driving deserves its own question, since vision in one eye affects depth judgment and legal standards vary by state. Nearly 30,000 sports-related eye injuries are treated in United States emergency rooms each year, and most serious eye injuries could be avoided with appropriate protective eyewear using shatterproof polycarbonate lenses19. Everyday glasses are not eye protection.
Questions People Ask After an Eye Injury
Usually, yes, if the retina is intact. Blood leaves the gel at a rate of roughly 1 part in 100 per day9, so a dense bleed takes weeks to months. Nothing you can buy speeds it up. The reason your doctor still wants to see you repeatedly is not the blood, it is what the blood might be hiding.
There is no fixed answer, because it depends on how much blood there is and what else was injured. Many people notice steady improvement over several weeks as the blood settles and thins. Judge progress week by week, since vision often looks worst in the morning. If it drops rather than improves, that is a same-day reason to call your eye doctor.
Raising the head of the bed is commonly advised. Limiting activity and elevating the head while sleeping may allow blood to settle downward, away from your line of sight14. Two pillows or a foam wedge does the job, and you do not need to sit bolt upright. Treat it as positioning rather than a treatment that changes the result.
Do not change it on your own. Aspirin and other anticoagulants are generally not stopped after a vitreous hemorrhage develops14, because the clot risk they were started for is still there. Tell your eye doctor what you take, and let them speak with whoever prescribes it. Separately, avoid aspirin or ibuprofen as a painkiller right after the blow.
Because a tear in the retina can be silent and invisible under fresh blood. Guidance is a second examination within 6 weeks for people with vitreous bleeding, and sooner if new symptoms appear10. Each visit lets your doctor see deeper as the blood clears. A tear found at a check is a small clinic procedure. Found after the retina detaches, it means surgery.
Ask your own ophthalmologist, because the answer depends on what they found. In general, activity is limited while blood is still settling, and heavy lifting, contact sport and anything that risks another blow return last. If a tear was treated, or you had surgery, your surgeon sets the timeline. Walking is usually fine early on.
More Questions About Surgery, Children, and the Long Run
Many people do not. Vitrectomy is used when the bleeding comes with a retinal detachment, an open globe injury, infection inside the eye or raised pressure, when the hemorrhage is long-standing, when it affects both eyes or your only seeing eye, and for children at risk of a lazy eye17. If the retina is attached and the blood is clearing, watching is the usual first plan.
Yes, and the difference is time-sensitive. A young child's brain is still learning to use each eye, so weeks of blocked vision can leave a lasting weak eye. In infants and young children, earlier surgery is considered to reduce the risk of a lazy eye and a shift in focusing power while blood blocks the visual axis20. Have a child with any eye injury examined the same day, even if they say it feels fine.
It is possible, and it is not the most likely outcome. In a small series of severe bleeds after blunt injury, about 21 of every 100 eyes ended at 20/40 or better and about 54 of every 100 stayed worse than 20/2006. Those were the worst bleeds, not average ones. What most protects your vision is within reach: early examination, prompt treatment of any tear, and every follow-up kept.
Not from this injury. The bleeding is local to the eye that was struck. What carries over is protection, since a second injury to your better eye would matter far more. Most serious sports eye injuries could be avoided with appropriate protective eyewear made with shatterproof polycarbonate lenses19. If vision in the injured eye stays reduced, ask about protective lenses for daily wear too.
