Clinical information guide
Vitreous hemorrhage is a clinical condition characterized by the extravasation (leakage) of blood into the vitreous humor—the transparent, jelly-like substance that fills the posterior two-thirds of the eye. This gel is normally clear to allow light to pass through to the retina (the light-sensitive tissue at the back of the eye). When blood enters this space, it scatters light, leading to symptoms ranging from mild 'floaters' to complete vision loss. Pathophysiologically, this occurs when a retinal blood vessel is torn or when abnormal, fragile new blood vessels (neovascularization) leak due to underlying systemic or ocular disease.
Vitreous hemorrhage is one of the most common causes of sudden vision loss. According to research published in the Journal of Ophthalmology (2022), the incidence is estimated at approximately 7 cases per 100,000 people per year. While it can affect individuals of any age, it is most prevalent in adults over age 50, primarily due to the increased frequency of diabetic complications and age-related eye changes. Data from the National Eye Institute (NEI, 2023) indicates that diabetic retinopathy remains the leading cause, accounting for nearly 31.5% to 54% of all cases in the United States.
Vitreous hemorrhage is typically classified based on its underlying mechanism:
The impact of a vitreous hemorrhage can be profound, often causing immediate anxiety due to the sudden nature of vision impairment. Patients may struggle with tasks requiring depth perception and central clarity, such as driving, reading, or operating machinery. In chronic or recurrent cases, the persistent presence of floaters can lead to significant psychological distress and a decreased quality of life. Furthermore, if the underlying cause is not managed, it can lead to permanent vision loss, affecting an individual's independence and ability to work.
Detailed information about Vitreous Hemorrhage
The earliest indicator of a vitreous hemorrhage is often the sudden appearance of 'floaters'—small dark spots, streaks, or cobweb-like shapes that drift across the field of vision. Unlike standard floaters associated with aging, these may appear more numerous or be accompanied by a reddish or dark tint to the vision.
Answers based on medical literature
Vitreous hemorrhage is not a disease itself but a symptom of an underlying condition, and in most cases, the blood can be cleared or will resolve on its own. While the hemorrhage can be 'cured' through observation or surgery, the underlying cause, such as diabetic retinopathy, requires lifelong management to prevent recurrence. Modern surgical techniques like vitrectomy have a high success rate in restoring vision for those whose blood does not clear naturally. However, the final visual outcome depends heavily on whether the retina was damaged during the bleeding event. Therefore, while the acute bleeding can be resolved, ongoing care is essential for long-term ocular health.
Yes, many mild cases of vitreous hemorrhage clear spontaneously as the body naturally reabsorbs the blood over several weeks or months. During this time, the blood typically settles to the bottom of the eye, which may result in a gradual improvement in central vision. Doctors often recommend 'watchful waiting' for 4 to 6 weeks if the retina is known to be healthy and attached. However, if the blood is very dense or if there is an underlying retinal tear, the blood may not clear fast enough to prevent complications. In such cases, surgical intervention is usually recommended to restore vision and treat the source of the leak.

In rare instances, if the hemorrhage is associated with significant inflammation or high intraocular pressure (glaucoma), patients might experience mild ocular discomfort or a feeling of fullness in the eye. However, the hemorrhage itself is typically painless.

Symptoms are generally consistent across genders. In younger patients, vitreous hemorrhage is more likely to be associated with trauma or sickle cell retinopathy, whereas in older populations, it is frequently tied to posterior vitreous detachment (PVD) or complications from long-standing diabetes.
Vitreous hemorrhage is caused by the rupture of blood vessels within or near the vitreous gel. Research published in Ophthalmology suggests three primary mechanisms: damage to normal vessels (trauma or retinal tears), the rupture of abnormal new vessels (neovascularization), or the extension of blood from other areas (such as a subretinal hemorrhage). When the retina is deprived of oxygen (ischemia), it releases growth factors that trigger the growth of fragile new vessels that bleed easily.
According to the Centers for Disease Control and Prevention (CDC, 2023), individuals with diabetes are at the highest risk. Approximately 1 in 3 people with diabetes over age 40 have some sign of diabetic retinopathy. Other high-risk groups include those with high myopia (severe nearsightedness), as their retinas are thinner and more prone to tearing, and individuals on anticoagulant (blood-thinning) medications.
Prevention focuses on managing underlying systemic conditions. The American Academy of Ophthalmology (AAO) recommends annual dilated eye exams for all diabetic patients. Evidence-based strategies include maintaining an A1c level below 7%, controlling blood pressure, and wearing ANSI-approved safety goggles during sports or manual labor to prevent ocular trauma.
The diagnostic journey begins with a comprehensive eye examination. Because the blood can block the doctor's view of the retina, specialized imaging is often required to determine the source of the bleeding and to rule out a retinal detachment.
Diagnosis is confirmed by the clinical presence of red blood cells within the vitreous cavity during a microscopic exam. The ICD-10 code H43.1 is applied when the hemorrhage is the primary clinical finding requiring management.
Healthcare providers must distinguish vitreous hemorrhage from other conditions, such as:
The primary goals of treatment are to identify and treat the source of the bleeding, clear the blood from the visual path, and prevent permanent vision loss or complications like glaucoma. Successful treatment is measured by the stabilization of the retina and the restoration of visual acuity.
According to clinical guidelines from the American Academy of Ophthalmology (2024), the initial approach depends on the cause. If the retina is intact (confirmed by ultrasound), 'watchful waiting' is often the first step. Patients are advised to sleep with the head of the bed elevated to allow gravity to settle the blood at the bottom of the eye.
If the blood does not clear on its own within several weeks to months, or if a retinal tear is detected, surgical intervention is required. Laser photocoagulation is often used in combination with injections to 'cauterize' leaking vessels and prevent future bleeding.
Monitoring involves frequent follow-up exams (every 1–4 weeks initially) to ensure the blood is clearing and the retina remains attached. If a vitrectomy is performed, recovery typically takes 2–6 weeks.
> Important: Talk to your healthcare provider about which approach is right for you.
While diet cannot directly clear a hemorrhage, managing the underlying cause is vital. For diabetic patients, a low-glycemic diet is essential. Research in The American Journal of Clinical Nutrition suggests that diets rich in antioxidants (Lutein and Zeaxanthin) found in leafy greens may support overall retinal health.
During an active hemorrhage, patients are typically advised to avoid strenuous activity, heavy lifting, or bending over, as these can increase venous pressure in the head and potentially trigger more bleeding. Light walking is generally acceptable, but consult your surgeon for specific restrictions.
Sleep with the head of the bed elevated at a 30-to-45-degree angle. This allows the blood to settle at the bottom of the vitreous cavity, which may clear the central vision more quickly and allow the ophthalmologist to see the retina more clearly during exams.
Vision loss is a significant stressor. Evidence-based techniques such as mindfulness-based stress reduction (MBSR) can help patients cope with the anxiety of fluctuating vision. Support groups for the visually impaired can also provide emotional relief.
There is no strong clinical evidence that herbal supplements like bilberry or ginkgo biloba can treat vitreous hemorrhage. Patients should exercise caution, as some supplements (like high-dose Vitamin E or Ginkgo) may have mild blood-thinning effects, which could theoretically worsen bleeding.
The prognosis for vitreous hemorrhage is generally good, provided the underlying cause is treated promptly. According to a study in Clinical Ophthalmology (2023), approximately 60% to 70% of cases caused by PVD or minor trauma resolve spontaneously with good visual recovery. However, cases associated with diabetic retinopathy or retinal detachment have a more guarded prognosis and may require surgery to prevent permanent blindness.
Patients require lifelong monitoring of the retina, especially if the cause was diabetes or a retinal vein occlusion. Regular dilated exams are necessary to catch new vessel growth early.
Most patients return to normal activities once the blood clears. Utilizing low-vision aids (magnifiers, high-contrast screens) during the recovery phase can help maintain independence.
Contact your ophthalmologist immediately if you notice a sudden increase in floaters, a new shadow in your vision, or if your vision stops improving and starts to decline again.
A vitreous hemorrhage should be treated as an urgent medical situation because it often signals a serious underlying problem like a retinal tear or detachment. While the bleeding itself is not usually painful, the conditions causing it can lead to permanent blindness if not addressed within hours or days. An immediate dilated eye exam and often an ultrasound are necessary to ensure the retina is still properly attached to the back of the eye. Delaying treatment can allow scar tissue to form or lead to more complex retinal issues. Therefore, any sudden onset of floaters or vision loss warrants an immediate trip to an eye specialist.
The most frequent cause of vitreous hemorrhage in adults is proliferative diabetic retinopathy, a complication of diabetes where high blood sugar damages retinal vessels. These damaged vessels release growth factors that cause fragile, abnormal new vessels to grow across the retina and into the vitreous. These new vessels lack the structural integrity of normal vessels and can rupture easily, even without trauma. Other common causes include posterior vitreous detachment (PVD) and retinal tears, which occur as the vitreous gel shrinks with age. In younger populations, eye trauma is a more frequent cause of the condition.
Generally, patients with an active vitreous hemorrhage are advised to avoid strenuous exercise, heavy lifting, and high-impact activities. These actions can increase the pressure in the blood vessels of the head and eye, potentially causing further bleeding or preventing existing clots from stabilizing. Most ophthalmologists recommend sticking to light walking and avoiding any activity that requires bending over at the waist. It is also important to avoid rubbing the eye, as this can cause further mechanical stress on the vessels. Always consult with your specific eye surgeon or doctor before resuming any exercise routine after a hemorrhage.
The time it takes for a vitreous hemorrhage to clear varies significantly depending on the volume of blood and the underlying cause. Small amounts of blood may resolve within 2 to 4 weeks, while more significant hemorrhages can take several months to clear completely. Because blood in the vitreous clears at a rate of approximately 1% per day, patience is often required during the observation period. If the blood has not significantly cleared within 2 to 3 months, or if it is obstructing necessary treatment for the retina, a vitrectomy is usually performed. Your doctor will use regular exams to monitor the rate of clearance.
Yes, systemic hypertension (high blood pressure) is a significant risk factor for several eye conditions that lead to vitreous hemorrhage. Chronic high blood pressure can lead to retinal vein occlusion, where a 'stroke' occurs in the eye's veins, causing them to leak blood into the vitreous. It also exacerbates the damage caused by diabetes, making retinal vessels more prone to rupture. Controlling blood pressure is a key component of preventing both the initial occurrence and the recurrence of bleeding. Patients with sudden vision loss should have their blood pressure checked as part of their initial medical evaluation.
Vitreous hemorrhage itself does not usually cause permanent blindness, but the underlying condition causing the bleed can. If the blood is caused by a retinal detachment that goes untreated, the light-sensitive cells of the retina can die, leading to irreversible vision loss. Additionally, if blood remains in the eye for a very long time, the iron in the blood can become toxic to the retina, a condition known as hemosiderosis. However, with modern diagnostic tools like B-scan ultrasound and surgical procedures like vitrectomy, most patients can avoid permanent blindness. Early intervention is the most critical factor in preserving long-term sight.
There are no proven natural remedies or supplements that can effectively clear blood from the vitreous humor. While some people suggest bilberry or vitamin supplements for general eye health, these cannot fix a ruptured blood vessel or reabsorb a hemorrhage. In fact, some natural supplements like ginger, ginkgo, and high-dose vitamin E have blood-thinning properties that might theoretically increase the risk of further bleeding. The most effective 'natural' approach is gravity; sleeping with your head elevated helps the blood settle. Beyond that, medical management of blood sugar and blood pressure is the only evidence-based way to support recovery naturally.
Surgery is not always necessary, but it is required in specific circumstances. If an ultrasound reveals that the retina is torn or detached, surgery (vitrectomy or laser) is usually performed urgently to save the vision. Surgery is also recommended if the blood is very dense and shows no signs of clearing after several weeks, especially in diabetic patients who need laser treatment that the blood is blocking. For many others, the blood will clear on its own with simple observation. Your ophthalmologist will weigh the risks of surgery against the benefits of clearing the vision more quickly based on your specific case.
