Causes & Risk Factors

Several factors can contribute to Vitreous Hemorrhage.

The most common cause of vitreous hemorrhage is diabetic retinopathy, which accounts for about one-third of all cases.

The most common cause of vitreous hemorrhage is diabetic retinopathy, which accounts for about one-third of all cases. High blood sugar levels damage the tiny blood vessels in the retina, making them weak and prone to bleeding. As diabetes progresses, abnormal new blood vessels can grow on the retina's surface. These vessels are fragile and can rupture easily, sending blood into the vitreous cavity.

Retinal tears and detachments represent another major cause of vitreous bleeding.

Retinal tears and detachments represent another major cause of vitreous bleeding. As we age, the vitreous gel naturally shrinks and can pull away from the retina. Sometimes this pulling creates a tear in the retinal tissue, which can cause bleeding. Eye trauma from accidents, sports injuries, or blunt force can also damage blood vessels and lead to hemorrhage. Even seemingly minor impacts can cause bleeding if they occur at the wrong angle or with sufficient force.

Risk Factors

Diabetes, especially with poor blood sugar control
High blood pressure (hypertension)
Age over 50 years
Previous eye surgery or laser treatment
Family history of retinal problems
Severe nearsightedness (myopia)
Eye trauma or injury history
Blood clotting disorders
Sickle cell disease or other blood disorders
Previous vitreous hemorrhage

Diagnosis

How healthcare professionals diagnose Vitreous Hemorrhage:

1
When you visit an eye doctor with symptoms of vitreous hemorrhage, they'll start with a comprehensive eye examination.
When you visit an eye doctor with symptoms of vitreous hemorrhage, they'll start with a comprehensive eye examination. The doctor will dilate your pupils with eye drops to get a clear view of the inside of your eye. Using specialized instruments like an ophthalmoscope or slit lamp, they can directly observe blood in the vitreous cavity and assess the extent of bleeding. In cases where the bleeding is dense, ultrasound imaging may be necessary to evaluate the retina behind the blood.
2
The doctor will also check your vision, eye pressure, and examine both eyes thoroughly.
The doctor will also check your vision, eye pressure, and examine both eyes thoroughly. Blood tests might be ordered to check for diabetes or blood clotting problems if these conditions haven't been previously diagnosed. Fluorescein angiography, where dye is injected into your arm and photographed as it travels through eye blood vessels, can help identify the source of bleeding and guide treatment decisions.
3
Determining the underlying cause is crucial for proper treatment.
Determining the underlying cause is crucial for proper treatment. The examination will focus on identifying diabetic retinopathy, retinal tears, or other conditions that might have triggered the bleeding. Your medical history, including any recent eye trauma or existing health conditions, provides important clues. In some cases, you may need to return for follow-up examinations as the blood clears to better assess the retina and determine if additional treatment is needed.

Complications

The most significant complication of vitreous hemorrhage is permanent vision loss, which can occur if the underlying retinal condition isn't properly treated or if the hemorrhage is so severe that it damages retinal tissue.
Recurrent bleeding episodes are common, particularly in people with diabetic retinopathy or other chronic retinal conditions.
Each episode can potentially cause additional vision loss and may require more aggressive treatment.
In some cases, the blood in the vitreous can form scar tissue or membranes that pull on the retina, potentially causing retinal detachment.
This secondary complication requires immediate surgical treatment to prevent permanent vision loss.
Ghost cell glaucoma is another possible complication where old blood cells clog the eye's drainage system, leading to increased eye pressure.
While this is relatively rare, it can cause additional vision problems if not promptly treated with medications or surgery.

Prevention

Preventing vitreous hemorrhage focuses primarily on managing underlying health conditions and protecting your eyes from injury.
For people with diabetes, maintaining good blood sugar control is the most effective prevention strategy.
Regular hemoglobin A1C testing, following a diabetes-appropriate diet, taking medications as prescribed, and monitoring blood glucose levels can significantly reduce the risk of diabetic retinopathy progressing to the point of causing bleeding.
Regular comprehensive eye exams are essential, especially for people with diabetes or high blood pressure.
Early detection and treatment of retinal problems can prevent them from progressing to vitreous hemorrhage.
The American Diabetes Association recommends annual eye exams for most people with diabetes, though some may need more frequent monitoring.
Protecting your eyes from trauma is equally important.
Wear appropriate safety eyewear during sports, work activities, or any situation where eye injury could occur.
This includes safety glasses, goggles, or face shields depending on the activity.
Managing blood pressure through diet, exercise, and medication when necessary also helps maintain healthy blood vessels throughout the body, including in the eyes.
If you have high myopia or a family history of retinal problems, discuss with your eye doctor whether you need more frequent monitoring or specific precautions.

Treatment Approaches

Treatment for vitreous hemorrhage depends on the severity of bleeding and the underlying cause.

Treatment for vitreous hemorrhage depends on the severity of bleeding and the underlying cause. For mild cases where vision isn't significantly affected, doctors often recommend a watch-and-wait approach. The blood may clear naturally over several weeks to months as the eye's normal processes gradually absorb it. During this time, patients are advised to sleep with their head elevated to help blood settle away from the central visual field.

When the underlying cause is diabetic retinopathy, laser photocoagulation or anti-VEGF injections may be used to treat abnormal blood vessels and prevent future bleeding.

When the underlying cause is diabetic retinopathy, laser photocoagulation or anti-VEGF injections may be used to treat abnormal blood vessels and prevent future bleeding. These medications, including ranibizumab and bevacizumab, help reduce the growth of problematic blood vessels. For retinal tears, laser surgery or cryotherapy can seal the tear and prevent further bleeding.

SurgicalMedication

Vitrectomy surgery becomes necessary when bleeding is severe, vision is significantly impaired, or the blood doesn't clear after several months.

Vitrectomy surgery becomes necessary when bleeding is severe, vision is significantly impaired, or the blood doesn't clear after several months. During this procedure, surgeons remove the blood-filled vitreous gel and replace it with a clear solution. The surgery also allows direct treatment of retinal problems that caused the bleeding. Recovery typically takes several weeks, and vision improvement can continue for months as the eye heals.

Surgical

Recent advances include the use of intravitreal medications that can be injected directly into the eye to treat specific causes of bleeding.

Recent advances include the use of intravitreal medications that can be injected directly into the eye to treat specific causes of bleeding. These treatments are less invasive than surgery and can be performed in the doctor's office. Anti-VEGF therapy has revolutionized treatment for many retinal conditions that cause vitreous hemorrhage, offering hope for better outcomes and reduced recurrence rates.

Living With Vitreous Hemorrhage

Living with vitreous hemorrhage requires patience and adaptation, especially during the healing process. Many people find that symptoms are more noticeable in certain lighting conditions, so adjusting your environment can help. Use good lighting when reading or doing detailed work, and consider using magnifying devices if vision is impaired. Avoid activities that could increase eye pressure, such as heavy lifting or straining, until your doctor gives clearance.

Regular follow-up appointments are crucial for monitoring healing and watching for signs of recurrent bleeding.Regular follow-up appointments are crucial for monitoring healing and watching for signs of recurrent bleeding. Keep a symptom diary noting any changes in vision, new floaters, or flashing lights, as these could indicate new bleeding or other complications. If you have diabetes, maintaining excellent blood sugar control becomes even more critical to prevent future episodes.

Emotional support is often needed, as vision problems can significantly impact daily life and independence.Emotional support is often needed, as vision problems can significantly impact daily life and independence. Consider connecting with support groups for people with vision loss or retinal conditions. Many communities offer resources for people with visual impairments, including transportation services and adaptive technologies. With proper treatment and monitoring, many people with vitreous hemorrhage can maintain functional vision and continue their normal activities, though some lifestyle adjustments may be necessary.

Frequently Asked Questions

Will my vision return to normal after vitreous hemorrhage?

Vision recovery varies greatly depending on the cause and severity of bleeding. Mild cases often clear completely within weeks to months, while severe cases may result in permanent vision changes. Early treatment of the underlying cause improves the chances of good vision recovery.

Can I drive with vitreous hemorrhage?

You should not drive if your vision is significantly impaired by vitreous hemorrhage. Check with your eye doctor about when it's safe to resume driving, as this depends on your specific vision level and local legal requirements.

Is vitreous hemorrhage an emergency?

Sudden vision loss or large amounts of new floaters should be evaluated promptly, ideally within 24 hours. While not always a true emergency, quick evaluation can identify serious conditions that need immediate treatment.

Can stress or physical activity cause vitreous hemorrhage?

Stress itself doesn't directly cause vitreous hemorrhage, but sudden increases in blood pressure from heavy lifting or straining can potentially trigger bleeding in people with weak retinal blood vessels. Moderate exercise is generally safe and beneficial.

Will I need surgery for vitreous hemorrhage?

Many cases clear on their own without surgery. Vitrectomy surgery is typically reserved for severe cases where vision is significantly impaired or bleeding doesn't clear after several months of observation.

Can vitreous hemorrhage happen in both eyes at once?

While possible, especially in people with diabetes or blood disorders, vitreous hemorrhage more commonly affects one eye at a time. Having it in one eye does increase the risk for the other eye, particularly if underlying conditions aren't well controlled.

Are there foods I should avoid with vitreous hemorrhage?

There are no specific foods to avoid, but if you have diabetes, following a diabetes-appropriate diet is crucial for preventing future episodes. Maintaining stable blood sugar levels helps protect retinal blood vessels.

How long does it take for blood to clear from the eye?

Small amounts of blood may clear within weeks, while larger hemorrhages can take several months. The vitreous has limited blood flow, so absorption is slower than in other parts of the body.

Can I wear contact lenses with vitreous hemorrhage?

Contact lens wear is generally safe with vitreous hemorrhage since the bleeding is inside the eye, not on the surface. However, check with your eye doctor, especially if you're using eye drops or planning surgery.

Does vitreous hemorrhage always come back?

Recurrence depends on the underlying cause. People with well-controlled diabetes or successfully treated retinal tears have lower recurrence rates than those with ongoing retinal disease. Regular monitoring and treatment of underlying conditions help prevent future episodes.
