What is Diabetic Vitreous Hemorrhage?
Diabetic Vitreous Hemorrhage is a condition where blood leaks into the vitreous humor—the clear gel that fills the inside of the eye—due to complications from diabetes, particularly diabetic retinopathy. This bleeding can obscure vision, cause floaters, or even lead to complete vision loss if severe. It is considered a serious complication that requires medical attention.
What causes Diabetic Vitreous Hemorrhage?
The main cause of Diabetic Vitreous Hemorrhage is proliferative diabetic retinopathy, an advanced stage of diabetic eye disease. In this condition, abnormal blood vessels grow on the surface of the retina due to poor oxygen supply. These fragile vessels are prone to breaking and bleeding into the vitreous.
Other contributing causes include:
- Traction from scar tissue pulling on blood vessels
- Sudden increases in blood pressure
- Eye trauma in diabetic patients
- Poorly controlled diabetes over a long period
What are the symptoms of Diabetic Vitreous Hemorrhage?
Symptoms can vary depending on the amount of bleeding. Common signs include:
- Sudden appearance of floaters (dark spots or squiggly lines)
- Blurred or cloudy vision
- Shadows or a curtain-like effect in the field of vision
- Complete vision loss in severe cases
- Difficulty seeing in low-light conditions
Sometimes, small hemorrhages may resolve on their own, but larger bleeds require treatment.
How is Diabetic Vitreous Hemorrhage diagnosed?
Diagnosis is typically made through a detailed eye examination. Tests may include:
- Dilated eye exam – To observe the retina and detect abnormal blood vessels or bleeding
- Ultrasound – Especially useful when the hemorrhage is dense and the retina can’t be visualized directly
- Optical Coherence Tomography (OCT) – To assess retinal thickness and detect other complications
- Fluorescein angiography – A dye test used to locate the source of bleeding and check for vessel leakage
How is Diabetic Vitreous Hemorrhage treated?
Treatment depends on the severity of the hemorrhage and the underlying cause:
- Observation – Small hemorrhages may resolve on their own over several weeks to months
- Laser photocoagulation – Seals leaking vessels and prevents further bleeding
- Intravitreal injections – Anti-VEGF medications reduce abnormal blood vessel growth
- Vitrectomy – A surgical procedure to remove the blood-filled vitreous and replace it with a clear solution, typically used in severe or persistent cases
Managing blood sugar and treating the root cause (retinopathy) is key in all cases.
What are the complications of Diabetic Vitreous Hemorrhage?
If untreated or recurring, this condition can lead to:
- Permanent vision loss
- Retinal detachment due to traction from scar tissue
- Recurring hemorrhages
- Increased risk of glaucoma
- Difficulty detecting other eye problems due to clouded vision
Early treatment reduces the risk of complications significantly.
How can Diabetic Vitreous Hemorrhage be prevented?
Prevention is centered around effective diabetes management and regular eye care. Steps include:
- Tight control of blood sugar levels
- Regular dilated eye exams, especially for patients with existing retinopathy
- Controlling blood pressure and cholesterol
- Avoiding smoking, which worsens vascular damage
- Treating diabetic retinopathy early to avoid vessel growth and bleeding
When should you see a doctor for Diabetic Vitreous Hemorrhage?
See an eye specialist immediately if you notice:
- Sudden vision changes
- New floaters or flashes of light
- Vision becoming hazy or dark
- Loss of central or peripheral vision
Prompt evaluation can prevent further vision loss and help guide treatment.
Can Diabetic Vitreous Hemorrhage be cured?
While the hemorrhage itself may clear up, the underlying cause—diabetic retinopathy—requires ongoing management. With proper treatment like vitrectomy and laser therapy, vision can often be restored or preserved. Lifelong monitoring is essential for people with diabetes to prevent recurrence.
