Nonsurgical Treatment for Diabetic Vitreous Hemorrhage: When Are Injections Enough?
Non-Surgical Treatment of Diabetic Vitreous Hemorrhage: When Are Injections Enough?
Diabetic retinopathy is one of the most serious chronic complications of diabetes, affecting the tiny blood vessels in the retina, which can lead to bleeding, swelling, and serious changes that threaten vision. While advanced cases often require surgical interventions such as vitrectomy, there are scenarios where diabetic vitreous hemorrhage can be effectively treated without the need for an operating room, relying on intravitreal injection techniques. So, when is this type of treatment sufficient? And what factors determine the course of treatment? Dr. Mahmoud Hassan, a retina and vitreous surgeon and a key contributor to El Mashreq Eye Center in Cairo, answers these questions.
Understanding Diabetic Vitreous Hemorrhage
When blood sugar levels remain high for prolonged periods, the blood vessels in the retina begin to weaken and get damaged. This damage can lead to leakage of fluid or blood into the retina or the vitreous body (the clear gel that fills the eye). This is known as diabetic vitreous hemorrhage, a sign of advanced diabetic retinopathy. Symptoms may include floating spots (floaters), blurred vision, or sudden loss of vision in severe cases.
The Role of Intravitreal Injections in Treating Vitreous Hemorrhage
Intravitreal injection is considered a significant medical breakthrough in the treatment of various retinal diseases, including those caused by diabetes. Specialized medications are injected directly into the vitreous of the eye, with the primary goal of reducing the growth of abnormal blood vessels, absorbing hemorrhage, and reducing swelling (edema) in the macula (the center of vision).
When Are Injections Sufficient?
Intravitreal injections become an effective and sufficient treatment option in the following situations:
- Mild or Limited Hemorrhage: When the hemorrhage in the back of the eye is minor and does not significantly affect the center of vision, injected medications can help absorb the bleeding over time, preventing its escalation.
- Diabetic Macular Edema (DME): DME is a common cause of vision loss in diabetic patients. Injections of anti-vascular endothelial growth factor (Anti-VEGF) drugs, such as Eylea or Vabysmo, or corticosteroids like the Ozurdex implant, are highly effective in reducing this edema and restoring clear vision.
- Early Stages of Proliferative Diabetic Retinopathy (PDR): In some cases where new abnormal blood vessels begin to form but without severe hemorrhage or retinal detachment, injections combined with retinal laser treatment can halt disease progression and protect vision.
- As a Temporary or Initial Alternative: Injections may be used as a first step to reduce bleeding or edema before considering other procedures, or as a long-term treatment to maintain stable condition.
Factors Influencing Treatment Decisions
Dr. Mahmoud Hassan, a key contributor to El Mashreq Eye Center, determines the adequacy of injections as a treatment based on several crucial factors:
- Severity and Location of Hemorrhage: Hemorrhage covering the macula or extending into vital areas of the retina may require faster and more aggressive intervention.
- Presence of Retinal Traction: If the hemorrhage is accompanied by changes that pull on the retina and lead to its detachment, injections alone will not be sufficient, and vitrectomy may be necessary.
- Presence of Macular Edema: As mentioned, injections are the optimal treatment for diabetic macular edema.
- Patient Response to Treatment: Individuals respond differently to injected medications, and some patients may require several injection sessions to maintain results.
- Overall Retinal Condition: The presence of other complications such as retinal vein occlusions or posterior uveitis may affect the treatment plan.
When Is Vitrectomy Surgery Needed?
In some cases, injections are not sufficient, and vitrectomy surgery becomes necessary. These cases include:
- Severe hemorrhage that completely obscures vision and does not respond to injections.
- Presence of retinal traction leading to tractional retinal detachment.
- Extensive formation of fibrous tissue or abnormal blood vessels.
- Failure of injection or laser treatment to control the condition.
The decision to opt for surgery or rely solely on injections is a precise medical one based on a comprehensive evaluation of the condition, which Dr. Mahmoud Hassan and his team at El Mashreq Eye Center are keen to provide.
Importance of Regular Follow-up
Regardless of the type of treatment chosen, whether intravitreal injections or surgery, regular follow-up with a specialized ophthalmologist in retinal diseases is critically important. Diabetes is a chronic disease that requires continuous management, and the retina also needs regular monitoring for early detection of any new changes or complications. Regular eye exams, especially for diabetic patients, help detect problems in their early stages before they worsen and permanently affect vision.
Understanding when injections are sufficient for treating diabetic vitreous hemorrhage is key to preserving eye health and vision. Advances in intravitreal injection techniques offer effective and non-surgical treatment options for many cases, reducing the need for surgical interventions and improving visual outcomes for patients.

The price of intravitreal injection (IVI) in Egypt for 2026 starts from approximately 7,000 EGP. Injection prices vary based on the type of medication used, such as Eylea / Lucentis injections which cost approximately 9,000 EGP, or Vabysmo injections which cost approximately 11,000 EGP, or Eylea HD injections which cost approximately 12,000 EGP, or Ozurdex implant injections which cost approximately 27,000 EGP. These prices are approximate and depend on the individual patient's condition and complexity.
