Vasoconstrictors
Hello, I have macular hemorrhage and edema in my left eye caused by high myopia.
I am currently undergoing regular intravitreal injections of anti-vascular endothelial growth factor (anti-VEGF).
I have a couple of questions:
1.
Do anti-VEGF injections improve the bleeding, or do they only serve a preventive role? I have received three injections so far, but the results do not seem very promising.
How many injections are typically needed for the symptoms to improve?
2.
What are some ways to care for my affected eye to help stabilize the condition?
Thank you for your professional insights.

Hello, Youzi: 1.
It can improve and prevent bleeding.
Depending on the situation, multiple injections may be necessary at times.
The sensation of pressure may improve only after the blood clot dissipates.

More Info
Vascular inhibitors, particularly anti-VEGF (vascular endothelial growth factor) agents, are commonly used in the treatment of macular hemorrhage and edema, especially in cases related to high myopia. These medications work by inhibiting the growth of abnormal blood vessels in the retina, which can lead to bleeding and swelling. Let's address your questions in detail.
1. Effectiveness of Vascular Inhibitors: Anti-VEGF injections can indeed improve existing hemorrhages and prevent further bleeding. The effectiveness of these injections can vary significantly from patient to patient, depending on the severity of the condition and individual response to the treatment. It is not uncommon for patients to require multiple injections before seeing significant improvement. In some cases, patients may need to undergo treatment every month or as directed by their ophthalmologist, especially if the bleeding persists or if new bleeding occurs. The sensation of "shadowing" or obscured vision may take time to resolve, as it often correlates with the absorption of blood and the healing of the retina. It is essential to maintain regular follow-up appointments with your eye care provider to monitor the condition and adjust treatment as necessary.
2. Eye Care and Maintenance: To stabilize your eye condition and promote overall eye health, consider the following recommendations:
- Regular Eye Exams: Keep up with your scheduled appointments to monitor your condition and adjust treatment as needed.
- Healthy Diet: Incorporate foods rich in antioxidants, such as leafy greens, fish high in omega-3 fatty acids, and fruits, which can help support retinal health.
- Manage Systemic Conditions: If you have conditions like hypertension or diabetes, managing these effectively can reduce the risk of further complications.
- Protect Your Eyes: Wear sunglasses with UV protection when outdoors to shield your eyes from harmful rays, which can exacerbate retinal issues.
- Avoid Smoking: Smoking is detrimental to eye health and can worsen conditions like macular degeneration.
- Limit Screen Time: Take regular breaks from screens to reduce eye strain, which can be particularly important if you are experiencing visual disturbances.
- Follow Medication Guidelines: Adhere strictly to the treatment plan prescribed by your ophthalmologist, including the timing and dosage of any medications.
In conclusion, while vascular inhibitors can significantly aid in the treatment of macular hemorrhage, the response to treatment can vary. It is crucial to maintain open communication with your healthcare provider regarding your treatment progress and any concerns you may have. Regular monitoring and a proactive approach to eye care can help manage your condition effectively. If you notice any sudden changes in your vision or experience new symptoms, seek immediate medical attention.
