Retinal Injections: When Are They the Right Option?

Last Updated: 13/05/2026

Retinal injections are among the treatments used for certain retinal diseases, especially conditions associated with fluid leakage or abnormal blood vessel growth inside the eye. A doctor may recommend them in cases such as retinal edema, diabetic retinopathy, retinal vein occlusion, or some conditions affecting the macula.

Eye injections for retinal treatment aim to deliver medication directly into the eye at a dose determined by the doctor based on the diagnosis. Careful follow-up is needed to measure response and reduce the risk of vision deterioration. Medical references explain that intravitreal injections are used to deliver medications such as anti-VEGF agents or some types of steroids to treat specific retinal diseases.

What Are Retinal Injections?

Retinal injections are a medical procedure in which an ophthalmologist places medication inside the vitreous body, the gel-like substance in the back of the eye. The goal is to deliver the medication close to the retina and macula, instead of relying only on eye drops or general medications that may not be sufficient in some cases.

Although the idea of an eye injection may worry some patients, the procedure is usually performed after applying local anesthesia to the eye using drops or gel to reduce discomfort.

Doctors at Magrabi Hospitals explain that the decision to use injections is not based on symptoms alone. It is made after examining and imaging the retina, identifying the type of problem, and assessing how much it affects vision.

 

Why Are Retinal Injections Used?

A patient may need retinal injections when changes occur inside the retina, causing swelling, bleeding, or abnormal blood vessel growth.

Conditions that may require eye injections include:

• Diabetic retinopathy: This occurs when the small blood vessels in the retina are affected by high blood sugar levels over long periods. It may lead to retinal edema or bleeding inside the eye. The Saudi Ministry of Health states that diabetic retinopathy is one of the leading causes of vision loss among people with diabetes, and that early detection and treatment significantly reduce the risk of blindness.
• Retinal edema or macular edema: This occurs when fluid accumulates in the macula, causing blurred vision or difficulty seeing fine details.
• Retinal vein occlusion: This may lead to fluid leakage or bleeding inside the retina. The patient may need anti-VEGF injections or other treatments depending on the case.
• Wet age-related macular degeneration: Abnormal blood vessels may appear under the retina and cause leakage that affects the macula.
• Inflammation or infection inside the eye in specific cases: Some anti-infective medications may be injected inside the eye when the doctor decides this is necessary.

 

What Are the Symptoms of Conditions That May Require Retinal Injections?

Some retinal diseases may not cause clear symptoms in their early stages. For this reason, patients should not wait until vision becomes weak before seeing a doctor, especially patients with diabetes. Mayo Clinic explains that diabetic retinopathy may begin without symptoms, then later cause symptoms such as blurred vision, floaters, or loss of areas in the visual field as the condition progresses.

Symptoms that require retinal examination include:

• Blurred or hazy vision.
• Spots or thread-like floaters in front of the eye.
• Difficulty reading or seeing fine details.
• Changes in the size or shape of objects when looking at them.
• Weak central vision or a dark spot in the center of vision.
• Sudden or gradual vision deterioration.
• Light flashes or a sudden increase in floaters.

These symptoms do not always mean that the patient needs injections. However, they do mean that retinal examination is important to identify the cause.

 

How Is the Need for Retinal Injections Diagnosed?

Diagnosis usually begins with the doctor asking about symptoms, medical history, diabetes or high blood pressure, and the medications the patient uses. After that, the doctor performs a comprehensive eye examination and may use drops to dilate the pupil and view the retina clearly.

Diagnostic steps may include:

• Fundus examination: This helps the doctor see the retina, blood vessels, and macula.
• Optical coherence tomography, or OCT: This shows retinal thickness and the presence of fluid or edema.
• Fluorescein angiography: This helps identify areas of leakage, blockage, or abnormal blood vessels.
• Vision and eye pressure measurement: This helps assess the general impact of the condition and monitor any associated factors.

Doctors at Magrabi emphasize that accurate diagnosis is the foundation before determining whether the patient needs injections, laser treatment, observation only, or another intervention.

What Is the Difference Between Eye Injections for Retinal Treatment, Laser, and Surgery?

Retinal treatment varies depending on the type of problem, its location, and how much it affects the macula. The doctor may recommend eye injections for retinal treatment in cases of edema or abnormal blood vessel growth. Laser or surgery may be more suitable in other cases, such as severe bleeding or traction on the retina.

Treatment Method	When Is It Used?	Purpose	Important Notes
Eye injections for retinal treatment	In cases such as retinal edema, diabetic retinopathy, retinal vein occlusion, and some macular problems	To reduce fluid or limit abnormal blood vessel growth inside the eye	The patient may need more than one session. The doctor determines the number of injections based on retinal response
Laser	In some cases of vascular leakage, diabetic retinopathy, or weak areas in the retina	To stabilize certain retinal areas, reduce leakage, or prevent some complications from progressing	It is not suitable for all cases. It may be used alone or with injections depending on the diagnosis
Surgery	In advanced cases such as severe vitreous bleeding, retinal detachment, or traction on the retina	To treat more complex problems that injections or laser alone cannot manage	The doctor decides whether surgery is needed after careful examination and retinal imaging

Doctors at Magrabi Hospitals explain that choosing between retinal injections, laser, and surgery does not depend only on the name of the disease. It depends on the condition of the retina, the degree of vision impairment, and the test results. Therefore, the treatment plan may differ from one patient to another, even when the diagnosis seems similar.

 

What Factors Determine Retinal Injection Cost?

Retinal injection cost varies from one patient to another depending on the type of medication used, the number of sessions recommended by the doctor, the condition of the retina, and the tests needed before injection, such as retinal imaging or macular examination. Therefore, an accurate cost cannot be determined without a medical examination, because the plan for retinal treatment with injections may be short in some cases and may require repeated follow-up in others, such as diabetic retinopathy or retinal edema.

Doctors at Magrabi Hospitals explain that knowing the price alone is not enough to choose the treatment. The most important factors are identifying the cause of the problem, how much it affects vision, and the most suitable type of injection for the case. After the examination, the doctor can explain the expected treatment plan, number of visits, and cost more clearly.

 

What Instructions Are Recommended After Eye Injections?

After the retinal injection procedure, it is important to follow the doctor’s instructions carefully. The doctor may allow the patient to return to normal daily activities, but it is important to avoid touching the eye or exposing it to sources of contamination on the day of the injection.

General instructions the doctor may recommend include:

• Do not rub the eye after the procedure.
• Use eye drops only if prescribed by the doctor.
• Avoid swimming or allowing unclean water to enter the eye for the period specified by the doctor.
• Inform the doctor immediately if there is increasing pain or clear vision weakness.
• Attend the follow-up appointment, because some cases require repeated injections.

The American Society of Retina Specialists notes that the need for repeated injections is often determined after clinical examination and tests such as OCT or angiography.

 

How Can Retinal Diseases Be Prevented?

Not all retinal diseases can be prevented, but the risk of some complications can be reduced, and many problems can be detected early. The most important step is regular follow-up, especially for patients with diabetes and high blood pressure.

Practical tips to maintain retinal health include:

• Control blood sugar according to the doctor’s plan.
• Monitor blood pressure and cholesterol.
• Have regular eye examinations, especially for patients with diabetes.
• Stop smoking.
• See a doctor if any change in vision occurs.
• Do not use eye drops or medications without a prescription.
• Keep follow-up visits after injections or laser treatment.

Doctors at Magrabi indicate that early follow-up helps the doctor choose the appropriate treatment before the problem affects the macula more significantly.

 

When Should You See a Doctor?

Doctors at Magrabi Hospitals recommend seeing a doctor if:

• Blurred vision continues or worsens over time.
• Spots or thread-like floaters appear suddenly in front of the eye.
• The patient notices weak central vision or difficulty reading.
• Sudden vision deterioration occurs.
• Light flashes or a dark curtain appears in the field of vision.
• The patient has diabetes, even if there are no clear symptoms.
• Severe pain, clear redness, or vision deterioration appears after an eye injection.
• Symptoms affect driving, work, phone use, or daily activities.

Early examination helps the doctor evaluate the retina accurately and determine whether the condition needs monitoring, retinal injections, laser, or another suitable treatment.

 

Frequently Asked Questions

When Does a Patient Need Retinal Injections?

A patient may need retinal injections if examination shows edema, abnormal blood vessels, bleeding, or changes affecting the macula. The decision depends on the doctor’s examination and retinal imaging, not on symptoms alone.

Are Retinal Injections Painful?

Retinal injections are usually not clearly painful because the doctor uses local anesthesia for the eye. The patient may feel mild pressure or slight discomfort during the procedure, and temporary irritation may occur after the injection.

How Many Times Is the Eye Injected?

The number of injections varies depending on the disease and retinal response to treatment. Some patients may need monthly injections at the beginning, then sessions may become less frequent later. The doctor determines the schedule after examination and follow-up.

What Is the Difference Between Injections and Lasers?

Injections deliver medication inside the eye to reduce leakage or abnormal blood vessel growth. Laser is used to treat specific areas of the retina or reduce leakage. Some patients may need one treatment or both, depending on the diagnosis.

Does Vision Improve After a Retina Needle Injection?

Vision may improve in some cases. In other cases, the goal may be to stabilize the condition and reduce deterioration. The result depends on the cause of the disease, duration of the condition, state of the macula, and commitment to follow-up.

When Should I Be Concerned After an Eye Injection?

You should contact the doctor immediately if severe pain, clear vision deterioration, increasing redness, strong sensitivity to light, or a significant increase in floaters occurs after the injection. These signs require prompt evaluation.
