Intravitreal drug administration in Moscow
Some retinal diseases require precise delivery of medication directly into the eye rather than general treatment. In such cases, intravitreal injections are used—a modern method in which medication is injected directly into the vitreous. At the K+31 clinic, we follow current protocols, use modern medications, and thoroughly explain each step of therapy to patients. It's important for us not only to perform the procedure but also to provide a clear treatment plan, vision monitoring, and post-injection follow-up.

What medications are used?
Different groups of medications are used for treatment. Most commonly, anti-VEGF therapy and anti-inflammatory injections are used.
The choice depends on the diagnosis. For wet AMD and vascular disorders, the treatment goal is different for inflammatory diseases. This is why intravitreal drug administration in Moscow should always be performed after diagnosis and examination by a specialist.
We always explain to the patient why a specific medication has been chosen and what results can be expected from the therapy.
What conditions is it prescribed for?
The main goal of the procedure is to treat retinal diseases that require localized treatment of the eye tissue.
Indications for intravitreal drug administration:
- Wet AMD - age-related macular degeneration
- Diabetic macular edema
- Macular edema following vascular disorders
- Inflammatory eye diseases
- Other conditions requiring precise delivery of the active ingredient
The procedure is also used for conditions such as retinal vein thrombosis, chronic macular edema, and some complications of diabetes.
When are intravitreal injections really needed?
Not all patients require this therapy. The decision on treatment is made only by an ophthalmologist after examination and assessment of the retina.
Main Indications
Intravitreal injections are most often prescribed for conditions associated with retinal vascular damage and fluid accumulation in the macula.
Main indications include:
- Wet AMD
- Diabetic macular edema
- Vascular diseases of the retina
- Consequences of vascular thrombosis
- Chronic macular edema
In some cases, therapy is administered in a course. The frequency of administration depends on the diagnosis and the ocular tissue response to the drug.
When is the procedure postponed?
There are situations in which treatment is temporarily postponed. For example, in cases of severe eye inflammation, infectious diseases, or the patient's unstable general condition.
The doctor also evaluates the presence of contraindications and possible risks. It is not recommended to independently choose a medication or try to change the therapy.
Why is an accurate diagnosis important before treatment?
Before starting therapy, we perform a retinal examination and assess the condition of the macula. We use modern equipment, including OCT (optical coherence tomography).
This examination helps determine the cause of vision loss, assess the thickness of the retina, and understand the activity of the disease.
“We always select an intravitreal drug after a diagnosis and explain each step to the patient. Our goal is not just to administer an injection, but to ensure a clear treatment plan, monitoring of results, and safety at every step.”
How the procedure is carried out at the K+31 clinic
For many patients, the main fear is associated with the injection itself. Therefore, we explain in detail how the procedure works, what sensations are considered normal, and why the treatment is only performed in a medical setting.
Preparation for intravitreal injection
Before the procedure, an examination and re-evaluation of the eye's condition are performed. The doctor clarifies any complaints, reviews the examination results, and rules out any contraindications.
We work exclusively in sterile conditions. Operating rooms are disinfected in accordance with international protocols. Antiseptic solutions and local anesthetic drops are used before injections.
Stages of injection
During the procedure, an injection is administered into the vitreous through a small access point. The intravitreal injection itself takes only a short time.
The patient is in a comfortable position, and the doctor monitors all stages of the procedure. After the solution is administered, the eye is examined and monitored.
All procedures are performed in a sterile room, following current protocols and clinical guidelines.
What does the patient feel during the procedure?
Due to the use of local anesthesia, there is usually no significant pain. The patient may feel pressure, mild discomfort, or a brief foreign body sensation.
After the procedure, eye redness, tearing, or irritation may sometimes occur. These symptoms usually subside gradually.
General information
Advantages of therapy
Precise targeting of the disease
The main advantage of this method is local drug delivery. The medication directly reaches the retina and macula, where the pathological process is developing.
This approach is especially important for diseases that require a high concentration of the active ingredient inside the eye.
Minimal systemic load
Compared to systemic therapy, the drug has less impact on other organs and tissues of the body.
| Method | Where the drug is delivered | When it is prescribed | Advantages | Limitations |
|---|---|---|---|---|
| Intravitreal | Directly into the vitreous | Diseases of the retina, macula | Maximum local concentration, minimum systemic effects | Requires sterility and physician experience |
| Systemic therapy | Whole body | Systemic inflammatory processes | Effect on the whole body | High load, risk of side effects Effects |
Monitoring results and progress
After treatment, it is important to evaluate retinal changes and vision progress. Therefore, the patient undergoes regular vision monitoring and follow-up examinations.
In some cases, multiple treatments are required. The decision to continue therapy is made after a repeat diagnosis.

What is intravitreal injection and how does it work?
Intravitreal drug administration is an injection into the vitreous body of the eye. This approach helps deliver the drug precisely to the affected area and create the necessary concentration of the substance near the retina and macula.
This method is actively used in modern ophthalmology for diseases associated with retinal vascular damage, macular edema, and impaired ocular tissue nutrition. Unlike systemic therapy, the drug acts locally and has virtually no significant impact on the entire body.
How the procedure works
After administration, the drug begins to work directly inside the eye. This is especially important for diseases that affect the retina and the central area of vision—the macula.
Some pathologies cause abnormal blood vessels to form in the eye or macular edema to develop. This leads to impaired tissue nutrition and decreased vision. In such cases, anti-VEGF therapy is used to help control the growth of abnormal vessels and reduce swelling.
Treatment is tailored individually. The doctor evaluates the examination results, the stage of the disease, and the eye tissue's response to treatment.
