Title: Intravitreal Injections: Everything You Need to Know Author: Not specified Reviewer: Not specified Commissioner: Not specified Production Information/Organization: Aier Hospital Group Profile: The injection of medication into the vitreous offers hope to patients with eye diseases by effectively treating deep lesions. Keyword: ['Ophthalmology', 'Health']

Recently, a middle-aged diabetic patient experienced a decrease in vision and blurred sight, prompting him to visit an ophthalmology hospital for an examination. The doctor recommended an intravitreal injection. The patient couldn't help but worry: given his age, is it safe to administer "injections" in the eyes?

In fact, the intravitreal injection, commonly referred to as "giving an injection to the eye", is a frequently performed ocular procedure in ophthalmology clinics.

The procedural steps are as follows: first, anesthetic eye drops are applied to the eye, then the doctor uses a specialized injection needle to penetrate the ciliary body flat area, about 3-4 millimeters behind the limbus, injecting the medication into the vitreous cavity to allow the drug to take effect for treatment purposes.

Due to the fact that intravitreal injection bypasses the blood-ocular barrier, the medication acts more specifically and can quickly achieve a high local concentration, increasing its therapeutic effectiveness while reducing systemic toxic reactions. This allows for better control of disease progression and is particularly notable in the treatment of many retinal diseases.

Most patients undergoing intravitreal injections typically require monthly injections over a continuous period of 3 to 4 months. After this duration, the doctor will assess the clinical situation to determine if further medication administrations are necessary.

In simple terms, the intravitreal injection of medication is like sending a "precision package" into the eye. With a rigorous sterile technique, the doctor uses a very thin needle to inject the medication directly into the vitreous of the eye. This is akin to delivering the medication directly to the "doorstep" of the ocular disease, which can be effective for deep eye diseases that cannot be treated with eye drops.

The intravitreal injection of medications is an important treatment method for many patients with retinal diseases. It can be effective in managing various ocular diseases, particularly suitable for some of the more common retinal conditions, such as:

1. Wet age-related macular degeneration (wAMD): Elderly individuals are more susceptible to issues in the macular area, and this can offer help.

2. Diabetic macular edema (DME): It is a fluid accumulation in the macula caused by diabetes, which can provide therapeutic effects.

3. Retinal vein occlusion (RVO) secondary to macular edema: Macular edema caused by vascular obstruction, which has a corresponding treatment.

4. Pathological choroidal neovascularization related to myopia (mCNV): A neovascularization issue in the fundus caused by high myopia, which can be treated.

5. Severe ocular inflammation or infection: When the eyes show inflammation or infection, it may have anti-inflammatory and bactericidal effects.

6. Other retinal vascular or inflammatory diseases: Any issues related to blood vessels in the eye fundus or inflammation can be treated.

1. Postoperative care

Timely medication intake: Strictly follow the doctor's instructions and use the prescribed antibiotic eye drops on time to prevent infections.

Eye protection: Avoid rubbing the eyes and pressing the eyeball on the same day as surgery; treat the eye area gently.

Waterproof and dirt-resistant: During the two weeks following surgery, prevent dirty water from entering the eyes when washing the face or hair, and swimming or soaking in hot springs is prohibited to prevent any discomfort in the eyes.

Avoid makeup: Do not apply eye makeup in the weeks following surgery, and wait for the eye area to fully recover before reapplying.

Adequate rest: Avoid intense exercises and heavy physical work, ensuring sufficient rest for the eyes.

2. Postoperative review plan.

First review: It is essential to visit the hospital the day after the surgery. The doctor will assess the wound recovery, intraocular pressure, and the situation regarding potential infections.

Secondary review: Approximately one week after the surgery, a new review will be conducted to assess the progress of the recovery.

Regular review: Subsequently, periodic check-ups will be conducted as requested by the doctor to monitor the effectiveness of the treatment. The doctor will determine the next injection time based on these assessments.

3. Indications for emergency medical attention.

If severe eye pain, rapid vision loss, worsening eye redness and swelling, a large amount of purulent discharge, or a sudden increase in black shadows moving or flashes of light occur, medical attention should be sought immediately.
