Intravitreal Injections

What Are Intravitreal Injections?

Intravitreal injections are a type of medical procedure used to treat eye diseases. They involve injecting a substance into the vitreous (the clear gel that fills the eye) to help improve the patient’s vision. Intravitreal injections can be used to treat conditions such as macular degeneration, glaucoma, and diabetic retinopathy.


Which eye diseases can be treated with intravitreal injections?

Intravitreal injection treatment is an option for a number of retinal degeneration conditions, macular degeneration-related macular edema diabetic retinopathy, and age-related glaucoma.

Can intravitreal injection be used to treat macular degeneration-related macular edema in an older age group?

There is limited evidence that intravitreal injection can be used to treat macular degeneration-related macular edema in an older age group. However, there is tentative evidence that intravitreal injection may be effective in reducing the size of macular edema and improving vision. More research is needed to confirm these preliminary findings.

Can intravitreal injection be used to treat diabetic retinopathy?

The intravitreal injection can be a treatment option for diabetic retinopathy. It is an anti-vascular endothelial growth factor (VEGF) drug, which was approved by the FDA in 2013 as an anti-fibrotic medication with macular edema-associated glaucoma indication. In some studies of intravitreal injection for diabetic retinopathy, the intravitreal injection has demonstrated anti-fibrotic effects and is an effective treatment option in a subgroup of diabetic retinopathy patients.


How do they work?

Intravitreal injections are a type of eye treatment that uses a small needle to inject medication or other substances directly into the vitreous humor, the clear gel that fills the eye. Intravitreal injections can be used to treat various diseases and conditions, including myopia (nearsightedness), macular degeneration, and diabetic retinopathy. Intravitreal injections work by stimulating the growth of new blood vessels in the eye, which can improve vision.


Who is eligible for intravitreal injections?

Intravitreal injection is an intravitreal injection drug used to treat macular degeneration-related macular edema-lazy retinopathy, age-related macular degeneration, diabetic retinopathy, and ocular inflammation.

The intravitreal injection of anti-vascular endothelial growth factor (VEGF) drugs is indicated for the treatment of diabetic retinopathy patients who have subfoveal proliferative retinopathy, retinal VEGF-related macular edema, and age-related macular degeneration.

People with retinal vein occlusion (RVO) may be more likely to experience improvements in vision after intravitreal injection. Patients who are diabetic and have macular edema-related macular degeneration should receive anti-vascular endothelial growth factor injections if they do not respond enough to laser surgery, as the intravitreal injection is an effective treatment option for diabetic retinopathy patients.

Some intravitreal injection drugs include bevacizumab-Avastin®, ranibizumab-Lucentis®, and ranibizumab-Avastin®; anti-vascular endothelial growth factor (VEGF) injection drug products such as Lucentis®, Eylea™, AvastinTM, anti-vascular endothelial growth factor injection drug products such as AvastinTM, Eylea™, macular degeneration drugs including bevacizumab-Avastin®, ranibizumab-Lucentis®, ranibizumab-Avastin®, and aflibercept injection drug product.


Benefits of intravitreal injections

Intravitreal injections have been shown to be an effective way to treat a variety of eye diseases and conditions. Intravitreal injections are administered directly into the vitreous, or clear gel that fills the inside of your eye. This process allows doctors to deliver medications and other treatments directly to the damaged areas of your eye.


How do you get an intravitreal injection?

Intravitreal injections are given directly into the vitreous gel of your eye. The injection is placed deep within the retina and delivered to retinal detachments, diabetic retinopathy, macular degeneration-related vision loss, or other diseases affecting vision in your eyes.
Intravitreal injection sites include:

  • intravitreal injection of anti-vascular endothelial growth factor (anti-VEGF) drug product like AvastinTM, Eylea™, or Visudyne TM
  • intravitreal injection of macular degeneration drugs such as bevacizumab-Avastin®, ranibizumab-Lucentis®, ranibizumab injection drug products, and other retinal detachment drugs
  • intravitreal injection drug products like AvastinTM, Eylea™, or Visudyne TM of anti-vascular endothelial growth factor (anti-VEGF) drugs for retinal detachment surgery. Intravitreal injections are also used in diabetic macular edema treatment with bevacizumab injection drug products and ranibizumab injection drug products.


After your injection, what should you do to keep your eye health healthy?
After your injection, you should follow the instructions that your doctor gave you. These instructions will include things like how often to check your vision and when to call them if you have any problems. It is important to keep your eye health healthy by following these instructions so that you don’t experience any problems down the line.

Intravitreal injections are a safe and effective way to improve eye health. If you are eligible for intravitreal injections, it is important to talk to your doctor about what type of injection would be best for you.


What are the risks of getting an intravitreal injection?

Intravitreal injections (IVI) are a type of eye surgery that can be used to treat various eye diseases. The procedure is done by injecting a solution into the eye, which is then allowed to seep through the tissue and into the vitreous. This solution contains medication or a therapeutic agent.

The risks of getting an IVI include infection, which can be serious and even life-threatening, and side effects, which can include pain, blurred vision, and even loss of vision. It is important to speak with your surgeon about the risks and benefits of IVI in order to make an informed decision. Additionally, always follow your doctor’s instructions carefully and keep a journal of your medical progress for future reference.


Are there any side effects associated with this kind of treatment?

There are potential side effects associated with this kind of treatment, but most are mild and will go away after the treatment is completed. Some of the more common side effects include pain, redness, swelling, and fatigue. These side effects are usually mild and last for a few days, but should subside after the treatment is completed. If you experience any serious side effects, please contact your doctor immediately.


What is a vitrectomy and what does it involve?

A vitrectomy is a surgical procedure that involves removing a vitreous silver – or vitreous humour – from the eye. This is done to remove a blood clot, which is preventing light from reaching the retina. The vitreous humour can then be replaced with a saline solution, which helps to restore vision.


How many Intravitreal injections are needed?

This can be a difficult question to answer, as the number of Intravitreal injections required depends on a variety of factors, including the severity of the eye disease, the patient’s age, and the type of treatment being administered. However, on average, Intravitreal injections are administered every two weeks.


What are the side effects and health risks of intravitreous injections?

There are a few potential side effects and health risks of intravitreous injections, but the most common ones are injection-related pain and inflammation. In rare cases, intravitreous injections can lead to retinal detachment or other vision problems.

  • Intravitreal injections are administered with a needle the size of the facial nerve in the eye
  • The complication rate is lower in intravitreal injections than in subretinal injections
  • Intravitreal injections involve the injection of drugs in the area of the vitreous.
  • Some studies have shown that intravitreal injections have the potential to have complications not mirrored in antiretinal surgery such as cataract surgery, retinal detachment and macular edema.
  • The complication rate of intravitreal injections is generally low; however it can be higher than the complication rates of sub-retinal injection surgery when performed by an ophthalmologist with a high level of experience in intravitreal injection procedures.
  • A common and serious complication of intravitreal injections is endophthalmitis. Early diagnosis and treatment can be one of the most important steps when trying to treat this form of eye infection.
  • Prior to inserting any medication or other treatment into the patient’s eye or surrounding space, the eye care practitioner must first sterilize their hands.
  • It is important to avoid any contact at all between the medicine and the palms of your hand. It is best to have a dropper, containing the medication to be injected, that can be grasped.
  • The injections are put into the eye to wash out any infection with the antibiotic.
  • Intravitreal injections are injections used to treat bacterial endophthalmitis caused by an injury to the eye.
  • It is still not known how much the risk for endophthalmitis increases following bilateral injections.
  • Medical professionals caution against close-set or simultaneous injections because there is a higher risk of endophthalmitis.
  • Doctors will use topical anesthetics to numb the eye and hold the lid open for the intracameral injections.
  • Intravitreal injections can be used to treat eye conditions such as macular degeneration, branch retinal artery occlusions, diabetic retinopathy, and age-related macular degeneration.
  • Make sure to always inform the doctor of things such as past eye injuries, diabetes, recent surgeries, and ocular infections.
  • Intravitreal injections are a therapy that may be your last resort. Once administered, this drug immobilizes vascular endothelial cells, slowing the progression of aging-related macular degeneration and allowing your vision to improve.
  • It is best if you can get the injections done by a specialist with advanced training in the best practices involving the injections.
  • It is typically performed by an ophthalmologist or the other trained medical physician on patients with a variety of conditions such as uncontrolled glaucoma or those that are at risk of retinal detachment.
  • To facilitate the intravitreal injection, the patient is positioned to lie down and positioned so that when the patient stands up, they can stand parallel to the doctor.
  • Intravitreal injections are the preferred route for delivering anti-vegf drugs.
  • Intravitreal injections can promote photoreceptor recovery
  • Intravitreal injection is also done for patients for whom oral medication is not suitable, for example in older patients.
  • Intravitreal injections were once thought to be the cause of some of the more sinister complications that occasionally occur in patients undergoing strabismus and other cross-eyed surgeries.
  • Before performing an intravitreal injection, the attending physician disinfects their hands with alcohol and gloves.
  • Subconjunctival hemorrhage is the most common vitreous detachment complication and is caused by vitreous liquefaction within the eye.
  • Late side effects from intravitreal injections include iritis, uveitis, retinitis, glaucoma, and blindness
  • Intravitreal injections should always be administered by the most experienced physician to avoid damage to the vessels in the cornea
