This is when you start being offended by the phrase “I’d rather poke myself in the eye with a sharp stick/pencil/needle” or whatever iteration you hear. You don’t think it’s a common phrase until you start getting poked with a sharp needle in your eye to attempt to save your vision. Then you seem to hear it all the time. And you won’t joke about it or wish it on anyone. Cross my heart and hope to die… you know the rest.
An intravitreal steroid implant injection is a treatment for posterior uveitis during which an implant with corticosteroid is injected into the vitreous (clear gel part) of the eye. It’s a shot right at the target (localized) and allows the rest of the body to be spared side effects of high doses of steroids. Often implants are done in conjunction with lower doses of systemic medication.
The intravitreal implant technology is a relatively new advancement; the first implant was approved by the Federal Drug Administration (FDA) in 2009. The capsule design facilitates the sustained release of steroids, which allows for more time in between injections, theoretically. Realistically, every patient’s eye reacts differently to the treatment. One downside to these implants is that there is no manner of knowing when the implant has actually run its course and is no longer releasing medication.
Before intravitreal implants, corticosteroids were injected into the periocular space (around the eyeball). Now, with the implant injection into the vitreous, the lack of fluid flow in the vitreous humor leads to a higher concentration of the steroid, which is effective for inflammation control (https://www.ondrugdelivery.com/sustained-drug-delivery-posterior-segments-eye/).
However, increased ocular pressure and cataracts are almost unavoidable side effects of intravitreal steroid implants. Infection and retinal detachment are risks of the injections. Read more about side effects and complications of treatments here.
I’ve had eight intravitreal injections. Five in the left eye (Ozurdex and Iluvien) and three in the right (Iluvien, Ozurdex and, most recently, Yutiq). This is my experience and these are my tips.
Intravitreal implants are administered via in-office procedures that can be planned or immediate depending on the case and the patient’s insurance.
Injectable intravitreal steroid implants for uveitis include the following:
Ozurdex contains .7 mg of dexamethasone. The implant is 6mm long and .46mm in diameter. It biodegrades into lactic and glycolic acid. It is injected with a 22 gauge syringe and is projected to disperse steroids for around six months with a peak concentration at two months. Ozurdex was approved by the FDA in 2009 for “noninfectious uveitis affecting the back segment of the eye.”
Iluvien contains .19mg of fluocinolone acetonide. It is injected with a 25 gauge syringe and is projected to disperse steroids for 36 months (three years). This injection is indicated for diabetic macular edema. Iluvein was approved by the FDA in 2014.
Yutiq contains .18mg of fluocinolone acetonide with an initial dispersal rate of .25mg. It is 3.5mm long. It is injected with a 25 gauge syringe and is projected to disperse steroids for 36 months (three years). Yutiq was approved by the FDA in 2018 for “treatment of chronic non-infectious uveitis affecting the posterior segment of the eye”.
Check out the individual product manufacturer websites for financial assistance if your insurance isn’t going to cover the procedure and device. You will need it. Bills for the injection and the visit run about $13,000 when billed through insurance in my experience. Your doctor’s office billing department should be able to assist or, hopefully, handle the whole process.
Don’t be afraid to ask for a prescription for valium or some type of relaxant to take ahead of time if you’re anxious (unless you’re pregnant or breastfeeding). I find that meditation and yoga practice in my daily life help manage my anxiety during injections.
Make sure to arrange for someone to drive you home after the injection.
The care team will begin by marking your forehead above your eye and confirming the eye and the injection. Cleaning of your eye, lid, and lashes comes next by way of drops. My doctor’s office uses numbing drops and a numbing gel, which is heavy and sticky but does the trick! If you feel any stinging with the drops, tell the assistant or doctor and get more gel!
One of the worst parts (maybe the worst in my opinion) of the entire procedure is the eye speculum. This is the metal retractor that holds your eye open. Something that has helped the comfort of the injections for me immensely is that my doctor smushed down the speculum so it didn’t open so wide. If you have a smaller face, perhaps request a pediatric speculum or ask your doctor to reshape this device to the least possible width needed for the procedure.
Blink and the doctor places the speculum. Now is the time to start your deep breathing or relaxation technique. Focus on relaxing your face; tensing up and increased blinking will make the speculum more uncomfortable.
Depending on the gauge of the implant injection needle, your doctor and your preference, your doctor will now inject medication into your eye to numb it. This hurts even with the numbing gel. Look where your doctor instructs. Breathe. Unclench your fists and go to your “happy place.”
Next comes the actual implant injection. This can feel like a lot of pressure on the eye depending on the injection. Ozurdex has a definite “click.” Yutiq seemed to require more pressure than Iluvien in my experience.
More than likely, your injection site will bleed (hemorrhage), especially if you opt for the numbing injection. One of the first injections I received bled so bad the blood spread throughout my entire eye. I stayed home from work. My husband and I had a snowboarding trip already planned that weekend with friends and I deleted the photos.
In addition, I was unprepared for all of the stares and flat out rude comments I received. It made me thankful for once to have posterior uveitis that normally is unseen (folks with Anterior or Panuveitis are probably used to this!). References people that I had never met made to physical or domestic abuse astounded me and still does when I get injections! So, decide ahead of time how you would like to react or not react to any comments that come up. I don’t even waste my breath on a response to comments or questions that are off-color or cruel.
I have found that putting an ice pack on the eye repeatedly for about 20 minutes at a time significantly decreased the bleeding and swelling for me. Make sure to rest the eye that day even if you don’t feel like it’s necessary. Take over-the-counter medication for pain or headaches.
The following survey was conducted with folks who get injections far more often than I, but I agree that injections can bring on anxiety and headaches. Survey: Intravitreal Injections Linked to Discomfort, Anxiety
Last, but not least, be diligent about any follow-up medications or drops your provider has prescribed.
Now, move about your life knowing that you are a badass who can handle getting a needle or two in the eye.
