What Dexamethasone Intravitreal Implant is used for
Dexamethasone Intravitreal Implant is a special medicine used to treat specific eye conditions that cause swelling inside your eye. These conditions can affect your vision and overall eye health. Your eye doctor might recommend this treatment if you have:
- Diabetic macular oedema: This is a common complication of diabetes where swelling occurs in the macula, the central part of your retina responsible for sharp, detailed vision. This swelling can blur your vision.
- Macular oedema after retinal vein occlusion: Retinal vein occlusion happens when a blood vessel in your retina gets blocked, leading to fluid leakage and swelling in the macula, which can affect your vision.
- Non-infectious posterior uveitis: Uveitis is inflammation inside your eye. Posterior uveitis specifically affects the back part of your eye and can cause pain, redness, and vision problems. This implant is used for cases that are not caused by an infection.
By reducing inflammation and swelling, this implant aims to improve your vision and protect your eye health.
How it works
Dexamethasone Intravitreal Implant works by delivering a powerful anti-inflammatory medicine called dexamethasone directly into your eye. It is a tiny, biodegradable rod, meaning it is designed to slowly dissolve over time. Once injected into the vitreous (the jelly-like substance that fills the centre of your eye), this implant gradually releases the steroid medicine over several months. This slow and steady release helps to reduce inflammation and swelling in the affected parts of your eye, such as the macula or the posterior uvea. Because the medicine is released directly inside the eye, it can target the problem area effectively and continuously, helping to control the condition and improve your vision.
How it’s used
Dexamethasone Intravitreal Implant is administered by a specialist eye doctor in a hospital or clinic setting. It is not a medicine you can use yourself. The doctor will carefully inject one implant into your eye. The effect of this single implant typically lasts for about 3 to 6 months. Your eye doctor will monitor your condition regularly and decide if and when another implant is needed based on your response to the treatment and the ongoing health of your eye. It is very important to attend all your follow-up appointments so your doctor can check your eye pressure and overall eye health.
Always follow your ophthalmologist’s exact instructions.

Important safety warning
STEROID — DO NOT SELF-MEDICATE. Unsupervised or prolonged use of steroid eye medication can cause steroid-induced glaucoma (silent, irreversible optic-nerve damage) and cataract, and can turn a viral or fungal eye infection into a sight-threatening one. Use only on an eye doctor's prescription, for the stated duration, with eye-pressure checks. Never repeat an old prescription for a red eye. This is given only by specialists in a hospital or clinic setting and is never for self-use.
Precautions & side effects
While Dexamethasone Intravitreal Implant can be very effective, there are important precautions and potential risks to be aware of:
- Raised Eye Pressure: One of the main risks associated with steroid treatments in the eye is an increase in eye pressure. If left untreated, high eye pressure can lead to a condition called glaucoma, which can cause silent, irreversible damage to the optic nerve and vision loss. Your doctor will monitor your eye pressure regularly after the implant.
- Cataract Formation: Steroid use in the eye can also increase the risk of developing cataracts, which is a clouding of the natural lens of your eye that can blur your vision.
- Not Always First Choice for Young Eyes: This implant is generally not the first choice of treatment for younger patients who still have their natural lens (known as a ‘phakic eye’), due to the increased risk of cataract formation.
- Alternative for Frequent Injections: This treatment can be particularly useful for patients who find it difficult to come for monthly eye injections, as its effect lasts for several months.
- Critical Warning – STEROID – DO NOT SELF-MEDICATE: This is a critical warning for all steroid medications. Dexamethasone Intravitreal Implant is a powerful steroid. It must ONLY be used under the direct supervision and prescription of an eye specialist in a hospital or clinic. Unsupervised or prolonged use of any steroid eye medication can lead to severe and permanent eye damage, including steroid-induced glaucoma (irreversible optic nerve damage) and cataracts. It can also worsen viral or fungal eye infections, turning them into sight-threatening conditions. Never use this or any other steroid eye medicine without a doctor’s prescription, for longer than prescribed, or to treat a ‘red eye’ based on an old prescription. Your eye doctor will perform necessary eye pressure checks and determine the appropriate duration of treatment.
Always discuss any concerns or questions you have with your eye doctor before and during your treatment.
Understanding Your Eye Condition and Treatment
At Pristine Eye Hospitals, we believe that understanding your eye condition and the treatment you receive is a vital part of your journey to better eye health. Dexamethasone Intravitreal Implant is used to treat specific conditions that involve swelling and inflammation inside your eye. For instance, Diabetic Macular Oedema (DMO) is a common complication for people with diabetes. High blood sugar levels can damage the tiny blood vessels in your retina, causing them to leak fluid and swell the macula – the central part of your retina responsible for sharp, detailed vision. This swelling can make your vision blurry or distorted. Similarly, Macular Oedema after Retinal Vein Occlusion occurs when a blood vessel in your retina gets blocked, leading to fluid buildup and swelling in the macula, which again impacts your central vision. Non-infectious Posterior Uveitis is an inflammation of the back part of your eye that is not caused by an infection. This inflammation can cause pain, redness, light sensitivity, and reduced vision. All these conditions share a common problem: inflammation and swelling that can severely affect your vision if not managed properly. The Dexamethasone Intravitreal Implant is designed to specifically target this inflammation and swelling, helping to preserve and improve your eyesight.
It’s important to remember that these conditions often require ongoing care. Regular follow-ups with your eye doctor are crucial to monitor the effectiveness of the treatment, check for any potential side effects, and ensure your eye health remains stable. Your doctor will guide you through the treatment plan and explain what to expect at each stage. Living with an eye condition can be challenging, but with proper medical care and understanding, you can manage it effectively and maintain your quality of life.
General Eye Care and Hygiene
While the Dexamethasone Intravitreal Implant is administered by your doctor, maintaining good general eye hygiene is always important, especially when undergoing eye treatment. Always wash your hands thoroughly with soap and water before touching your eyes or any eye medication. Avoid rubbing your eyes, as this can introduce germs and potentially irritate them. If you use other eye drops or ointments, make sure to follow your doctor’s instructions precisely regarding their application and timing. Store all eye medications as advised by your doctor or pharmacist, usually in a cool, dry place away from direct sunlight. Never share your eye medications with anyone else, as each treatment is prescribed specifically for your condition. If you wear contact lenses, your doctor will advise you on when it is safe to wear them after the implant procedure. Generally, it’s best to avoid wearing contact lenses for a period after any intraocular injection to prevent infection and allow the eye to heal.
When to Seek Immediate Medical Help
After receiving a Dexamethasone Intravitreal Implant, it’s important to be aware of certain symptoms that might indicate a complication and require immediate medical attention. While your doctor will provide specific post-procedure instructions, generally, you should contact Pristine Eye Hospitals or seek emergency care if you experience any of the following:
- Sudden, severe eye pain that does not go away.
- Significant decrease in vision or sudden vision loss.
- Increased redness of the eye that worsens over time.
- New or worsening sensitivity to light.
- Seeing flashes of light or an increase in floaters (small specks or cobweb-like images that drift across your vision).
- Pus or discharge from the eye.
- Any symptoms that seem unusual or concerning to you.
These symptoms could indicate an infection, a significant rise in eye pressure, or other serious complications. Prompt medical attention can help prevent further damage and ensure the best possible outcome for your vision. Always keep the contact information for Pristine Eye Hospitals readily available.
