What Intravenous Immunoglobulin (IVIG) is used for
Intravenous Immunoglobulin (IVIG) is a powerful medicine used to treat specific, serious eye conditions that involve an overactive immune system affecting the nerves around the eye. At Pristine Eye Hospitals, our specialists may recommend IVIG for:
- Myasthenic crisis: This is a severe worsening of myasthenia gravis, a condition where the immune system attacks the connections between nerves and muscles, leading to extreme muscle weakness, including those controlling eye movement and breathing.
- Atypical optic neuritis: This refers to inflammation of the optic nerve (the nerve that carries visual information from the eye to the brain) that doesn’t follow the typical pattern seen in other conditions. It can cause sudden vision loss.
- NMOSD relapse: NMOSD stands for Neuromyelitis Optica Spectrum Disorder. This is a rare, chronic autoimmune disease that primarily affects the optic nerves and spinal cord. A relapse means a sudden worsening of symptoms or new symptoms appearing.
By treating these conditions, IVIG aims to reduce inflammation, protect nerve function, and help improve or preserve vision.
How it works
Intravenous Immunoglobulin (IVIG) works by providing your body with a concentrated dose of pooled antibodies. These antibodies are collected from thousands of healthy donors. When infused into your bloodstream, these ‘good’ antibodies help to modulate or calm down an overactive immune system. In conditions where your own immune system mistakenly attacks healthy tissues, such as the nerves in and around your eyes, IVIG can help to rebalance this immune response. It acts like a ‘reset button’ for the immune system, reducing the harmful activity of your body’s own antibodies and inflammatory processes that cause damage in conditions like myasthenic crisis, atypical optic neuritis, and NMOSD relapse.
How it’s used
Intravenous Immunoglobulin (IVIG) is administered as an IV (intravenous) infusion, which means it is given directly into your vein through a drip. This treatment is always carried out in a hospital or clinic setting under the close supervision of specialists. It is never for self-use at home.
The dosing of IVIG is carefully calculated based on your body weight to ensure you receive the correct amount. A typical dosing regimen might involve receiving 0.4 grams per kilogram of your body weight per day, usually for a period of 5 days. However, the exact dose and duration will be determined by your ophthalmologist based on your specific condition, its severity, and your response to the treatment.
During the infusion, healthcare professionals will monitor you closely for any reactions. It’s important to communicate any discomfort or unusual feelings you experience during or after the infusion to your medical team. Your doctor will explain the full treatment plan and what to expect.
Always follow your ophthalmologist’s exact instructions.

Precautions & side effects
When receiving Intravenous Immunoglobulin (IVIG), several precautions are taken to ensure your safety and the effectiveness of the treatment:
- Hospital Infusion: IVIG is always given in a hospital or clinic setting. This is crucial because it allows medical staff to closely monitor you during the infusion and manage any potential reactions immediately.
- Hydration: It is very important to stay well-hydrated before, during, and after your IVIG infusion. Your doctor or nurse will advise you on how much fluid to drink. Good hydration helps your body process the medicine and can reduce the risk of certain side effects.
- Renal Caution: Your doctors will pay close attention to your kidney function, especially if you have existing kidney issues. IVIG can sometimes affect the kidneys, so regular monitoring of kidney health through blood tests may be necessary during your treatment.
- Allergic Reactions: Although rare, some individuals may experience allergic reactions to IVIG. The medical team will be prepared to manage these. It’s important to inform your doctor about any known allergies you have.
- Other Potential Side Effects: While generally well-tolerated, some patients might experience mild side effects such as headache, fever, chills, or nausea. These are usually temporary and manageable. Your medical team will discuss potential side effects with you and how they will be addressed.

Understanding Conditions Treated by IVIG
At Pristine Eye Hospitals, we understand that conditions affecting your vision and the nerves around your eyes can be concerning. Intravenous Immunoglobulin (IVIG) is a specialized treatment used for certain serious neuro-ophthalmological conditions where your immune system plays a key role. For example, in Myasthenic crisis, which is a severe flare-up of myasthenia gravis, the immune system mistakenly attacks the connections between nerves and muscles. This can lead to extreme muscle weakness, affecting eye movements, swallowing, and even breathing. IVIG helps to calm this overactive immune response. Similarly, in Atypical optic neuritis, the optic nerve – which is vital for carrying visual information from your eye to your brain – becomes inflamed due to an unusual immune reaction, potentially causing sudden vision loss. For patients with NMOSD relapse (Neuromyelitis Optica Spectrum Disorder), where the immune system attacks the optic nerves and spinal cord, IVIG can help reduce the severity of a relapse and protect against further damage. Our specialists at Pristine Eye Hospitals will thoroughly explain your specific condition and how IVIG fits into your treatment plan, ensuring you feel informed and supported throughout your journey to better eye health.
Receiving Your IVIG Treatment
As IVIG is given as an intravenous (IV) infusion, it means the medicine is delivered directly into your bloodstream through a drip, typically into a vein in your arm. This procedure is always performed in a hospital or clinic setting, under the careful supervision of our trained medical staff. You will be made comfortable, and the healthcare team will monitor you closely throughout the infusion. The duration of each infusion session can vary, and your doctor will inform you about the expected schedule. It’s important to remain calm and communicate any unusual feelings or discomfort you might experience during the infusion, such as headache, dizziness, or any changes in how you feel. Our team is always there to ensure your comfort and safety. After the infusion, you may be observed for a period before being discharged, and your doctor will provide specific instructions for your care at home, including any follow-up appointments or signs to watch out for. Remember, this is a hospital-administered treatment and never for self-use.
General Advice for Eye Health and When to Seek Help
Maintaining good overall health is crucial when undergoing treatment for eye conditions. This includes following a balanced diet, getting adequate rest, and managing any other health conditions you may have. For general eye care, always practice good hygiene: avoid touching or rubbing your eyes unnecessarily, and if you use any other eye drops or ointments (though IVIG is not an eye drop), ensure your hands are clean before application. Store all medicines, including any other prescribed eye drops, as directed by your pharmacist, typically in a cool, dry place away from direct sunlight and out of reach of children. It is vital to attend all your scheduled follow-up appointments at Pristine Eye Hospitals. These appointments allow your ophthalmologist to monitor your progress, assess the effectiveness of the IVIG treatment, and make any necessary adjustments to your care plan. If you experience any sudden changes in your vision, new or worsening symptoms, severe pain in or around your eyes, or any unexpected reactions after your IVIG treatment, do not hesitate to contact Pristine Eye Hospitals immediately or seek emergency medical attention. Your health and vision are our top priority, and prompt action can make a significant difference in managing your condition effectively.
