How Apixaban affects the eyes

Apixaban is a medicine that is NOT used to treat eye conditions directly. Instead, it is prescribed for other health issues in the body. However, it is important for eye patients to be aware of Apixaban because it carries a risk of causing bleeding in the eyes, specifically:

• Retinal haemorrhage: Bleeding in the retina, the light-sensitive tissue at the back of your eye that is crucial for vision.
• Subconjunctival haemorrhage: Bleeding under the conjunctiva, the clear membrane that covers the white part of your eye. This often looks like a bright red spot on the white of the eye.

While Apixaban is vital for the conditions it treats, it’s crucial to understand its potential impact on your eye health. If you are taking Apixaban, your eye doctor will be mindful of these risks during your eye examinations.

How it works

Apixaban works as an anticoagulant, which means it helps to prevent blood clots from forming in your body. It does this by interfering with certain substances in your blood that are involved in the clotting process. By reducing the blood’s ability to clot, Apixaban helps to prevent serious conditions like strokes or deep vein thrombosis (DVT).

However, this very mechanism – reducing blood clotting – is why it can affect your eyes. When your blood is less likely to clot, there is an increased risk of bleeding, even from small blood vessels. This increased bleeding risk can manifest in the eyes as retinal or subconjunctival haemorrhages. It’s a systemic effect, meaning it affects the whole body, including the delicate blood vessels in and around your eyes.

Precautions & side effects

When taking Apixaban, it is generally well tolerated by most people. However, because it affects blood clotting, the most significant precaution related to your eyes is the risk of bleeding. Here are some key points to remember:

• Sudden Vision Change: If you experience any sudden changes in your vision, such as blurry vision, dark spots, floaters, flashes of light, or any loss of vision, report it to your eye doctor and your prescribing doctor immediately. These could be signs of bleeding in the retina or other parts of the eye.
• Red Spot on the Eye: If you notice a bright red spot on the white of your eye (subconjunctival haemorrhage), while often harmless, it’s important to mention it to your eye doctor, especially since you are on Apixaban.
• Regular Eye Check-ups: If you are taking Apixaban long-term, it is advisable to ask your prescribing doctor if you need regular eye check-ups to monitor for any potential ocular side effects. Your eye doctor can then perform specific examinations to check for any signs of bleeding.
• Inform All Doctors: Always inform all your doctors, including your eye doctor, that you are taking Apixaban. This is crucial because it can affect decisions regarding other medications or procedures.
• Never Self-Adjust: As reiterated, never start, stop, or change your Apixaban dosage without explicit instructions from the doctor who prescribed it to you.

While Apixaban is a critical medication for many, being aware of its potential ocular effects and reporting any concerns promptly will help ensure your overall health and vision are protected.

Understanding Your Eye Health While on Systemic Medications

At Pristine Eye Hospitals, we believe in empowering our patients with knowledge. While many medications are designed to treat specific conditions, some, like Apixaban, are taken for health issues elsewhere in the body but can have important implications for your eye health. It’s crucial to understand that Apixaban is not an eye treatment; it’s a systemic medication that affects your entire body, including the delicate structures of your eyes. Its primary role is to prevent blood clots, which is vital for many patients. However, this very action means it can increase the risk of bleeding, including in your eyes. This is why open communication between you, your prescribing doctor, and your eye specialist is so important.

When you are on a medication like Apixaban, it’s not just about taking the pill; it’s about being vigilant about your body’s signals. Any sudden changes in your vision, such as new floaters, flashes of light, blurred vision, or a sudden loss of sight, should be reported immediately. These could be signs of a retinal haemorrhage, a serious condition where bleeding occurs in the retina, the light-sensitive tissue at the back of your eye that is essential for clear vision. Even a bright red spot on the white of your eye, known as a subconjunctival haemorrhage, while often benign, warrants a mention to your eye doctor when you are on an anticoagulant. Knowing these warning signs can help in early detection and management, protecting your precious eyesight.

General Eye Care and Hygiene

Maintaining good general eye care and hygiene is always important, but it becomes even more critical when you are on systemic medications that can affect your eyes. While Apixaban is a tablet and not an eye drop, good eye hygiene helps prevent other issues that might complicate an already delicate situation. Always wash your hands thoroughly before touching your eyes, especially if you experience any irritation or need to rub them. Avoid rubbing your eyes vigorously, as this can sometimes exacerbate minor issues or, in rare cases, contribute to bleeding if blood vessels are fragile. If you wear contact lenses, ensure you follow all cleaning and storage instructions meticulously to prevent infections. Any eye infection, while generally not related to Apixaban, could potentially become more complicated if you are also dealing with other ocular issues.

For general eye comfort, ensure you get adequate rest, especially if you spend a lot of time looking at screens. Take regular breaks and practice the 20-20-20 rule: every 20 minutes, look at something 20 feet away for 20 seconds. This helps reduce eye strain. Keep your eyes hydrated; if you experience dryness, discuss it with your eye doctor, who might recommend lubricating eye drops. Remember, these are general tips for maintaining healthy eyes and are not specific to the effects of Apixaban, but they contribute to overall ocular well-being.

When to Seek Professional Help

Knowing when to seek help is paramount, especially when taking a medication like Apixaban. Your prescribing doctor manages your Apixaban dosage and overall condition, while your eye doctor monitors your ocular health. It’s a team effort. You should contact your eye doctor or seek emergency medical attention if you experience any of the following:

• Sudden, significant changes in vision: This includes sudden blurring, loss of vision in part or all of your eye, or seeing a ‘curtain’ come over your vision.
• New or increased floaters or flashes of light: While some floaters are normal, a sudden increase or new flashes could indicate a problem with the retina.
• Eye pain or discomfort: Especially if it is severe or accompanied by vision changes.
• Persistent redness or irritation: If your eyes remain red, watery, or irritated for an extended period, or if you notice any discharge.
• Any new red spots on the white of your eye: While often harmless, it’s best to get it checked, especially when on an anticoagulant.
• Any concerns about your medication: If you have questions about Apixaban’s effects on your eyes, or if you are unsure whether a symptom is serious, always err on the side of caution and contact your healthcare providers.

At Pristine Eye Hospitals, we are committed to working with your other healthcare providers to ensure your vision and overall health are protected. Always keep your eye doctor informed about all medications you are taking, and never hesitate to ask questions or report concerns.
