What Aspirin is used for
Aspirin is prescribed by ophthalmologists at Pristine Eye Hospitals primarily for conditions where blood clot formation might affect the eyes. It is used to:
- Secondary prevention after ischaemic optic/retinal vascular events: This means it helps prevent future episodes of vision loss or damage to the eye’s blood vessels after an initial event caused by a lack of blood flow.
- Giant Cell Arteritis (GCA) adjunct: It is used as an additional treatment alongside other medicines for Giant Cell Arteritis, a condition that causes inflammation of blood vessels, which can affect the eyes.
How it works
Aspirin works by reducing the formation of blood clots in your body. It does this by affecting tiny cells in your blood called platelets. Platelets are essential for stopping bleeding, but sometimes they can clump together too much and form clots that block blood vessels. By inhibiting these platelets, Aspirin helps to keep blood flowing smoothly, which is crucial for preventing further damage to the delicate blood vessels in and around your eyes.
How it’s used
Aspirin is available in tablet form and is typically taken by mouth. Your ophthalmologist will advise you on the exact dosage and how often you should take it. The usual dose for eye-related conditions is 75-150 mg once a day. It is very important to follow your doctor’s instructions precisely and not to change your dose without consulting them. Remember, this medicine is for preventing future events and is not meant to treat an acute, sudden event itself.
Always follow your ophthalmologist’s exact instructions.

Precautions & side effects
While Aspirin is an important medicine, it’s essential to be aware of certain precautions:
- Gastric Caution: Aspirin can sometimes irritate the stomach. If you have a history of stomach ulcers, heartburn, or other digestive issues, please inform your doctor. They may advise you on how to take the medicine to minimise stomach discomfort, such as taking it with food.
- Not for Acute Events: It is crucial to understand that Aspirin is used for the secondary prevention of events, meaning it helps prevent future problems. It is not a treatment for a sudden, acute event like a sudden loss of vision or a new blood clot. If you experience any sudden changes in your vision or other concerning symptoms, seek immediate medical attention.

Understanding Eye Conditions Treated by Aspirin
At Pristine Eye Hospitals, we believe in empowering our patients with knowledge about their eye health. Aspirin is prescribed for specific conditions that affect the blood supply to your eyes. One key use is for ‘secondary prevention after ischaemic optic/retinal vascular events’. This refers to situations where the blood flow to the optic nerve (which connects your eye to your brain) or the retina (the light-sensitive tissue at the back of your eye) has been reduced, leading to vision problems. These events can be caused by small blood clots blocking the tiny blood vessels. Aspirin helps to prevent these clots from forming again, thereby protecting your vision from future damage. It’s like ensuring the pipes carrying water to your house remain clear to prevent future water supply issues. Another important use is as an ‘adjunct’ (meaning an additional treatment) for Giant Cell Arteritis (GCA). GCA is a serious inflammatory condition where the body’s immune system mistakenly attacks and inflames medium to large arteries, including those that supply blood to the eyes. If left untreated, GCA can lead to sudden and permanent vision loss. While other medicines are the primary treatment for GCA, Aspirin plays a supportive role by helping to reduce the risk of clot formation in these inflamed vessels, offering an additional layer of protection for your eyes. Understanding these conditions helps you appreciate why your ophthalmologist has prescribed Aspirin and how it contributes to maintaining your eye health.
General Advice for Taking Your Medicine
Taking your medicine correctly is crucial for its effectiveness and your safety. Since Aspirin for eye conditions is typically taken as a tablet, here are some general guidelines. Always take your Aspirin tablet with a full glass of water. If your doctor advises taking it with food, it’s usually to help reduce any potential stomach discomfort. Try to take your medicine at the same time each day, as this helps maintain a consistent level of the drug in your body and makes it easier to remember your dose. Do not crush, chew, or break tablets unless specifically instructed by your doctor, as some tablets are designed to release the medicine slowly. If you miss a dose, take it as soon as you remember, unless it’s almost time for your next dose. In that case, skip the missed dose and continue with your regular schedule. Do not double up on doses to make up for a missed one. If you have any doubts or concerns about how to take your Aspirin, always consult your ophthalmologist or the pharmacist at Pristine Eye Hospitals. They are there to help clarify any instructions and ensure you are taking your medicine safely and effectively.
When to Seek Medical Help
While Aspirin is generally safe when used as directed, it’s important to be vigilant and know when to seek medical attention. If you experience any unusual or severe side effects, such as persistent stomach pain, black or tarry stools (which could indicate stomach bleeding), unusual bruising or bleeding, or any allergic reactions like rash, itching, or swelling, contact your doctor immediately. Remember that Aspirin is for prevention, not for treating acute events. If you experience any sudden changes in your vision, such as sudden blurriness, loss of vision in one eye, or seeing flashing lights or floaters, do not wait. These could be signs of a serious eye condition that requires immediate medical evaluation. Similarly, if you notice any new or worsening headaches, scalp tenderness, jaw pain while chewing, or fever, especially if you are being treated for Giant Cell Arteritis, contact your ophthalmologist or seek emergency medical care right away. Always keep your follow-up appointments with your ophthalmologist at Pristine Eye Hospitals. Regular check-ups are vital to monitor your eye health and the effectiveness of your treatment. Your doctor can adjust your treatment plan if needed and address any concerns you may have. Your health and vision are our priority.
