What Alteplase (rtPA) is used for
Alteplase (rtPA) is a specialised medicine used in ophthalmology to treat certain eye conditions. It is primarily used to:
- Dissolve fibrin clots that may form inside the eye.
- Displace submacular haemorrhage, which is bleeding that occurs under the macula, the central part of your retina responsible for sharp, detailed vision.
These conditions can significantly affect your vision, and Alteplase helps to clear these issues to improve or preserve your eyesight.
Fibrin clots can sometimes develop in the eye after surgery, trauma, or due to certain inflammatory conditions. These clots can block vision or interfere with the normal functioning of the eye. Alteplase helps to break down these clots, allowing for clearer vision and better recovery.
Submacular haemorrhage is a serious condition where blood collects under the macula. This can happen due to various reasons, including age-related macular degeneration (AMD) or other vascular conditions. The presence of blood in this critical area can severely impair central vision. Alteplase, often used in conjunction with other treatments like gas injection, helps to move this blood away from the macula, reducing its damaging effects and potentially improving visual outcomes.
It is important to understand that Alteplase is not a general-purpose eye medicine. Its use is very specific and is decided by an ophthalmologist based on a thorough examination of your eye condition.
How it works
Alteplase (rtPA) is a clot-dissolving enzyme. When injected inside the eye, it works by breaking down fibrin, which is a protein that forms the meshwork of blood clots. By dissolving these fibrin clots, Alteplase helps to clear blockages and reduce the presence of unwanted blood or fibrous material within the eye.
In simpler terms, imagine a tiny blockage or a collection of unwanted material inside your eye that is affecting your vision. Alteplase acts like a special cleaner that targets and breaks down this material, helping your eye to clear it away. For conditions like submacular haemorrhage, it helps to liquefy the blood clot and facilitate its displacement from the critical macular area.
This mechanism is very precise and is designed to work within the delicate environment of the eye, under the careful supervision of an eye specialist. The goal is to restore the clarity and function of the eye by removing these obstructing elements.
How it’s used
Alteplase (rtPA) is administered as a single injection directly into the eye. This procedure is performed by a qualified ophthalmologist in a hospital or clinic setting. It is never for self-use.
The medicine is given either as an intravitreal injection (into the vitreous gel, the clear jelly-like substance that fills the centre of your eye) or an intracameral injection (into the anterior chamber, the space at the front of your eye between the cornea and the iris).
The exact strength of the medicine used will vary, measured in micrograms, and will be determined by your ophthalmologist based on your specific condition and needs. You will receive detailed instructions from your doctor regarding preparation for the injection and what to expect during and after the procedure.
After the injection, your doctor will monitor your eye closely. You might be advised on specific post-procedure care, which could include positioning your head in a certain way, especially if gas is also injected alongside Alteplase for conditions like submacular haemorrhage. It is crucial to follow all post-injection instructions carefully to ensure the best possible outcome.
Remember, this is a highly specialised procedure, and all aspects of its administration and follow-up care will be managed by your eye specialist.
Always follow your ophthalmologist’s exact instructions.

Understanding Eye Conditions Treated by Alteplase
Alteplase (rtPA) is a medicine used to treat specific, often serious, eye conditions. One of its primary uses is to dissolve fibrin clots inside the eye. Fibrin is a protein that plays a crucial role in blood clotting. While essential for healing wounds elsewhere in the body, fibrin clots within the eye can obstruct vision, interfere with fluid drainage, or complicate recovery after eye surgery or injury. For instance, after cataract surgery, sometimes a small amount of fibrin can form in the front part of the eye, which can be problematic. Alteplase helps to break down these unwanted clots, allowing for clearer vision and promoting the eye’s natural healing processes.
Another significant use of Alteplase is to displace submacular haemorrhage. The macula is a small, highly sensitive area in the centre of your retina, responsible for your sharp, detailed central vision, which you use for reading, recognising faces, and seeing fine details. A submacular haemorrhage occurs when blood collects directly under this vital area. This can happen due to conditions like ‘wet’ age-related macular degeneration (AMD), where abnormal blood vessels leak blood, or from other vascular issues. The presence of blood under the macula can severely damage the delicate photoreceptor cells, leading to rapid and significant loss of central vision. By injecting Alteplase, the aim is to help liquefy and move this blood away from the macula, thereby reducing its toxic effects and potentially preserving or improving your central vision. This procedure is often combined with an injection of gas into the eye, which helps to push the blood away from the macula. Your doctor will explain if this combination therapy is right for you.
General Eye Care and Hygiene
While Alteplase is administered by a specialist, maintaining good general eye hygiene is always important for overall eye health, especially when recovering from any eye procedure. Always wash your hands thoroughly with soap and water before touching your eyes or any eye area. Avoid rubbing your eyes, especially after an injection, as this can introduce germs or irritate the treated area. If you are prescribed any other eye drops or ointments to use at home after your Alteplase injection, ensure you follow your doctor’s instructions precisely. When applying eye drops, tilt your head back, gently pull down your lower eyelid to form a small pocket, and drop the medicine into this pocket without touching your eye with the dropper tip. Close your eye gently for a minute or two to allow the medicine to absorb. For ointments, apply a small strip inside the lower eyelid. Always store your eye medicines as advised by your pharmacist or doctor, typically in a cool, dry place away from direct sunlight. Never share your eye medicines with anyone else, and discard any expired or unused medicines safely.
When to Seek Medical Help
After receiving an Alteplase injection, it is crucial to be aware of any changes in your eye and to know when to seek immediate medical attention. Your ophthalmologist will provide specific instructions on what to expect and what symptoms warrant concern. Generally, you should contact your doctor or go to the nearest eye emergency department if you experience any of the following: sudden or severe eye pain, significant worsening of vision, new floaters or flashes of light, increased redness or discharge from the eye, swelling around the eye, or any signs of infection. While some mild discomfort or temporary changes in vision might be normal after an eye injection, any severe or persistent symptoms should be reported immediately. It is vital to attend all follow-up appointments scheduled by your ophthalmologist, as these are essential for monitoring your recovery and the effectiveness of the treatment. Remember, your doctor is your best resource for any concerns regarding your eye health and treatment.
