Have you ever wondered whether or not you can have an MRI with eye stents? If so, you’re not alone. Many people have questions about the safety of MRIs when they have medical implants, and eye stents are no exception. Thankfully, the answer is not a simple yes or no. Like most medical procedures, the answer depends on your unique situation.
While eye stents are a relatively new medical treatment, they are increasingly popular amongst patients with glaucoma, a common eye condition that can lead to blindness if left untreated. Eye stents are small, flexible tubes made of biocompatible materials that are placed in the eye to help relieve pressure caused by glaucoma. Although they are minimally invasive and can help prevent vision loss, the question of whether or not they are safe during an MRI is a legitimate concern.
In this article, we’ll explore the topic of MRI safety when it comes to eye stents. We’ll look at what eye stents are, how they are placed in the eye, and what concerns there might be when undergoing an MRI with them. Whether you’re considering getting an eye stent or if you’ve already had one implanted and need to know if it’s safe to have an MRI, we’ve got you covered. Let’s dive in and explore this intriguing topic.
Understanding Eye Stents
An eye stent, also known as a glaucoma stent or trabecular micro-bypass stent, is a small device surgically implanted in the eye to reduce intraocular pressure (IOP) caused by glaucoma. Glaucoma is a group of eye diseases that result in optic nerve damage, often caused by high IOP, and can lead to blindness if untreated. Eye stents can help improve the outflow of fluid in the eye, reducing IOP and potentially slowing the progression of glaucoma.
- Eye stents are typically made of non-reactive materials, such as titanium, and are very small, about the size of a grain of rice.
- There are two main types of eye stents: trabecular stents, which are placed in the trabecular meshwork, a drainage area in the eye, and suprachoroidal stents, which are placed in the outer layer of the eye.
- Eye stents are usually implanted during a minimally invasive surgery called trabeculectomy, which involves creating a new drainage pathway for the fluid in the eye. The stent is placed in this new pathway to aid in drainage.
Eye stents can offer several benefits over traditional glaucoma treatments, such as eye drops or invasive surgeries. They are less invasive and can be performed as an outpatient procedure, which means less recovery time and fewer complications. Eye stents can also reduce the need for daily eye drops, which can be costly and difficult to remember to use. Additionally, eye stents may allow patients who were previously not candidates for surgery, due to other health conditions or the stage of their glaucoma, to undergo treatment.
Risks of Having an MRI with Eye Stents
Eye stents, which are small tubes inserted into the eye to manage intraocular pressure, are becoming more common in ophthalmology. However, patients with eye stents should exercise caution when undergoing an MRI scan, as there are potential risks involved. Here are some important things to know about the risks of having an MRI with eye stents:
- The strong magnetic fields generated during an MRI can cause the stent to dislodge or move within the eye, leading to potential complications and vision loss.
- In rare cases, the magnetic fields can heat up the eye stent and cause damage to surrounding tissues, leading to pain and discomfort for the patient.
- The presence of an eye stent can also cause artifacts on the MRI images, making it difficult for physicians to accurately interpret the images and diagnose any underlying conditions.
Due to these potential risks and complications, patients with eye stents should inform their physician and radiology technician prior to undergoing an MRI scan. It is important for the medical team to take appropriate precautions before and during the procedure to minimize the risks, such as using alternative imaging techniques or utilizing MRI compatible eye stents.
It is also important to note that patients with certain medical conditions or implants may not be eligible to undergo an MRI, as the risks may outweigh the benefits. Patients with pacemakers, cochlear implants, or other electronic devices implanted in the body are typically advised against undergoing an MRI.
| Potential Risks of MRI with Eye Stents | Precautions to Take |
|---|---|
| Dislodgement or movement of the stent within the eye | Inform physician and radiology technician prior to MRI, use alternative imaging methods |
| Heating up of the stent during MRI, causing damage to surrounding tissues | Inform physician and radiology technician prior to MRI, use MRI compatible eye stents |

Ultimately, the decision to undergo an MRI scan with an eye stent will depend on a variety of factors, such as the patient’s medical history, the condition being evaluated, and the potential risks and benefits of the procedure. Patients should consult with their physician and radiology technician to determine the best course of action.
MRI imaging options for patients with eye stents
Eye stents are typically small, implantable devices that are placed inside the eye to treat glaucoma. They work by helping to reduce intraocular pressure, which is the underlying cause of glaucoma. With the increasing number of people undergoing eye stent procedures, it’s important to know if MRI imaging is possible for patients with these devices. Here are some things you should know:
- There are different types of eye stents available, and some are more MRI compatible than others. It’s best to consult with your ophthalmologist to determine the type of eye stent you have and whether it’s safe to undergo MRI imaging.
- In general, most eye stents are made of non-magnetic materials, such as titanium or cobalt chrome. This means that they are usually safe to undergo MRI imaging as long as certain precautions are taken.
- The MRI machine generates a strong magnetic field, which can cause the eye stent to move or heat up, leading to potential complications. To avoid this, the MRI technician may need to adjust the parameters of the MRI machine, or use alternative imaging techniques such as CT scanning or ultrasound.
Precautions to take before undergoing MRI imaging with eye stents
It’s important to take certain precautions to ensure that MRI imaging is safe for patients with eye stents. Here are some guidelines:
- Make sure to inform your doctor and MRI technician that you have an eye stent.
- If you have a Medtronic XEN Gel Stent, it’s important to follow the manufacturer’s guidelines, which state that the stent should not be exposed to an MRI field strength exceeding 1.5 Tesla. Your doctor may advise you to have your stent removed before undergoing MRI imaging.
- If you have a Glaukos iStent or iStent Inject device, these are generally considered safe for MRI imaging. However, the MRI technician may need to adjust the MRI parameters to ensure safety.
Conclusion
Patients with eye stents may be able to undergo MRI imaging, depending on the type of stent they have and certain precautions that must be taken.

- Optical Coherence Tomography (OCT): OCT produces detailed images of the retina and optic nerve using light waves. It’s a quick, non-invasive, and painless process that helps doctors detect eye conditions like glaucoma, macular degeneration, and diabetic retinopathy.
- Fluorescein Angiography: This test uses a dye that’s injected into a vein in the patient’s arm. The dye travels to the blood vessels in the eye, where a camera takes pictures of the blood flow in the retina and choroid. This method is useful for diagnosing eye conditions like macular degeneration and diabetic retinopathy.
While none of these alternative techniques can fully replace MRI, they can provide valuable diagnostic insights for patients with eye stents.
It’s important for patients to discuss their medical history and any pre-existing conditions with their doctors before undergoing any imaging tests. This will help them determine the best course of action and decide which imaging technique is right for them.
| Imaging Technique | Benefits | Limitations |
|---|---|---|
| Ultrasound | Non-invasive, painless, quick, can detect early eye diseases | Not as detailed as MRI, may not detect all eye conditions |
| Optical Coherence Tomography | Non-invasive, painless, quick, can detect various eye diseases | Not as detailed in showing blood flow in the eye as other techniques |
| Fluorescein Angiography | Can detect blood flow issues in the retina and choroid, useful for diagnosing macular degeneration and diabetic retinopathy | Dependent on the injected dye, can have side effects, invasive |
Ultimately, patients with eye stents have several alternative imaging options to choose from. Discussing their medical history and opting for the most suitable imaging technique will help doctors provide the most accurate diagnosis and treatment.
