An OCT retinal scan (Optical Coherence Tomography) is an imaging procedure that eye doctors use to examine the layers of the retina, the thin tissue at the back of the eye that detects light and sends information to the brain.
You can think of it as an “X-ray” for your retina, but instead of harmful rays, light waves are used to create detailed 3D images of the inside of your eye. This test is quick, painless, and helps the doctor determine if there are any problems, such as:
- Glaucoma,
- Macular degeneration (age-related vision loss),
- Diabetic eye disease, or
- Retinal tears or swelling.
Using a scan, your eye doctor is able to see your eye’s health in great detail, catching problems even before they become symptoms.
Why is an OCT Scan important?
Our most common question is “do I have to get it done?” and simply answered—we strongly recommend it. Having this procedure incorporated into your eye exam has many benefits, including:
- Early Detection of Eye Diseases: OCT scans can identify eye diseases such as glaucoma, age-related macular degeneration, and diabetic retinopathy before symptoms appear. Early detection allows for timely treatment, which is vital for preventing vision loss.
- Monitoring Disease Progression: In patients with retinal conditions, OCT scans are useful for monitoring treatment effectiveness and monitoring disease progression.
- Non-Invasive and Painless: The procedure is quick, painless, and does not require direct contact with the eye, so patients should find it comfortable.
How does an OCT Scan work?
In OCT scans, light waves are directed towards the eye and measured for how fast they reflect back from the retina’s layers. With this process, detailed, three-dimensional images of the retina are created, making it possible to assess the health of the retina in great detail.
Are there any side effects associated with an OCT Scan?
The OCT scan carries no risks or harmful impacts. However, having your pupils dilated can have short-term effects like blurry vision or light sensitivity. Due to this, it will take some time for your eyes to adjust so, we suggest you make arrangements for someone else to drive you home from the test.
Next Steps:
Wondering, “What happens next?” Don’t worry—we’ve got you covered! Your eye doctor will review the images from your OCT scan. If you’ve had previous scans, they’ll compare them to look for any changes. They’ll share their findings with you as soon as possible, helping to confirm if there’s a condition affecting your retina or optic nerve and how advanced it might be. With this information, your eye doctor will guide you on the next steps for your treatment plan.
Overall, including an OCT (Optical Coherence Tomography) scan in your eye check ups is an important step toward maintaining your eye health. This imaging technology allows your optometrist to take a close look at your retina and optic nerve, making it simpler to diagnose any eye or health issues. Early detection allows for timely treatment, which can help protect your vision!
