What Should I Expect During an OCT Scan?

An OCT scan is one of the most advanced diagnostic tools used in modern eye care. This powerful imaging technology allows your eye doctor to closely examine the health of your retina and catch potential issues early.

What Is an OCT Scan?

An OCT scan uses light waves to create high-resolution images of the layers of your retina, the light-sensitive tissue at the back of the eye. Because it provides such precise detail, OCT is commonly used to evaluate and manage conditions such as macular degeneration, glaucoma, diabetic eye disease, and retinal swelling.

What Happens During the Test?

The OCT scan itself is fast and painless. You’ll be seated in front of the OCT machine and asked to rest your chin on a support while looking at a fixation target. The device does not touch your eye. As the scan is performed, you’ll see flashes of light while the machine captures images. Each eye usually takes only a few seconds to scan, and the entire process is typically completed within minutes.

Is the OCT Scan Uncomfortable?

Most patients find OCT scans very easy. There is no contact with the eye, no injections, and no radiation. The only mild discomfort some people experience comes from pupil dilation rather than the scan itself.

What Do the Results Show?

The images from your OCT scan allow your eye doctor to evaluate the thickness and structure of the retina in great detail. These results help identify early signs of disease, track changes over time, and guide treatment decisions. In many cases, your doctor can review the images with you during the same visit and explain what they show.

Why OCT Scans Are Important

OCT technology plays a critical role in modern eye care. Because many eye diseases develop gradually and without early symptoms, OCT scans help catch problems sooner - often before vision loss occurs. Early detection means earlier treatment and better long-term outcomes for your vision.

How Often Will I Need an OCT Scan?

The frequency of OCT scans is typically annual and performed as part of a comprehensive eye exam. This routine imaging allows your eye doctor to monitor the health of your retina over time and detect subtle changes early, even before symptoms develop. Your doctor may recommend additional scans if you have specific eye conditions or risk factors that require closer monitoring.

Take the Next Step in Protecting Your Vision

An OCT scan is a simple, safe, and highly effective tool that provides valuable insight into your eye health. Knowing what to expect can help you feel confident and comfortable during your visit.
