Optical Coherence Tomography (OCT)

Advanced technology for detecting and tracking eye disease.

We care about the health of your eyes, which is why we provide the Mount Vernon community with access to an advanced diagnostic tool that was once only available to specialized surgeons and research facilities.

Optical Coherence Tomography (OCT) is the most accurate way to detect and track eye disease, giving you the best chance to preserve the health of your eyes. We are pleased to offer this technology in the convenience of our office, saving you from additional visits to other specialists as required in the past.

Schedule an appointment with Dr. Casey Andrus today, and learn more about OCT below.

What Is an OCT Scanner?

Optical coherence tomography—or OCT—allows your eye doctor to scan and analyze the health of your eyes.

OCT uses a special technology that maps the areas of the eye that are important for sight and susceptible to eye disease.

Just like ultrasound technology, OCT provides doctors with very detailed, real-time images of eye tissue. The procedure is painless, completely non-invasive, and takes just a few minutes.

What Does OCT Diagnose?

Image generated from an OCT scanner.

An OCT scanner gives optometrists very detailed images of the back of the eye and the retina. These areas are crucial for sight and can be damaged by disease.

An OCT scan can show early signs of macular degeneration, diabetic retinopathy, glaucoma, detached retinas or other eye disorders, even before changes are seen with a dilated eye exam. The scan can also monitor changes to these tissues, down to 5 microns of detail, helping optometrists treat and manage diseases better.

How Does the Technology Work?

You can have an OCT scan right here at our office in Mount Vernon. The procedure is safe and painless, and the scanner fits on a tabletop.

During the scan, you will rest your chin comfortably while looking at a focal point inside the scanner.

We will run the scan and record detailed images of the tissue at the back of your eye. These pictures help identify areas of concern or indications of disease. This process takes place in only minutes.

Are you at risk of macular degeneration, diabetic retinopathy, glaucoma or other eye diseases? Talk to Dr. Casey Andrus at Valley Vision & Optical about ways to detect and treat these diseases before they steal your vision.
