Optical Coherence Tomography
What Is Optical Coherence Tomography (OCT)?
When it comes to ensuring vision health, retina specialists require high-quality images of the retina. The advanced diagnostic tool known as Optical Coherence Tomography (OCT) is a safe, non-contact, and non-invasive imaging technique that is commonly used by retina specialists to check on various aspects of vision health.
As such, OCT is a common diagnostic test for a variety of conditions affecting the retina, the vitreous, and the macula—the retina's center that enables central, close-up vision (such as reading or seeing faces). Among these conditions are age-related macular degeneration (AMD), central serous retinopathy, epiretinal membranes, glaucoma, macular edema, macular holes, and retinal inflammatory diseases.
How Does OCT Work?
OCT is similar to the technology associated with computed tomography (CT) scans of internal organs. Essentially, OCT employs a scattering of infrared light waves to rapidly scan the eye. This allows the capture of high-resolution, cross-sectional images of the structures within your retina. These images are highly detailed, clear, and accurate. In addition, OCT can measure the thickness of retinal nerve fiber layers. As such, it provides an effective means to diagnose diseases of the optic nerve, such as glaucoma.
Another benefit of OCT is that, unlike other imaging techniques, no radiation, sound, or radiofrequency waves are involved. Therefore, you don’t have to worry about health risks or harmful side effects.
