optical coherence tomography (OCT) is a commonly used diagnostic test designed to help your doctor identify retinal diseases such as age-related macular degeneration (AMD) or diabetic retinopathy (diabetic eye disease).

What is the OCT test of your eye?

Optical coherence tomography, or OCT for short, is sometimes referred to as a « 3D » or « digital » eye exam.That’s because OCT involves Take a 3D digital image of the eye. Specifically, OCT takes a cross-sectional image of your retina (the light-sensitive part of your eye).

What can OCT diagnose?

With OCT, doctors can see cross-sections or 3D images of the retina and detect various eye conditions and early onset of eye diseases, such as Macular Degeneration, Glaucoma and Diabetic Retinopathy (The first three diseases known to cause blindness).

What is the principle of OCT?

The functional principle behind OCT imaging is light interference. Therefore, the optical interference device is the heart of any OCT system.

Do optometrists use OCT?

Spectral Domain Optical Coherence Tomography (SD-OCT) is fast becoming a must-have for optometrists.OCT is Standard of care for detecting diabetic macular edema And is the fastest and least invasive way to detect fluid in the retina.

Two types of OCT are commonly used, Time Domain (TD-OCT) and Fourier Domain (FD-OCT).

What is the purpose of optical coherence tomography?

Optical coherence tomography is a Non-invasive imaging technique for obtaining high-resolution retinal cross-sectional images. The layers within the retina can be distinguished, and retinal thickness can be measured to aid in the early detection and diagnosis of retinal diseases and conditions.

What are the advantages of OCT?
