What is Optical Coherence Tomography (OCT) and Why is It Important?

At Eldorado Vision & Optical, we are committed to offering the latest in eye care technology, and Optical Coherence Tomography (OCT) is one of the most valuable tools in our diagnostic process. But what exactly is OCT, and why is it so important for maintaining your eye health?

What is Optical Coherence Tomography (OCT)?

OCT is a non-invasive imaging technique that captures highly detailed, cross-sectional images of the retina, the light-sensitive tissue at the back of your eye. It works by using light waves to measure the thickness of each retinal layer, allowing your eye doctor to get a 3D view of your eye’s internal structures. OCT can detect subtle changes in the deeper layers of the retina. This precision helps in the early detection of various eye conditions that could affect your vision in the long run.

What Can OCT Detect?

The detailed imaging provided by OCT is invaluable in diagnosing and monitoring a wide range of eye conditions, including:

•       Glaucoma – OCT can measure changes in the thickness of the optic nerve fibers, which is crucial for early detection and monitoring of glaucoma. By catching this condition early, we can help manage it before significant vision loss occurs.

•       Macular Degeneration – Age-related macular degeneration (AMD) is one of the leading causes of vision loss. OCT allows us to see the layers of the macula (the part of the retina responsible for central vision) and detect any abnormalities, such as fluid accumulation or tissue damage.

•       Diabetic Retinopathy – Diabetes can cause damage to the blood vessels in the retina, leading to vision loss. OCT can detect these changes before symptoms appear, allowing for early intervention.

•       Retinal Detachment or Tears – OCT helps in detecting early signs of retinal tears or detachments, which, if left untreated, could lead to permanent vision loss.

•       Cataracts and Other Conditions – While OCT is mainly used to examine the retina, it can also assist in evaluating other eye conditions, such as cataracts, by providing detailed information about the overall health of the eye.

Why is OCT Important?

OCT is essential for early diagnosis and prevention. Many eye conditions, such as glaucoma and macular degeneration, progress without noticeable symptoms in their early stages. By the time you realize something is wrong with your vision, irreversible damage may have already occurred. OCT allows us to detect these conditions before symptoms manifest, giving us the opportunity to create a treatment plan that can slow or halt the progression of the disease.

How Often Should You Have an OCT Scan?

Your need for OCT screening depends on various factors, such as your age, family history of eye disease, and overall eye health. Generally, we recommend that patients over the age of 40, those with diabetes, or anyone with a family history of eye disease get an OCT scan at least once a year. However, your eye doctor will provide personalized recommendations based on your specific needs.
