What Is Optical Coherence Tomography (OCT) Used For?

Advancements in eye care technology have made it easier than ever to detect, monitor, and manage eye conditions before they affect your vision. One of the most important diagnostic tools used in modern optometry is Optical Coherence Tomography, commonly known as OCT. At Texas State Optical Pearland, OCT imaging plays a key role in protecting long-term eye health through early and accurate diagnosis.

What Is Optical Coherence Tomography (OCT)?

Optical Coherence Tomography is a non-invasive imaging test that captures highly detailed, cross-sectional images of the retina and optic nerve. Using light waves, OCT allows your eye doctor to see the distinct layers of the retina without touching the eye. The test is fast, painless, and does not require any recovery time, making it an ideal tool for both routine eye exams and medical evaluations.

OCT is primarily used to detect, diagnose, and monitor eye diseases that affect the retina and optic nerve. These structures are critical for clear vision, and damage can occur long before noticeable symptoms appear.

Detecting and Monitoring Glaucoma

One of the most common uses of OCT is for glaucoma detection and management. OCT measures the thickness of the optic nerve fibers, helping eye doctors identify early nerve damage - even before vision loss occurs. This allows for earlier treatment and better long-term outcomes.

Diagnosing Macular Degeneration

OCT is essential for diagnosing and tracking age-related macular degeneration (AMD). It helps identify fluid buildup, retinal thinning, or structural changes in the macula, which is responsible for sharp central vision.

Evaluating Diabetic Eye Disease

For patients with diabetes, OCT is a critical tool for detecting diabetic retinopathy and diabetic macular edema. It can reveal swelling or fluid in the retina that may not yet be affecting vision but requires prompt treatment.

Assessing Retinal Conditions

OCT is also used to evaluate a variety of retinal issues, including:

•           Macular holes

•           Epiretinal membranes

•           Retinal tears or swelling

•           Inherited retinal disorders

By closely monitoring these conditions, your eye doctor can determine whether treatment is needed and track how well it is working.

What to Expect During an OCT Scan

An OCT scan is quick and comfortable:

•           You’ll rest your chin on a support and look at a target light

•           The machine scans your eyes in just a few seconds

•           No contact is made with your eyes

•           Results are available immediately for your doctor to review

In some cases, pupil dilation may be recommended for optimal imaging.
