What Conditions Can an Optical Coherence Tomography (OCT) Scan Detect?

Modern eye care relies on advanced technology to detect vision-threatening conditions early - often before symptoms appear. One of the most valuable diagnostic tools your eye doctor may use is Optical Coherence Tomography (OCT). At Texas State Optical, OCT scans play a critical role in monitoring eye health and preserving vision.

What Is an OCT Scan?

An Optical Coherence Tomography scan is a non-invasive imaging test that captures detailed cross-sectional images of the retina and optic nerve. Using light waves, OCT allows your eye doctor to see the individual layers of the retina - structures that cannot be viewed clearly with a standard eye exam alone. Because of its precision, OCT is often used for early detection, diagnosis, and ongoing monitoring of eye diseases.

Glaucoma

OCT scans measure the thickness of the retinal nerve fiber layer and optic nerve. Thinning in these areas can indicate glaucoma - even before noticeable vision loss occurs. OCT is essential for:

• Early detection

• Tracking disease progression

• Evaluating treatment effectiveness

Macular Degeneration (AMD)

Age-related macular degeneration affects the central retina (macula), which is responsible for detailed vision. OCT helps detect:

• Early structural changes

• Fluid buildup or retinal thinning

• Progression from dry to wet AMD

Early diagnosis allows for faster intervention and better vision preservation.

Diabetic Retinopathy

For patients with diabetes, OCT is a key tool for identifying:

• Diabetic macular edema (retinal swelling)

• Fluid leakage

• Retinal thickening or damage

Even when vision seems normal, OCT can reveal changes that require prompt treatment.

Who Should Have an OCT Scan?

Your eye doctor may recommend an OCT scan if you:

• Have diabetes or glaucoma

• Are at risk for macular degeneration

• Experience unexplained vision changes

• Have a family history of eye disease

• Need ongoing monitoring of a diagnosed condition

The test is quick, painless, and requires no direct contact with the eye.

Prioritize Your Eye Health Today

An Optical Coherence Tomography scan is one of the most powerful tools in modern eye care. By revealing microscopic changes in the retina and optic nerve, OCT allows eye doctors to detect serious conditions early. Early diagnosis means earlier treatment, better outcomes, and long-term vision protection.
