OPTICAL COHERENCE TOMOGRAPHY

Optical Coherence Tomography is a non-invasive imaging service that produces high-resolution cross-sectional scans of the retina and optic nerve. It uses low-coherence light waves to measure tissue layers in microns. As a result, your ophthalmologist can detect, document, and monitor many sight-threatening conditions with strong precision and repeatability.

WHAT THIS SERVICE DOES

This scan works like an optical ultrasound that uses light instead of sound. It generates detailed layer-by-layer images of the retina, macula, and optic nerve head. Therefore, it reveals swelling, thinning, traction, and fluid that may not be visible on routine examination alone. In addition, quantitative measurements allow objective comparison across visits.

COMMON CLINICAL USES

Doctors request Optical Coherence Tomography when structural retinal or optic nerve information is required for diagnosis or follow-up. For example, it supports both medical and surgical decision-making.

1. Macular degeneration assessment and monitoring
2. Diabetic macular edema detection
3. Glaucoma optic nerve and nerve fiber analysis
4. Epiretinal membrane and vitreomacular traction evaluation
5. Central serous chorioretinopathy monitoring
6. Unexplained vision loss investigation

HOW THE SCAN IS PERFORMED

The procedure is quick and comfortable. First, you sit at the OCT device and place your chin on a support. Next, you focus on an internal target while the scanner captures images in seconds. Nothing touches the eye during capture. Consequently, the test remains comfortable and low risk. In many cases, dilation is not required, although it may improve image quality in selected patients.

PATIENT COMFORT AND SAFETY

Optical Coherence Tomography uses safe, low-power light and does not involve radiation or injections. Because the scan is non-contact, infection risk is minimal. Most patients complete the test easily. Moreover, normal activities can continue right after imaging unless dilation drops are used.

WHY EARLY STRUCTURAL DETECTION MATTERS

Many retinal and optic nerve diseases begin with microscopic structural change before major vision loss occurs. Early detection allows earlier treatment and closer monitoring. Therefore, OCT supports timely intervention and more personalized care. Objective imaging also improves long-term disease tracking and treatment response evaluation.
