Optical Coherence Tomography (OCT)

Non-Invasive, High-Definition Imaging of the Eye's Interior

**Optical Coherence Tomography (OCT)** is a powerful, non-contact imaging technology that uses light waves to capture high-resolution, cross-sectional (3D) images of the retina and optic nerve. It is often described as a **"biopsy without touching the tissue."**

The OCT is indispensable for the modern diagnosis and management of serious eye conditions. It allows our specialists to precisely measure the thickness of the retina and the nerve fiber layer, essential for detecting fluid, swelling, and nerve damage caused by **Diabetic Eye Disease, Macular Degeneration (AMD)**, and **Glaucoma**.

OCT for Macular Diseases

Retina & Macula Analysis

Precise detection and measurement of swelling (**Macular Edema**) and fluid pockets in the macula.

OCT for Glaucoma

Glaucoma Monitoring

Accurate tracking of the thickness of the **Retinal Nerve Fiber Layer (RNFL)** to detect subtle, early glaucoma damage.

Non-invasive eye scan

Painless & Non-Invasive

The test is performed quickly, requires no touching of the eye, and is safe for all patients.

3D retinal scan

3D Visualization

Provides detailed, three-dimensional views, crucial for planning treatments like retinal injections and laser therapy.

Frequently Asked Questions About OCT Scans

OCT technology uses low-coherence light to produce high-resolution, cross-sectional images. Think of it like an ultrasound, but instead of sound waves, it uses light waves to create a map of the different layers of the retina.

In most cases, modern OCT machines can capture clear images without dilation. However, if your doctor needs to check the very periphery of your retina or your pupils are very small, dilation may still be necessary for a full exam.

OCT is critical for monitoring the progression of **Diabetic Macular Edema**, assessing the activity of **Wet Age-related Macular Degeneration (AMD)**, diagnosing and tracking the progression of **Glaucoma**, and identifying macular holes or epiretinal membranes.

The actual scanning process is very fast, usually taking only about **30 seconds to 1 minute** per eye. The patient simply looks at a target light while the scan is performed.
