OCT Optical Coherence Tomography

OCT (Optical Coherence Tomography) is a scan used to examine the layers of the retina. The retina is the light sensitive area at the back of the eye, equivalent to film in a camera.

Introduction

An OCT is a scan which takes 3D images of the layers of the retina. The scan allows your retinal specialist to see the structures in the retina that may not be visible with direct examination.

The Procedure

The test is very simple and just takes fifteen to twenty minutes.

It is a completely non contact test. There are no puffs of air or light flashes into your eyes.

Your pupils will be dilated and so you can expect that your vision will be blurred for 4-6 hours afterwards.

This test may be used to diagnose certain eye conditions and to help plan treatment.

Following The Procedure

As your pupils will have been dilated, your vision will be blurred for 4-6 hours afterwards.

You should have someone ready to accompany you home.

Do not drive after the scan.

OCT scans may need to be repeated regularly to monitor response to treatments or changes in your eye condition.
