OCT for macular changes and glaucoma assessment

Optical coherence tomography (OCT) is a non-invasive imaging test. OCT uses light waves to take cross-section pictures of your retina.

Optical Coherence Tomography for the investigation of eye problems:

OCT is used to assess the central part of the eyesight for macular function, an Amsler chart is often used for home monitoring. this should be used every week, one eye at a time whilst wearing reading glasses. if distortion is noticed please call us asap. if you are using an Amsler chart you should also take macular supplements, AREDS 2 compliant, such as Macusave.

Epiretinal Membrane (ERM)

OCT scan below is showing an epiretinal membrane (ERM), that is the thin bright line at the top of the scan. these are more common in nearsighted eyes and can pull on the macula leading to distortion of the central vision. ERMs tend to be slow in developing and some do not require treatment.

OCT Scan - Macula

OCT scan below is showing a normal scan of the central part if the vision, the macula. Some patients have changes in the structure of this area which can affect the vision. The bright white line at the bottom of the image is the retinal pigment epithelium (RPE) this is elevated in macular degeneration, in dry and in wet macular changes. The treatment for dry and wet is very different, it is critical to differentiate between the two conditions. Dry macular changes are slow and can benefit from macusave or similar tables. Wet macular changes have to be treated at the eye clinic.

Dry Macular Changes

OCT scan below is showing dry macular changes, the RPE is elevated, but there is no fluid above the RPE. this condition generally has slow progression and benefits from ocular supplements such as macusave.

OCT Showing A Macular Hole

OCT scan below is showing a macular hole, this is caused by traction from the vitreous gel pulling the macula out of shape. this condition can be treated very successfully if diagnosed in time.

OCT Scan Showing Wet Exudative Macular Change

OCT scan below is showing wet exudative macular change, the RPE is elevated and there is fluid just above it, either under the photoreceptors, in this case or also fluild higher up in the retina.

Wet Exudative Macular Change Fluid Reduction

OCT scan below is showing wet exudative macular change on the first image, there is a black space just above the RPE, this is fluid and can be treated at the eye clinic. the second image shows a significant reduction in fluid.

Zeiss OCT

The image below is our Zeiss OCT. The camera does not flash and we can often take good quality images from the centre of your eye without using eye drops, so you can drive back home after the examination. There is a flat screen display by our OCT so you can see the results straight away.

Where To Get Your OCT Scan

Our OCT is in the Earls Colne practice and is on the ground floor.

What Is OCT?

With OCT, your ophthalmologist can see each of the retina’s distinctive layers. This allows your ophthalmologist to map and measure their thickness. These measurements help with diagnosis. They also provide treatment guidance for glaucoma and diseases of the retina. These retinal diseases include age-related macular degeneration (AMD) and diabetic eye disease.
