The Coggeshall Eye Centre
Introducing Ocular Coherence Tomography (OCT)
What is an OCT scan?
OCT is a way to image the structures of the inside of the eye using light waves. Instead of looking just at the surface layer of the eye an OCT scan allows us to look deeper and examine the individual layers of the retina and optic nerve in detail. It assists your optometrist in the diagnosis and monitoring of many eye conditions such as Glaucoma, Macular degeneration and Diabetic retinopathy, and many others.
Is it uncomfortable?
Not at all, the scan only takes a few seconds on each eye.
Why do I need an OCT scan
Even if your eyes are perfectly healthy an OCT scan allows us to take baseline measurements of the structures inside your eyes and these can be compared in future scans so even small changes can be detected which would not be possible with visual examination. Early detection of conditions like macular degeneration are possible which may allow you to make lifestyle or dietary changes which can prevent the condition from worsening. Similarly comparing consecutive scans can allow very early changes at the optic nerve to be detected which could indicate you may be at risk of developing Glaucoma.
Is there a charge for this
An OCT scan is part of our private eye test without additional charge however you can still have a scan if you have an NHS eye test but there will be an additional charge for this. Please ask in the practice at the time of your eye test.
