What is OCT?

OCT stands for optical coherance tomography and we are delighted to have recently got one installed in OC eyecare! Our optometrist Orlagh has had 6 years previous experience working with the fantastic technology that OCT brings. Having seen first hand the many benefits of having an OCT in practice we have chosen to offer this service to our patients.

An OCT scan takes a 3D image of the back of the eye and it allows us to view the different layers of the eye in detail. Previously with a retinal photograph we were only able to view the surface of the eye. It is routinely used in a hospital eyecare setting, specifically in the macular clinics. An OCT scan only takes a matter of seconds and is non-invasive, the results then will be explained in lay-man terms to the patient.

OCT scans can help detect sight-threatening eye conditions earlier. Essentially, an OCT scan gives your optician a clearer idea of your eye health when testing your eyes. Your OCT is kept as a baseline scan therefore you optician can compare and refer back to the scans at each eye exam to note small changes.

Who should get an OCT?

In short everyone. These small changes would be difficult to track with the naked eye, as the OCT takes many numerical measurements. This is particularly important in the early detection of Glaucoma as it progresses very slowly. Glaucoma rarely displays symptoms until it is too advanced and this damage is irreversible. This means that conditions like these can be managed before they get worse and can help prevent potential sight loss.

What conditions can an OCT detect?

Due to the pandemic a lot of hospital eye service appointments have been either cancelled or delayed. Including the the diabetic retinopathy screening, these delays will have a detrimental effect on many patients eye health. With the advancement of online referrals OCT scans can be sent directly to ophthalmologists without having to attend a hospital appointment.
