OCT Retinal Scan
Many common eye diseases can creep up on you, without any significant symptoms. So, even if your vision and eyes appear perfectly fine, it’s useful for your optician to gain a full understanding of your overall eye health through additional tests.
In particular, an OCT scan can help to detect eye conditions like glaucoma, age-related macular degeneration and diabetic retinopathy. Your optician may recommend that you attend an OCT scan even when your eyes are healthy in order to provide a baseline image.
An OCT scan can help your optician to see what’s going on beneath the surface of your eye, providing a picture of the layers of your retina. Your optician can then map out the layers and measure the thickness. The optic nerve head is also visible at the back of your eye, so an OCT scan can also evaluate any disorders of the optic nerve.
