An eye examination is much more than checking your prescription and updating your glasses. Using our state-of-the-art technology, we can gain a deeper insight into the health of the eye in more detail than the human eye can see.

At Bush, we have two pieces of equipment which enable us to do this, the Optomap and optical coherence tomography (OCT). Both are non-invasive and allow our optometrists to get a clear view of the eye health and diagnose any eye conditions in its earliest stages.


The Optomap is a retinal scan that examines up to 80% of the retina compared to the 20% which can be seen by the human eye. It is a painless process that takes hardly any time at all and can provide the optometrist with a lot of information about the health of your eyes, and the best course of action should an eye condition or non-eye disease such as diabetes, be detected.

The OCT uses light waves to take cross section pictures of the retina, resulting in a 3D image of the layers of the retina. This allows our optometrists to map and measure their thickness, which is essential for the early detection and treatment guidance for retinal diseases such as macular degeneration, diabetic eye disease and glaucoma. The OCT is also often used to evaluate changes to the optic nerve where increases in blood pressure can cause damage to the nerves.

Including the Optomap and OCT as part of your regular eye examinations is advised as this will build a record of your eye health and allows the optometrist to monitor this for any changes. By including these scans in your eye examination, we can provide you with one of the best comprehensive and thorough eye examinations.
