Our OCT scanner can spot health problems as well as eye conditions at an early stage
At Heather Bailey Optometrists we believe in premium eye care. We want to deliver you with the most thorough eye examination possible and the way we ensure that we do this is by offering OCT scanning.
An OCT scanner is an advanced piece of technology that allows us to take quick and painless images of the parts of your eye that can’t be seen. A series of snapshots are taken of your retina (and other parts of the back of your eye) before being combined to create a 3D, cross sectional view of it. The optician is then able to examine the image in great detail to look for even the smallest indication that you could have a problem.
OCT images have up to 25 times better resolution than those produced by any other imaging technology. This means that not only are the images clear enough to identify eye conditions, but they can also reveal health problems such as diabetes and cancer too.
It’s important to remember that the earlier eye and health conditions are diagnosed, the more likely effective treatment is. For that reason we strongly recommend that you have your eyes scanned by the OCT annually, especially if you are over 40, and therefore at a higher risk of developing certain eye diseases.
Conditions that are commonly identified through the use of OCT scanning are:
Age Related Macular Degeneration (ARMD)
Macular degeneration causes a gradual breakdown of the macula (central portion of eye). OCT can identify this condition, which type it is (wet or dry), and monitor its progress. This is the most common cause of vision loss in individuals over the age of 50
Glaucoma damages the optic nerve at the point where it leaves the eye. Statistics show that some form of glaucoma affects around 2 in every 100 people over the age of 40. The danger with chronic glaucoma is that there is no pain and your eyesight can seem to be unchanged. An OCT can confirm which stage of glaucoma you might have, as well as whether or not you’re at risk of developing it in the future.
This is a hole in the part of the retina that gives you your sharp detailed central vision. You use this vision when you are looking directly at things, when you’re reading, sewing or using the computer. There are many causes of macular holes. One is vitreous detachment; when the vitreous pulls away from the back of the eye and sometimes doesn’t let go, eventually tearing the retina leaving a hole. Extreme exposure to sunlight (looking at an eclipse) can also sometimes cause a hole.
As people get older, the vitreous jelly that makes up the shape of the ball of the eye can change. It can become less firm and move away from the back of the eye towards the centre. In some cases parts do not detach and cause a ‘pulling’ of the retinal surface leading to a detached retina. The danger of a vitreous detachment is that there is no pain and your eyesight will seem unchanged. However the back of your eye could be suffering damage.
Diabetic retinopathy is a major cause of visual impairment among adults. The OCT enables early detection of the condition.
