Optometrist explaining an eye test

OCT Eye Tests Explained

OCT eye tests give you a far more detailed image of your eye. This allows us to go into greater depth when assessing the health of your eyes. More detail means we can identify potential eye conditions that would be missed during a normal exam.

At Eyesite, we believe in providing you with the best possible eye care. To #loveyoureyes properly, we need to get a really good look at them. That’s why we use OCT imaging to create a detailed, 3D scan of the tissue that lines your eye.
This state-of-the-art 3D technology takes 128 individual high res scans of the back of the eye, and creates a detailed picture of either the optic nerve or the macula (central vision area). Every distinctive layer of the retina can be seen using these scans.

Benefits of an OCT Eye Test

  • Gives us the best view of your eye
  • Non-invasive and completely painless
  • It only takes around 10 minutes
  • Nothing touches the eye
  • Identifies a wide range of conditions

Our talented optometrists then use this photographic information to map and measure the thickness of these individual layers. This is what helps us to identify, diagnose and provide treatment for eye conditions such as glaucoma, age-related macular degeneration and diabetic eye disease.

OCT eye tests can diagnose a range of conditions

The 128 scans that make up an OCT scan allow us to look at every layer of your eye tissue. This allows us to identify a range of potential eye problems, including:

The importance of OCT eye tests

Many of the conditions that can be identified with OCT imaging are easily treated when caught early, which is part of what makes OCT eye tests so important.
AMD is the most common cause of blindness in the over 50 age group in western society. Wet AMD can cause sudden loss of sight over a matter of days, fortunately it is less common than Dry AMD, which is more gradual. OCT can not only identify which type of AMD is present but can monitor progress if you are undergoing treatment.

Macular damage is rare, but if caught early can be treated successfully. If untreated, macular holes affect the very centre of your vision. OCT clearly shows even very early macular holes when they are invisible with conventional viewing techniques.

OCT imaging also scans the optic nerve, allowing us to see any damage or monitor the progression of conditions like glaucoma more accurately.

Once you’ve had an OCT eye test, the images can be easily and securely archived to create a library of your eye health, documenting the changes over time. This comprehensive record of your optical health allows us to make the most accurate diagnoses possible and make any necessary referrals simple.
