How OCT Scans Are Changing The Optical Eye Test Industry 

May 11, 2022 | Eye Health

When it comes to testing the health of our eyes, there have been significant advancements in technology in recent years. OCT (Optical Coherence Tomography) scans are a breakthrough in the medical industry and have helped improve the effectiveness of eye tests.  

Available clinically since 2006, these scans have changed the way eye tests are conducted for the better, providing eye care professionals with a detailed view of the individual layers of the eye.  

This article will explore why OCT scans are vital for optical eye test patients and how they contribute to early detection, accurate diagnosis, and effective treatment of various eye conditions.  

What is an OCT scan? 

OCT scans use light waves to produce high-resolution, cross-sectional images of the eye. These images are invaluable for eye care experts as they provide a wealth of information that is typically not available through traditional eye testing methods. 

This means experts get a chance to see areas of the eye that are traditionally more difficult to capture, allowing for clearer images of our eye surfaces.  

How do OCT scans work? 

In ophthalmology, OCT scans are widely used to examine the structures in the eye. They provide valuable information about the health of the eye. This allows optometrists to diagnose and monitor eye conditions.  

As well as large changes in the eye, OCT scans can detect subtle changes in these structures, aiding in early disease diagnosis and treatment monitoring. This means optometrists can offer early treatment, preventing the progression of a disease and saving your eye from vision loss. 

Why are OCT scans a game-changer in eye tests? 

Early detection of eye conditions  

One of the primary benefits of OCT scans is their ability to detect eye conditions at the earliest stages, often before noticeable symptoms occur.  

By capturing detailed images of the layers comprising the eye, OCT scans can reveal subtle abnormalities that may indicate the presence of eye diseases. Detecting these conditions early allows for timely intervention, potentially preventing further deterioration and preserving good vision.  

Accurate diagnosis  

With OCT scans, optometrists can confidently diagnose various eye disorders accurately by analysing the intricate details within the images.  

By visualising the various qualities of the eye, OCT scans help to differentiate between different eye conditions that may present similar symptoms. This precise diagnosis leads to more targeted treatments, reducing the risk of unnecessary interventions and ensuring better patient outcomes.  

Progress monitoring and treatment evaluation  

OCT scans are not only used for initial diagnosis but also play a vital role in monitoring the progress of eye conditions and assessing  the effectiveness of a treatment. By comparing successive OCT images, we can track changes in the eye’s structure and identify whether the prescribed treatment is achieving the desired results. This allows optometrists to confidently make the necessary adjustments in treatment.  

Enhanced patient education  

OCT scans also offer patients a unique opportunity to visualise their eye conditions, leading to an improved understanding. OCT scans facilitate clear explanations during consultations, enabling patients to grasp the extent and severity of their conditions.
