Opticians rely on various methods to diagnose and treat conditions that affect your vision, one of which is the Optical Coherence Tomography (OCT) eye test. It is a non-surgical and non-invasive method that uses imaging techniques to capture the cross-section of the retina, or the back of your eye. With this test, the thickness and layers of the retina can be measured, to help diagnose glaucoma, macula degeneration, and other problems.
You might not know the appropriate time for this examination, and only a professional can make that recommendation. It is therefore essential to consult a trusted optician and go for regular visits.
What is an OCT Eye Test?
An Optical Coherence Tomography eye test utilises 3D imagery techniques to examine not only the surface of the retina but the cross-section and other parts of the eye. It is used by opticians or ophthalmologists to examine all the layers of the eye at its core structure in order to detect, monitor, and provide a diagnosis for various conditions.
The testing method provides high-definition 3D scans that doctors can use for the early detection of ocular diseases such as glaucoma, diabetes-related retinopathy, and retinal occlusions.
Here are the three reasons you might need this examination:
Glaucoma is a group of vision impairment conditions caused by factors such as high internal pressure in the eye and diabetes-related medical conditions. Glaucoma causes damage to the optic nerve – the nerve connecting the eye to the brain – leading to vision problems and possible blindness.
An OCT eye test can detect glaucoma for a period ranging from four to five years earlier than other traditional methods. Early detection provides a better chance for diagnosis and can therefore help prevent severe damage.
Macular Degeneration Evaluation
Macular degeneration is a condition that causes damage to the macula, affecting the central vision and, in turn, leading to vision problems. People with this condition have a hard time perceiving finer details (whether looking at something close or far), while side vision remains normal. The common cause of macular degeneration is age, affecting people over the age of 50.
The OCT eye test provides images that allow close examination of the retina and macula to detect changes in size, fluid accumulation, monitor changes over time, and provide an early diagnosis that prevents further progression.
Macular edema also causes damage to the macula, affecting the central vision due to fluid accumulation that causes swelling in the retinal area. Over time, the accumulation of fluid increases the size of the macula, causing blurry and distorted vision. The common cause is due to other conditions such as diabetic retinopathy and inflammation.
The images from the examination can be used to assess changes in the size of the macula, the texture, and fluid accumulation within the retina and the macula. Furthermore, the results can be used to determine the severity of the condition, provide a better diagnosis, identify potential causes, and monitor the progress and effectiveness of the treatment.
The benefits of an OCT eye test are important for diagnosing and treating glaucoma, macular degeneration, and macular edema, all of which can affect our vision and lead to blindness. Monitoring the thickness and layers of the retina can help in the early detection of these diseases and help doctors find a better treatment. It is therefore essential to regularly visit a trusted optician who can recommend and carry out this examination at the appropriate time.
