Optical Coherence Tomography (OCT) is an advanced imaging technology used in medicine to obtain high-resolution, cross-sectional images of biological tissues. It employs light waves to capture detailed images of the eye, specifically the retina, allowing for precise analysis of its layers and structures. This non-invasive imaging technique is instrumental in diagnosing various eye conditions and monitoring changes in eye health over time.
What are the benefits?
- Early Detection and Diagnosis: OCT enables early detection of eye diseases like macular degeneration, diabetic retinopathy, and glaucoma, aiding in timely treatment and better management.
- High Precision Imaging: It provides highly detailed, three-dimensional images, allowing eye care professionals to visualise subtle changes in the retina and identify abnormalities.
- Monitoring Progression: OCT helps track disease progression, facilitating more personalised treatment plans and interventions.
- Non-invasive Procedure: It is a non-contact and painless procedure, making it comfortable for patients of all ages.
What does it involve?
During an OCT examination, the patient sits in front of the OCT machine. The process typically involves the following steps:
- Preparation: The patient may have eye drops administered to dilate the pupils, enhancing the quality of the images.
- Image Capture: The patient places their chin on a support to maintain stability while a scanner captures detailed images of the eye’s structures using light waves.
- Analysis: The captured images are processed and analysed by a specialist to evaluate the health of the retina and detect any abnormalities.
The procedure is relatively quick, taking only a few minutes per eye.
Who is it suitable for?
OCT is suitable for individuals who:
- Have or are at risk of developing eye conditions such as macular degeneration, diabetic retinopathy, glaucoma, or other retinal disorders.
- Need monitoring for changes in their eye health.
- Are undergoing treatment for eye conditions to assess the effectiveness of the therapy.
- Require detailed imaging for a comprehensive assessment of their eye health.
Optical Coherence Tomography has revolutionised the field of ophthalmology, providing invaluable insights into eye health and playing a crucial role in early detection, diagnosis, and management of various ocular conditions.
