Optical Coherence Tomography Angiography (OCTA)
Optical Coherence Tomography Angiography (OCTA) is a modern, non-invasive method used for detailed examination of the retinal and choroidal vessels (the inner part of the eye). This technology helps us, ophthalmologists, diagnose and monitor various eye conditions with greater accuracy.
Common Conditions Detected by OCTA
OCTA is particularly useful in diagnosing and monitoring:
– Age-related Macular Degeneration (AMD): It detects and monitors the formation of neovascularization and damage in the macula.
– Diabetic Retinopathy: It helps identify microaneurysms and neovascularization.
– Glaucoma: It examines changes in the structure of nerves and the retina.
– Retinal Vascular Occlusions: It records changes in blood circulation and vascular damage.
What is OCT Angiography?
OCT Angiography uses light to create detailed images of the vessels at the back of the eye. Unlike traditional angiographies, it does not require the injection of a dye into the patient's vein, making the procedure more comfortable and safer for the patient.
How Does It Work?
1. No Dye Injection: OCT Angiography uses light to scan the eye and record blood vessels, without the need for fluorescein or indocyanine dye injection.
2. Accurate Images: It creates detailed images of the retinal and choroidal layers and blood vessels.
3. Safe and Comfortable: The procedure is quick, painless, and non-invasive, ideal for patients of all ages.
The Procedure
1. Preparation: The patient sits in front of the OCT machine and positions their head steadily.
2. Scanning: The doctor directs a light beam in front of the patient's eye without making contact. The patient simply looks at the light.
3. Imaging: The machine records detailed images of the retinal layers and vessels.
4. Analysis: The doctor analyzes the images to detect any abnormalities and diagnose conditions.
Why Choose OCT Angiography?
– No Dye Needed: Eliminates the risk of allergic reactions.
– Comfort: The procedure is quick and painless.
– Accuracy: Provides high-resolution images for more precise diagnosis and monitoring.
– Preventive Care: Allows early diagnosis and monitoring of conditions, preventing further deterioration.
OCT Angiography is a valuable tool in ophthalmology that allows for accurate and safe diagnosis and monitoring of many eye conditions. If you have any questions or concerns about your eye health, consult your ophthalmologist to see if OCT Angiography is suitable for you.
