There is a lot of equipment your eye doctor in Alexandria, VA, can use to better understand the state of your eyes. The Optical Coherence Tomography, for example, is an imaging test used to get clear pictures of your retina. By learning more about the test, you may become more comfortable when it is performed.
About the Test
OCT uses light waves to get images of the different layers of your retina. These cross-sections may help your optometrist measure the thickness of each layer. Often this test requires your pupils to be dilated, so the retina is easier to examine.
The test itself is noninvasive. You simply have to rest your chin on a head rest in order to assure your head is kept motionless. The OCT will then start scanning your eyes for about five or 10 minutes. Once the scan is complete, your eye doctor will be able to assess the images. Not all optometrists will use this type of equipment. You may need to search for ‘an optometrist near me with optical coherence tomography’ to find an eye doctor who uses this equipment.
What It Tests
OCT may be able to help diagnose certain eye conditions and disorders of the optic nerve, such as:
- Diabetic Retinopathy
- Age-Related Macular Degeneration
- Preretinal Membranes
- Central Serous Retinopathy
- Macular Hole
Because this test helps measure the thickness of each layer of your retina, the doctor may be able to use this test to help set up a treatment plan for any eye diseases you may have. This test may not have to be done during every eye exam in Alexandria.
It can be hard to understand exactly why this eye exam equipment is used. If you have questions about OCT, or any other type of equipment, be sure to talk with your eye doctor in Alexandria, VA. He or she will be able to address your concerns related to the testing done during your exam.
