Visit your Optometrist or eye care professional to learn more about retinal imaging and the benefits of early detection for eye conditions and diseases. The macular thickness test is not as sensitive as the nerve fiber thinning. Manufactured by Carl Zeiss Meditec, and originally used as a research tool, OCT has drawn ophthalmologists to buy thousands of subsequent iterations. It can cause blindness but it normally progresses slowly and can be treated with special eye drops to lower the pressure caused by the fluid. Optical coherence tomography may not be as pervasive as the ophthalmoscope, but it has definitely gone mainstream. It typically happens when fluid builds up in the front of your eye. Many optical practices now offer the option of having an optical coherence tomography (OCT) scan, alongside your sight test, or during a separate visit. Glaucoma : This disease damages your optic nerve (located in the retina) and may cause vision loss. ![]() Retinal imaging is very important in finding this type of macular degeneration. Abnormal blood vessels growing under the retina cause wet macular degeneration. It happens when blood vessels under the retina become thin and brittle. No radiation or X-rays are used in this test, an OCT scan does not hurt and it is not uncomfortable. There are two kinds of macular degeneration: wet and dry.ĭry macular degeneration is by far the most common form of this disease (up to 90% of the cases).

If your doctor thinks you have age-related macular degeneration, they may want you to have one or both of these tests: Optical coherence tomography (OCT). You may have blurry vision and find it harder to focus. These include diabetic retinopathy, macular holes.
