Optical Coherence Tomography (OCT)

Apple Ophthalmology offers comfortable, non-contact OCT tests.  Optical Coherence Tomography (OCT) is a non-invasive imaging test that uses light waves to take cross-sectional pictures of the retina, the light-sensitive tissue lining the back of the eye. This advanced imaging technique provides high-resolution, three-dimensional images that allow ophthalmologists to see the different layers of the retina with exceptional detail. It has become an essential tool in the diagnosis and management of various eye conditions, offering insights that were not possible with earlier imaging technologies.

How OCT Works

OCT operates on the principle of low-coherence interferometry. It emits near-infrared light towards the retina, which is then reflected back and captured by the OCT device. The time delay and intensity of this reflected light are measured and used to construct detailed cross-sectional images of the retina. These images can be analyzed to understand the thickness, structure, and composition of the retinal layers.

Advantages of OCT

OCT has revolutionized eye care, enabling early detection of eye diseases and precise monitoring of treatment outcomes. Its ability to provide detailed images of the retina and optic nerve makes it an invaluable tool in the field of ophthalmology.
