Optical Coherence Tomography

What Is Optical Coherence Tomography

Optical Coherence Tomography is one of the preferred ways of developing and recording image of the retina of the eye. Retina is the part of the eye that captures the light entering the eye and develops an image. Thus, retina is one of the most important parts of the eye.

Optical Coherence Tomography is a technique that develops 3D image of the retina. The result is a cross sectional image of the retina that clearly depicts all deformities and issues on the surface and underlying layers of retina.

Since the test reveals the top and all underlying layers of retina tissues, a qualified ophthalmologist is able to detect several abnormalities. Hence, the test is a very important aid in dealing with progressive loss of eyesight. The test is particularly useful for monitoring the progress of age related degeneration of eyesight and the damage caused to the structure of the eye by diabetes.

The Procedure Of Optical Coherence Tomography

The equipment used for the test resembles other eye exam machines. The process starts with the technician using eye drops to dilate the eye. After the medication has taken effect, the pupils become fully dilated. The patient is asked to sit before the OCT machine. The process is non invasive and the equipment does not touch the eyes. The patient might see bright flashes of light during the test/ once the test is complete the patient could go home without any delays or issues.
