| Abstract | Optical coherence tomography (OCT) is a new diagnostic tool to image biological tissue with high resolving power. The operation of OCT is similar to that of ultrasound B-scan imaging except it utilizes light waves rather than acoustic sound waves. Because of this difference, the axial resolution of OCT is as high as 10 μm, compared with 150 μm of that of a conventional 10-MHz B-scan ultrasound. OCT is a non-contact examination, which improves patient comfort and allows the test to be performed in less time. For certain conditions such as age-related macular degeneration, OCT is able to reduce or eliminate the need for fluorescein angiography for some patients. The main use of OCT has been in the posterior segment, although some investigators have reported its usefulness in documenting anterior segment pathology. |
