Optical coherence tomography (OCT) is a new technique in the diagnosis of eye diseases which uses a lower coherence interferometry to give optical sections in ocular tissues. The principle of OCT, which uses infrared diode laser, is based on the analysis of the time of light delay of optical signals that have been reflected from ocular tissues such as the retina. It has the advantage of being non invasive, non contact, comfortable and well tolerated by the patient. It doesn’t require dye injection or radiation exposure. Despite the presence of other diagnostic modalities of macular hole such as ultrasonography, fundus fluorescein angiography scanning laser ophthalmoscope and laser biomicroscope, OCT appears potentially useful as a new diagnostic technique for visualizing and quantitatively characterizing macular holes and assessing fellow eyes of patients with a macular hole. The tomographic information provided by OCT may lead to a better understanding of the pathogenesis of macular hole formation. It may help in staging macular holes, its differentiating from other mimicking conditions as well as possibly predicting the visual outcome following macular hole surgery.
