Optical ocular tomography - new coherent wave in ocular diagnosis

stratusoctThe advent of the most recent diagnostic technique using a coherent light waves promises to revolutionize eye condition study or detection. It is compared to that with the ultrasound sonography in some ways or the other but a small technical difference. In the later sound waves are utilised for detection while in case of Optical Ocular Tomography coherent light waves are used.

Tomography refers to the technique of taking photographs of the living surfaces or organs. In the case of Optical Ocular Tomography the device is sending coherent waves on the retina generally and obtaining a picture of it within the timespan of 2.5 seconds. Moreover it is a non- invasive, non- contact type diagnostic treatment unlike its predecessors as fundus examination and fluorescein angiography

The technique mainly depends on the principle of "time of flight delay". It is taking the image from the backscattered lights obtained from the retina. This helps to detect diseases as full- and partial-thickness macular hole, epiretinal membrane, macular edema, intraretinal exudate, idiopathic central serous chorioretinopathy, and detachments of the pigment epithelium and neurosensory retina.

It is reported to have a high depth resolution (10 microns) cross-sectional tomographs of ocular tissue.

Optical coherence tomography is potentially a powerful tool for detecting and monitoring a variety of macular diseases, including macular edema, macular holes, and detachments of the neurosensory retina and pigment epithelium. It is to be reminded in this point that dont get confused with this term "Optical Coherence Tomography". It is same as "Optical Ocular Tomography".

Still now we have not received the technical details of the technique and we are in search of it. As soon as it is available we will let you know.
