[Spectral-domain optical coherence tomography in anterior segment imaging: the 3rd dimension].

Purpose: Anterior segment imaging using optical coherence tomography (OCT) time domain technology has been used for many years. When it appeared, it was a promising technique in the analysis of the anterior segment, making it possible to reach a definition of the ocular structures comparable with histology. Now with new-generation OCT, it is possible to perform high-definition and three-dimensional imaging.

Material And Method: A 3D OCT-1000 (Topcon, Tokyo, Japan) parameterized to obtain high-definition and 3D imaging of the iridocorneal structures.

Results: We present a collection of images obtained using this technique.

Discussion: Based on a very sophisticated tool for retinal and glaucoma imagery, it is now possible to obtain very-high-quality imaging of the anterior segment, which, with its great versatility, increases the value of acquiring this type of device.

Conclusions: The potential of 3D OCT-1000, already a very good exam for the posterior segment, and the only one to perform anterior segment three-dimensional imaging in a single acquisition, should not be neglected.
