Title: Anterior Segment OCT: How to Choose for Your Practice
Abstract: Anterior segment optical coherence tomography (AS-OCT) is a noncontact noninvasive method for the evaluation of the anterior segment structures that uses low-coherence interferometry to produce cross-sectional images and provide quantitative measurements. There has been a rapid development of OCT technology over the years, with transition from time domain OCT (TD-OCT) to Fourier domain (FD-OCT) devices, which are further subcategorized into spectral domain OCT (SD-OCT) and swept-source OCT (SS-OCT). SD-OCT tends to provide generally better axial resolution of the cornea but worse angle imaging when compared to SS-OCT, whereas the latter provides better signal quality with depth and angle visualization, but it is generally more expensive. The AS-OCT technology currently has a major role in clinical and research applications in ophthalmology. The advancement of AS-OCT technology has been evolving; improvements in resolution and acquisition speed have enhanced the image quality and reproducibility for anterior segment imaging with greater detail. This chapter summarizes the AS-OCT technologies available and compares their performance.
