Abstract

Several limitations have been encountered with the reference standard of gonioscopy for angle assessment. Advancements in ophthalmic imaging technologies, especially anterior segment optical coherence tomography (AS-OCT) in recent years, have established robust, reliable, and quantitative protocols to examine the structure of the anterior segment with proven usefulness to detect various ocular complications including angle closure. The goal of this chapter is to review the basics of the most commonly used anterior segment imaging techniques (ultrasound biomicroscopy and AS-OCT), including a concise update of how they work and how objective and quantitative evaluation can be conducted in clinical practice.
