Abstract:

 Biological measurement of the anterior chamber plays an important role in the diagnosis and treatment in the ophthalmology field, especially in glaucoma， cataract surgery and corneal diseases. Effort to improve the image of the anterior chamber has promoted the development of numerous imaging modalities. The main techniques used for imaging the anterior segment are Pentacam-Scheimpflug， anterior chamber-optical coherence tomography， Orbscan scanning-slit topography and ultrasound bio-microscope. All devices promise quantitative information and qualitative imaging of central anterior chamber depth, perimeter anterior chamber depth and anterior angle. In this paper, a selection of recent advances for the anterior chamber on principles, characters of anterior chamber imaging and their clinical application were reviewed.
