Slit lamp biomicroscopy allows the evaluation of the anterior segment in microscopic details when there is corneal and media transparency. Special gonioscopy lenses allow the ophthalmologist to examine the angle recess area, which is possible in clear media. Knowledge and understanding of the anatomic variations and pathologic conditions of the anterior segment enables better therapeutic decisions and, in the case of corneal or refractive surgery, permits appropriate surgical procedures to be devised.

Corneal lamellar surgeries, laser surgeries, and intraocular lenses implants are surgical modalities which require detailed measurements of the anterior chamber anatomy in order to program the surgery and to allow adequate postoperative care.

There is also a concern about conditions that affect areas of the anterior segment that are difficult to assess with slit lamp biomicroscopy, such as the posterior part of the iris, the posterior chamber, ciliary body, and zonulae.

Modern standards of care in medicine require serial evaluation, documentation, and measurement for lesions such as cysts, nevi, and tumors. Glaucoma can be classified based on the position of the iris related to the angle recess and the ciliary body, thus allowing adequate therapeutic management.

Ophthalmology requirements changed in time; therefore, high-frequency ultrasound and anterior segment optical coherence tomography have settled their usefulness in detailing the anatomy of the anterior segment, qualitatively and quantitatively.

We invite authors to contribute sending original research articles as well as review articles that explore aspects of the anterior segment imaging in humans and also in animal models. Potential topics include, but are not limited to:

• Comparison of both techniques for anterior segment evaluation: anterior segment OCT and high-frequency ultrasound or UBM
• Anterior segment OCT recent modalities: 3D-AS-OCT, Doppler, high speed, SD-OCT, artifacts, signal processing
• Anterior segment ultrasound or ultrasound biomicroscopy (UBM) or high-frequency ultrasound (HFUS) improvements: 20, 35, 50, 75, 100 MHz, modified immersion devices, arc scan, 3D, Doppler, artifacts
• Research in ultrasound transducers and in OCT image enhancement
• Blood flow analysis of ciliary body and iris
• Tissue characterization using AS-OCT and AS-US
