The second edition of the Sankara Nethralaya atlas of ophthalmic ultrasound, while retaining its original layout and flavor, has considerably widened its scope to include anterior segment imaging using ultrasound biomicroscopy.

The original chapters which involved imaging of the posterior segment and orbit have been updated with addition of many new images, though the techniques of evaluation have remained unchanged over the years.

The new section on ultrasound biomicroscopy includes common and rare conditions which involve the anterior segment with corresponding photographs where possible.

Practical issues as to when to perform the test in a given condition, what to look for and the implications on treatment have been dealt with in a brief fashion.

This atlas aims to educate the novice and at the same time refresh the knowledge of the qualified ophthalmologist in one of the segments in the always fascinating field of ophthalmic imaging - ultrasonography.
