Description 

B scan ultrasonography is the most commonly used modality for the assessment of posterior segment pathologies.1–3 On placing the probe along the lateral longitudinal axis, the nasal aspect of the retina, ciliary body, the lens in its entirety, iris, angle and peripheral cornea can be appreciated easily. Using this technique, the anatomy of the lens can be studied in terms of its width along the horizontal and anteroposterior extent; similarly, by placing the probe along the inferior longitudinal axis, the vertical width of the lens can be defined, along with the anteroposterior thickness. This technique helps in the assessment of lens in its entirety, from the anterior capsule to the posterior capsule. Herein few pathologies of the lens and its capsule are illustrated using B scan ultrasound (Sonomed, New York, USA).
