What does standardized Echography combine?

Standardized Echography involves the combination of A-scan and contact B-scan modalities. A-scan ultrasound provides precise axial measurements of the eye, such as axial length, and is fundamental for calculating intraocular lens power prior to cataract surgery. On the other hand, contact B-scan ultrasound offers a two-dimensional view of the structures within the eye, making it useful for evaluating complex diseases and conditions like retinal detachment or tumors.

By integrating both A-scan and contact B-scan techniques, standardized echography delivers comprehensive information about eye anatomy and measurements, which is essential for accurate diagnosis and treatment planning in ophthalmology. This combination allows clinicians to not only measure specific dimensions but also visualize the anatomical structures, leading to more informed clinical decisions.
