Resulta clara la relevancia de la ecografía de muy alta frecuencia en el estudio de los glaucomas primitivos de ángulo cerrado. Esta técnica suele ser de utilidad para el diagnóstico en diversos casos de cierre angular secun-dario. Se trata de una técnica de exploración muy rigurosa que requiere formación y práctica.

The importance of very high-frequency ultrasound in the study of primary angle-closure glaucoma is obvious. It often contributes to the diagnosis in several secondary angle-closure situations. It is a very thorough examination technique which requires training and practice.
By Pierre Pégourié & Dominique Satger
UBM, or very high-frequency ultrasound, uses transducers, the frequency of which is higher than 20 MHz, whereas the usual standard in ocular ultrasound uses probes of 10 MHz. Charles Pavlin first described the use of ultrasound for the anterior segment in the early 1990s.

This single centre observational study aims to clarify the differences between single and double eyelid structures in Asian population. UBM images made with Quantel Medical’s Lin50 probe correlate both quantitatively and qualitatively with anatomic structures.
With the availability of advanced forms of imaging such as computed tomography (CT) and magnetic resonance imaging (MRI), does standardized echography (SE) still have a role in the diagnosis of ocular tumors? The answer is yes, this technology is still helpful, and it can reveal the internal structure of lesions better than...

During the 1960's, the signal processing A-Scans, i.E., the way A-Scan achograms are being shaped and are displayed, has been optimized and standardized. This standardization includes a precise and meaningful recording of the Reflectivity of an acoustis surface such as the surface of retina or that of a vitreous membrane...

La anomalía de Axenfeld – Rieger es una enfermedad de herencia autosómico dominante hasta en el 70% de los casos, aunque presenta una variable expresividad, con una considerable heterogenicidad genética sugerida por la gran variedad de anomalías cromosómicas encontradas. Hasta un 60% de los casos han sido caracterizados con los genes PITX2(4q25), FOXC1(6p25) y genes no identificados en el 13q24, 16q24 y cromosoma 11.
