  • Abstract
  • Look Inside

A new procedure of multidirectional A-mode ultrasonography is described for the better de-tection and localization of intravitreal and fun-dus lesions. The beam is directed at the poste-rior pole along 8 meridians of the eye at 3 angles (30°, 60°and 90°) each from the optical axis. With the addition of measurement along the axis, a total of 25 echograms are thus obta-ined. The present procedure facilitates a more concentrated coverage of the posterior vitreous and the fundus area behind the equator. A more exact description and consequently a more precise localization of echographic pathological lesion is made also possible.
