ZEISS AngioPlex - Prima Installazione in Italia

L'Angiografia OCT senza mezzo di contrasto(dynless) è un'innovativa tecnologia di imaging che permette di visualizzare in modo eccellente la vascolarizzazione corioretinica. Durante un comune esame oct si può osservare la rete vascolare superficiale e profonda ed arrivare alla diagnosi prima di qualsiasi altro esame strumentale. Questa tecnologia si sta sviluppando a grandi passi sostituendo in gran parte l'esame fluoroangiografico che necessita di mezzo di contrasto. Le immagini che l'angiografia oct dynless permette, offrono la possibilità di fare diagnosi precoce nelle maculopatie retiniche e nel glaucoma, anticipando l'instaurarsi del danno strutturale e permettendo di intervenire con la terapia più adeguata in modo mirato. Angioplex Zeiss è il primo AngioOCT ad aver avuto l'approvazione dalla FDA in USA. Principi tecnologici e imaging degli Angio-OCT sito ufficiale zeiss
