          Cyctoid macula edema (blue arrow). High
        
        
          accumulation of fluid in the area of the central fovea organized in
        
        
          cystic formation. The yellow arrow show the vitreous which has been
        
        
          detached. In comparison to the normal appearance (green arrow).

          An OCT examination can reveal the smallest changes or deterioration
        
        
          in the structure of the retina. It is totally necessary in the initial
        
        
          evaluation of macular edema and the monitoring of the therapeutic
        
        
          outcome.
        
        
          The first generation were Time Domain OCT (TD OCT) machines,
        
        
          with resolution of 10 (ten) μm (microns - millionth of a meter). The
        
        
          next evolution were the Spectral Domain OCT (SD OCT), improving
        
        
          the resolution to 1-3μmwith 40000 A Scans per second, accelerating
        
        
          examination speed faster and adding a 3-dimentional capability, in
        
        
          the mapping of  the retina.

            Athens Eye Hospital
          
        
        
          we have the latest generation Swept Source
        
        
          OCT, with the capability of 100000 A-scans per second and a greater
        
        
          penetrating capability for better control.
