Application of spectral domain-OCT before and after vitreoretinal surgery

Spectral domain OCT (SD-OCT) has faster scanning speed and higher resolution than traditional time-domain OCT.It can distinguish the subtle lesions in the retina especially outer retina.It may provide a local configuration details before vitreoretinal surgery and help to raise the plan of the operation; after surgery,following up with SD-OCT is helpful to determine the visual outcome by observation of outer retina. Key words: spectral domain OCT;  vitreoretinal surgery
