简要总结
The Intalight Dream OCT is the first combo anterior plus posterior device to perform both OCT and OCT-A at depth of 16mm. This is especially useful in patient who are very nearsighted as it allows us to image all in one frame. The intention of this study is to see how the images differ on the same patients when compared to the Cirrus OCT and to test for the repeatability of the images on a single day.
