Actual resolution of the OCT. (a) In the case of 150 nm spectral width, axial resolution reached up to 2.84 μm in the air. This corresponds to the resolution of 2.03 μm in retina. (b) In the case of 200 nm spectral width, axial resolution reached up to 1.79 μm in the air. This corresponds to the resolution of 1.28 μm in retina.
3D image synthesized from the raster scanning images of AMD. Neovascular vessels penetrate through the Bruch membrane and a neovascular network has been protruded upward. We showed the position of the Bruch membrane with an arrow.
The video motion images of an optic disc visualize the vessel arrangement and show that the diameter of a vessel changes corresponding to the pulsation (see the vessel indicated by an arrow).
The tomography image of an optic disc of a glaucoma patient shows clearly the fine structure of an optic disc. Arrow A indicates an optic nerve fiber intrusion part, arrow B indicates a non-structure organization on the OD plane, and arrow C indicates a lamina cribrosa.
A 3D optic disc image was synthesized from the raster scanning images. We can clearly see the structure of a lamina cribrosa, vessels, and a disc wall from any angle. The lamina dot sign at a lamina cribrosa is shown with an arrow in the picture.
A 3D image of a lamina cribrosa itself was selectively constructed using a 3D optic disc image. We can easily recognize this lamina cribrosa is a mesh type one.
