WebImages of the mouse eye taken with a 1310 nm OCT. A) A view of the cornea in “radial” mode for alignment of the first Purkinje image in the center of the pupil. B) A typical image of the mouse eye which takes advantage of the “mirror artifact” to superimpose the anterior and posterior portions of the eye in the same imaging frame. WebPolarization-sensitive optical coherence tomography (PS-OCT) enables noninvasive, high-resolution imaging of tissue polarization properties. In the anterior segments of human eyes, PS-OCT allows the visualization of birefringent and depolarizing structures. We present the use of PS-OCT for imaging the murine anterior eye.
