Conventional imaging modalities are unable to depict the early degeneration of articular cartilage in osteoarthritis, especially in small joints. Optical coherence tomography has previously been used successfully in high-resolution imaging of cartilage tissue. This pilot cadaver study demonstrates the use of intra-articular optical coherence tomography in imaging of articular cartilage of the f...

OBJECTIVE To use optical coherence tomography to assess the in vivo pathologic findings associated with incomplete visual recovery in patients who have undergone anatomically successful surgery to treat proliferative vitreoretinopathy. METHODS Eligible patients were recruited in vitreoretinal outpatient clinics between April 1, 2002, and July 31, 2003. Patients were included who had undergone...

The principle and the applications of a recently proposed unconventional holography technique, called coherence holography, and a related technique for dispersion-free 3-D coherence imaging based on a spatial frequency comb will be reviewed. ©2007 Optical Society of America OCIS codes: (090.0090) Holography; (030.1640) Coherence; (100.3010) Image reconstruction techniques; (110.4500) Optical co...

We report an experimental demonstration of optical coherence tomography for transmissive objects utilizing second-order correlation ghost imaging with thermal light. To evaluate the longitudinal resolution of our system, the concept of the imaging longitudinal coherence length is introduced, which is more accurate for judging the image quality of ghost imaging with unequal optical paths than th...

this article reviews clinically relevant data regarding traumatic maculopathy (tm), frequently observed in clinical practice, especially due to sport or traffic accident injuries. it is characterized by transient gray-whitish retinal coloration and reduction of visual acuity (va) with closed, blunt object globe trauma of their prior. it may be limited to the posterior pole (berlin’s edema), o...
