The combination of intravital microscopy and animal models of disease has propelled studies of disease mechanisms and treatments. However, many disorders afflict tissues inaccessible to light microscopy in live subjects. Here we introduce cellular-le

Multiple evanescent white dot syndrome (MEWDS) is a disease of unknown etiology that characteristically occurs in women in the second to fifth decades.1 Ophthalmoscopic examination typically reveals multiple, 100- to 200-μm yellow-white dots deep to

Objective Optical coherence tomography (OCT) has been shown to be a valuable tool in glaucoma assessment. We investigated a new ultrahigh-resolution OCT (UHR-OCT) imaging system in glaucoma patients and compared the findings with those obtained by co

Emission of single quantum-well superluminescent diodes of two types in spectral ranges between 810 and 870 nm and between 860 and 970 nm is combined with the help of an original broadband fibre Y-coupler. Such a light source produces more than 5 mW

Enhanced tissue contrast in developmental biology specimens is demonstrated in vivo using a new type of spectroscopic optical coherence tomography analysis that is insensitive to spectroscopic noise sources. The technique is based on a statistical an
