摘要： The present invention generally provides methods and systems for performing in vivo flow cytometry by using blood vessels as flow chambers through which flowing cells can be monitored in a live subject in vivo without the need for withdrawing a blood sample. In some embodiments, one or more blood vessels are illuminated with radiation so as to cause a multi-photon excitation of an exogenous fluorophore that was previously introduced into the subject to label one or more cell types of interest. In some other embodiments, rather than utilizing an exogenous fluorophore, endogenous (intrinsic) cellular fluorescence can be employed for in vivo flow cytometry. The emission of fluorescence radiation from such fluorophores in response to the excitation can be detected and analyzed to obtain information regarding a cell type of interest.

摘要： The present invention provides devices and methods for applying radiation to the retina of a patient. In one embodiment, an apparatus includes a radiation source for generating a radiation beam suitable for absorption by retinal pigment epithelial cells. One or more optical components are included to direct the beam onto the retina. A scanner is optically coupled to the radiation source to control movement of the beam in two dimensions to allow a scan over the retina. A controller applies control signals to the scanner to adjust beam movement to illuminate a plurality of retinal locations in a temporal sequence according to a predefined pattern. The device can be operated in one mode to effect selective targeting of retinal pigment epithelial cells, or in another mode to effect thermal photocoagulation of the retina.
