Publication number: 20180360303Abstract: An exemplary system, method and computer-accessible medium can be provided that can, for example, can be provided so as to receive regarding at least one portion of an ophthalmic sample(s) based on a radiation(s) provided from the sample(s). In addition, it is possible to determine whether an inflammation marker(s) is present in a portion(s) of the sample(s) based on the information. Further, an identification can be performed as to that an abnormality(s) exists in a further anatomical structure based on the determination. The further anatomical structure can be different from the sample(s).Type: ApplicationFiled: May 21, 2018Publication date: December 20, 2018Inventors: Charles P. Lin, Clemens Alt

Patent number: 9289128Abstract: 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.Type: GrantFiled: September 30, 2013Date of Patent: March 22, 2016Assignee: The General Hospital CorporationInventors: Charles P. Lin, Alicia L. Carlson, Clemens Alt, David P. Biss, Costas M. Pitsillides, Chungiang Li

Patent number: 8968280Abstract: Methods and systems for controlling selective targeting of retinal pigment epithelium (RPE) cells within a treatment region of the RPE. The methods include (a) depositing a selected amount of energy on a test region of the RPE; (b) determining an extent to which microcavitation has occurred in the test region; and (c) on the basis of the determination, either depositing the selected amount of energy on the treatment region, or depositing an increased amount of energy on the test region, and repeating steps (b) and (c).Type: GrantFiled: January 22, 2010Date of Patent: March 3, 2015Assignee: The General Hospital CorporationInventors: Charles P.

Patent number: 8366704Abstract: 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.Type: GrantFiled: May 25, 2012Date of Patent: February 5, 2013Assignee: The General Hospital CorporationInventors: Charles P.
