    摘要: A method for detecting glaucoma in a subject based on spatial frequency analysis of the inner limiting membrane (ILM) as obtained from optical coherence tomography (OCT) image data is disclosed. Based on the spatial frequency content of the analyzed ILM profile, a quantity called the Retinal surface contour variability (RSCV) is calculated and the presence or absence of a glaucoma condition is determined based on the RSCV magnitude.

    摘要: Methods of performing en face Doppler total retinal blood flow measurement are disclosed. The methods involve obtaining a set of structural OCT scans; calculating a noise-reduced set of Doppler phase shift images by dividing the full spectrum OCT fringe data into a set of narrower filtered frequency bands for phase shift calculation; removing bulk motion along a depth direction; detecting retinal vessels in the set of images; applying a phase unwrapping algorithm to the images; classifying the vessels as veins and arteries; and calculating total retinal blood flow based on that classification.

    摘要: A heat-dissipating structure for LED lamp has a lamp cover, and a power conversion device and a ceramic substrate mounted inside the lamp cover. The lamp cover has multiple heat-dissipating holes and multiple mounting ears. Each mounting ear is formed on an edge of one of the heat-dissipating holes and is bent inwardly with the heat-dissipating hole uncovered. The ceramic substrate is mounted on the mounting ears. The ceramic substrate has multiple LEDs mounted thereon, absorbs heat generated when the LEDs emit light and conducts the heat to the lamp cover through the mounting ears. The heat generated when the LEDs are lit and the power conversion converts a mains power is transferred to a heat convection space between the ceramic substrate and the lamp cover, and is further dissipated to an ambient environment, thereby achieving fast heat dissipation and a light LED lamp without additional heat sink thereon.

    摘要: Methods for analyzing retinal tomography maps to detect patterns of optic nerve diseases such as glaucoma, optic neuritis, anterior ischemic optic neuropathy are disclosed in this invention. The areas of mapping include the macula centered on the fovea, and the region centered on the optic nerve head. The retinal layers that are analyzed include the nerve fiber, ganglion cell, inner plexiform and inner nuclear layers and their combinations. The overall retinal thickness can also be analyzed. Pattern analysis are applied to the maps to create single parameter for diagnosis and progression analysis of glaucoma and optic neuropathy.
