    1. Methods for diagnosing glaucoma utilizing combinations of FD-OCT measurements from three anatomical regions of the eye

      Methods for diagnosing glaucoma utilizing combinations of FD-OCT measurements from three anatomical regions of the eye
      This invention discloses methods and systems for diagnosing glaucoma by combining diagnostic parameters derived from optical coherence tomography images of three different anatomic regions of the eye, including the macular ganglion cell complex (mGCC), the peripapillary nerve fiber layer (ppNFL), and the optic nerve head (ONH). The combined diagnostic parameters form a reduced set of global parameters, which are then fed to pre-trained machine classifiers as input to arrive at a single diagnostic indicator for glaucoma. Also disclosed are methods for training a machine classifier to be used in methods and systems of this invention.

    2. Measurement of total blood flow in the normal human retina using Doppler Fourier-domain optical coherence tomography

      Aim: To measure total retinal blood flow in normal human eyes using Doppler Fourier-domain optical coherence tomography (FD-OCT). Methods: 10 normal people aged 35 to 69 years were measured for the right eye using Doppler FD-OCT. Double circular scans around the optic nerve heads were used. Four pairs of circular scans that transected all retinal branch vessels were completed in 2 seconds. Total retinal blood flow was obtained by summing the flows in the branch veins. Measurements from the eight scans were averaged. Veins with diameters > 33 µm were taken into account. Results: Total retinal blood flow could be measured ...

    3. Glaucoma diagnosis by mapping macula with Fourier domain optical coherence tomography

      Ou Tan, Ake Lu, Vik Chopra et al. A new image segmentation method was developed to detect macular retinal sub-layers boundary on newly-developed Fourier-Domain Optical Coherence Tomography (FD-OCT) with macular grid scan pattern. The segmentation results were used to create thickness map of macular ganglion cell complex (GCC), which ... [Proc. SPIE Int. Soc. Opt. Eng. 6915, 69153L (2008)] published Mon Mar 17, 2008.
