    3. Imaging the anterior eye with dynamic-focus swept-source optical coherence tomography.

      Imaging the anterior eye with dynamic-focus swept-source optical coherence tomography.
      A custom-built dynamic-focus swept-source optical coherence tomography (SS-OCT) system with a central wavelength of 1310 nm was used to image the anterior eye from the cornea to the lens. An electrically tunable lens was utilized to dynamically control the positions of focusing planes over the imaging range of 10 mm. The B-scan images were acquired consecutively at the same position but with different focus settings. The B-scan images were then ...

      Effect of Signal Intensity on Measurement of Ganglion Cell Complex and Retinal Nerve Fiber Layer Scans in Fourier-Domain Optical Coherence Tomography
      Purpose : We determined the effect of Fourier-domain optical coherence tomography (OCT) signal strength index (SSI) and cropping on retinal nerve fiber layer (RNFL) and macular ganglion cell complex (GCC) scan repeatability and measurement thickness. Methods : Eyes were enrolled in the longitudinal Advanced Imaging for Glaucoma Study. At each visit, three repeat scans from the optic nerve head and macular protocols were obtained. Each measurement was associated with an SSI value ...

    10. Optimization of the split-spectrum amplitude-decorrelation angiography algorithm on a spectral optical coherence tomography system

      Optimization of the split-spectrum amplitude-decorrelation angiography algorithm on a spectral optical coherence tomography system
      The split-spectrum amplitude-decorrelation angiography algorithm was optimized on a spectral optical coherence tomography system using a flow phantom. The number of times the spectrum was split and the bandwidth of each split were adjusted to maximize the flow phantom decorrelation signal-to-noise ratio. The improvement in flow detection was then demonstrated with en face retinal angiograms. The optimized algorithm increased the detectable retinal microvascular flow and decreased the variability of the ...

      Optical Coherence Tomography Glaucoma Detection Based On Retinal Vessel Relief Height
      Systems and techniques for detecting glaucoma in a subject based on retinal vessel relief height obtained from optical coherence tomography (OCT) image data are disclosed. In one example approach, a retinal vessel relief height relative to a retinal plane may be calculated from OCT image data and the presence or absence of a glaucoma condition may be determined based on the retinal vessel relief height.

  2. About David Huang

    David Huang

    David Huang joined the Oregon Health & Science University (OHSU) Casey Eye Institute in 2010 as a Professor of Ophthalmology. Dr. Huang earned the MD degree from Harvard University and a PhD in Medical Engineering and Medical Physics from Massachusetts Institute of Technology. He received ophthalmology residency training at USC and fellowship training in cornea, external disease and refractive surgery at Emory University School of Medicine. Before joining the OHSU faculty, Dr. Huang was on the staff of the Cole Eye Institute of the Cleveland Clinic and later on the faculty of Doheny Eye Institute of University of Southern California. Dr. Huang has been named one of best doctors in America by his peers (www.bestdoctors.com) and among the top LASIK surgeons by www.trustedlasiksurgeons.com based on research experience and premier patient care. Dr. Huang is known for his innovations in applying laser and optical technology to eye diseases. He is a co-inventor of optical coherence tomography (OCT), an imaging technology that has been applied to the measurement of eye structures with unprecedented precision. He continues his research in applying OCT to corneal and cataract surgery, glaucoma and retinal diseases

    1. OCT is a big saver of healthcare dollars – the guidance of anti-vascular endothelial growth factor therapy in age-related macular degeneration alone saves billions of dollars per year by avoiding unnecessary injections.

    2. OCT is the most commonly used eye imaging test in the management of the leading causes of blindness today: macular degeneration, diabetic retinopathy and glaucoma. I am proud to be a key contributor to the technology that is preserving vision for people around the world.
      In OHSU Casey Eye Institute Inventor Dr. David Huang Earns International Award for Advances in Eye Imaging
    3. Seeing the blood flow in many layers of the retina is incredibly important because the most important causes of blindness in the world are due to abnormal blood circulation.

    4. There are a few circumstances where mapping the posterior surface is also useful, for example, in post-LASIK cataract surgery intraocular lens calculations, where measuring the anterior surface alone is not sufficient to really accurately measure the net corneal power.
      In Versatile corneal, anterior segment imaging technologies improve accuracy
    5. Confocal microscopy of the cornea has been around for a long time but it still doesn’t have a lot of specificity in looking at microorganisms...Some sort of in vivo staining or fluorescence that allows us to really distinguish infections or microorganisms with confocal imaging would be great
      In Versatile corneal, anterior segment imaging technologies improve accuracy
    6. OCT has higher resolution than any of the anterior segment modalities....I think eventually any function that a topography, ultrasound or slit scanning can do, OCT can do better.

    9. People with poor blood flow don't respond well to some of the laser treatments used for retinopathy, and they are at a higher risk for proliferative retinopathy.
