    2. Handheld forward-imaging needle endoscope for ophthalmic optical coherence tomography inspection

      Shuo Han, Marinko V. Sarunic, Jigang Wu et al. We report the narrowest to-date (21 gauge, 820-[mu]m-diam) handheld forward-imaging optical coherence tomography (OCT) needle endoscope and demonstrate its feasibility for ophthalmic OCT inspection. The probe design is based on paired-angle-rotation scanning (PARS), which enables a linear B-scan pat ... [J. Biomed. Opt. 13, 020505 (2008)] published Mon Apr 21, 2008.

    3. Method and apparatus for measuring a retinal sublayer characteristic

      Methods and systems are provided for measuring a retinal sublayer characteristic of an eye. A plurality of axial scans are performed over an area of the retina of the eye. Reflections are measured during the axial scans to determine a plurality of sets of reflection intensity values. A given set of reflection intensity values is associated with one of the plurality of axial scans. A progressive refinement boundary detection algorithm ...

    4. 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.

    6. In vivo retinal blood flow measurement by Fourier domain Doppler optical coherence tomography

      The measurement of ocular blood flow is important in studying the pathophysiology and treatment of several leading causes of blindness. We present a method for in vivo human retinal flow measurement using Fourier domain optical coherence tomography. A double circular scanning pattern was used to sca ... [Proc. SPIE Int. Soc. Opt. Eng. 6847, 68470G (2008)] published Mon Feb 18, 2008.

    7. In vivo imaging of raptor retina with ultra high resolution spectral domain optical coherence tomography

      Among birds, raptors are well known for their exceptional eyesight, which is partly due to the unique structure of their retina. Because the raptor retina is the most advanced of any animal species, in vivo examination of its structure would be remarkable. Furthermore, a noticeable percentage of traumatic ocular injuries are identified in birds of prey presented to rehabilitation facilities. Injuries affecting the posterior segment have been considered as a ...

    8. Still evolving, OCT technology has revolutionized diagnostics

      Still evolving, OCT technology has revolutionized diagnostics
      Since the early 1990s, optical coherence tomography has revolutionized the way retinal and glaucoma surgeons approach diagnostics in their practices, and it continues to show promise for additional applications. When the technology for optical coherence tomography (OCT) was first developed in 1991, surgeons were impressed by the precise imaging created by this modality but questioned if it would become clinically indispensable. Now, many cannot imagine their practices without it. “At ...

    10. Changes in anterior segment morphology in response to illumination and after laser iridotomy in Asian eyes: an anterior segment OCT study

      Aim: Using the anterior segment optical coherence tomography (AS-OCT) to quantify changes in anterior segment morphology going from light to dark and following laser iridotomy (LI). Methods: Prospective observational study. 17 consecutive subjects without peripheral anterior synechiae undergoing LI were evaluated using gonioscopy and AS-OCT. Angle configuration including angle opening distance (AOD) at 500 microns anterior to the scleral spur, AOD500, trabecular-iris space area up to 750 microns from the ...
