    1. OCT in the Management of Macular Degeneration - Ophthalmology Education Lab

      OCT in the Management of Macular Degeneration - Ophthalmology Education Lab

      Advances in retinal pharmacology have significantly improved outcomes for patients with a range of chronic retinal conditions, including age-related macular degeneration, macular edema, retinal vascular disorders and diseases of the vitreomacular interface. Maximizing the efficacy of available treatments requires the appropriate use of optical coherence tomography (OCT) to diagnose these conditions and to monitor the efficacy of treatment. In this webinar series, leading clinicians and researchers will discuss the role of OCT in detecting structural changes associated with a range of retinal diseases and provide clinical pearls on using tools such as thickness maps, automated change analysis and angiography in ...

      Effect of Contact Lens on Optical Coherence Tomography Imaging of Rodent Retina

      Visibility of optical coherence tomography (OCT) images can be severely degraded by speckle noise. A computationally efficient despeckling approach that strongly reduces the speckle noise is reported. It is based on discrete wavelet transform (DWT), but eliminates the conventional process of threshold estimation. By decomposing an image into different levels, a set of sub-band images are generated, where speckle noise is additive. These sub-band images can be compounded to suppress the additive speckle noise, as DWT coefficients resulting from speckle noise tend to be approximately decorrelated. The final despeckled image is reconstructed by taking the inverse wavelet transform of the ...

      Comparison of Dresen Area Detected by Spectral Domain Optical Coherence Tomography and Color Fundus Imaging

      Purpose: To compare the measurements of drusen area from manual segmentation of color fundus photographs with those generated by an automated algorithm designed to detect elevations of the retinal pigment epithelium (RPE) on spectral domain optical coherence tomography (SDOCT) images. Methods: Fifty eyes with drusen secondary to non-exudative age-related macular degeneration (AMD) were enrolled. All eyes were imaged with the Cirrus HD-OCT instrument (Carl Zeiss Meditec, Dublin, CA) using a 200x200 A-scan raster pattern covering a 6mm X 6mm area centered on the fovea. Digital color fundus images were taken on the same day. Drusen were traced manually on the ...

    6. Visible light optical coherence tomography for in vivo imaging the spectral contrasts of the retinal nerve fiber layer

      Visible light optical coherence tomography for in vivo imaging the spectral contrasts of the retinal nerve fiber layer

      The ultimate goal of the study is to provide an imaging tool to detect the earliest signs of glaucoma before clinically visible damage occurs to the retinal nerve fiber layer (RNFL). Studies have shown that the optical reflectance of the damaged RNFL at short wavelength ( reduced much more than that at long wavelength, which provides spectral contrasts for imaging the earliest damage to the RNFL. To image the spectral contrasts we built a dual-band spectral-domain optical coherence tomography (SD-OCT) with centered wavelength of 415nm (VIS) and 808nm (NIR), respectively. The light at the two bands was provided by the fundamental ...

    7. Dual-band spectral-domain optical coherence tomography for in vivo imaging the spectral contrasts of the retinal nerve fiber layer

      Dual-band spectral-domain optical coherence tomography for in vivo imaging the spectral contrasts of the retinal nerve fiber layer

      The ultimate goal of the study is to provide an imaging tool to detect the earliest signs of glaucoma before clinically visible damage occurs to the retinal nerve fiber layer (RNFL). Studies have shown that the optical reflectance of the damaged RNFL at short wavelength (<560nm) is reduced much more than that at long wavelength, which provides spectral contrast for imaging the earliest damage to the RNFL. To image the spectral contrast we built a dual-band spectral-domain optical coherence tomography (SD-OCT) centered at 808nm (NIR) and 415nm (VIS). The light at the two bands was provided by the fundamental and frequency-doubled outputs of a broadband Ti:Sapphire laser. The depth resolution of the NIR and VIS OCT systems are 4.7µm and 12.2µm in the air, respectively. The system was applied to imaging the rat retina in vivo. Significantly different appearances between the OCT cross sectional images at the two bands were observed. The ratio of the light reflected from the RNFL over that reflected from the entire retina at the two bands were quantitatively compared. The experimental results showed that the dual-band OCT system is feasible for imaging the spectral contrasts of the RNFL.

    12. Topographic Differences in the Age-related Changes in the Retinal Nerve Fiber Layer of Normal Eyes Measured by Stratus Optical Coherence Tomography

      Topographic Differences in the Age-related Changes in the Retinal Nerve Fiber Layer of Normal Eyes Measured by Stratus Optical Coherence Tomography
      Purpose: To determine whether there are regional differences in the age-related changes in peripapillary retinal nerve fiber layer (RNFL) thickness as measured by time-domain optical coherence tomography (OCT). Methods: Fast peripapillary RNFL scans obtained with the Stratus time-domain OCT with nominal diameter of 3.46-mm centered on the optic disc were carried out on 425 normal participants over a wide age range. One eye was randomly selected for scanning or analysis. Average RNFL-, clock hour-, and quadrant-specific rates of RNFL thickness change were calculated and compared. Results: The 425 study participants ranged in age from 18 to 85 years with ...
