    2. Systems and methods for bidirectional functional optical coherence tomography

      Systems and methods for bidirectional functional optical coherence tomography
      Methods for determining improving quantitative and qualitative motion contrast information collected with optical coherence tomography (OCT) data are presented. In one embodiment, flow within a cross-sectional area of a sample is calculated independent of the Doppler and en face angles using a bidirectional OCT system. In another embodiment, motion contrast images are improved by averaging motion contrast information collected from a bidirectional OCT system.

    5. Segmentation of microcystic macular edema in Cirrus OCT scans with an exploratory longitudinal study

      Segmentation of microcystic macular edema in Cirrus OCT scans with an exploratory longitudinal study
      Microcystic macular edema (MME) is a term used to describe pseudocystic spaces in the inner nuclear layer (INL) of the human retina. It has been noted in multiple sclerosis (MS) as well as a variety of other diseases. The processes that lead to MME formation and their change over time have yet to be explained sufficiently. The low rate at which MME occurs within such diverse patient groups makes the ...

      The Different Characteristics of Cirrus Optical Coherence Tomography between Superior Segmental Optic Hypoplasia and Normal Tension Glaucoma with Superior Retinal Nerve Fiber Defect
      Purpose. To evaluate the different characteristics in superior segmental optic hypoplasia (SSOH) and normal tension glaucoma (NTG)with superior retinal nerve fiber layer (RNFL) defect (NTG-SRD) compared to normal control using cirrus optical coherence tomography (OCT). Methods. SSOH eyes and NTG-SRD eyes were reviewed. The peripapillary RNFL (pRNFL) and ganglion cell inner plexiform layer (GCIPL) of the two groups were compared to age-matched normal controls using cirrus OCT. Results. Included ...

    9. Systems and methods for efficiently obtaining measurements of the human eye using tracking

      Systems and methods for efficiently obtaining measurements of the human eye using tracking
      Systems and methods for efficiently obtaining optical coherence tomography (OCT) measurement data with reduced effects of motion are presented. One embodiment involves determining the amount of motion present during the collection of an OCT data set based on images of the eye collected at the same time as the OCT data, and recollecting select portions of the OCT data set when the amount of eye motion is determined to exceed ...

    10. Repeatability of tear meniscus evaluation using spectral-domain Cirrus® HD-OCT and time-domain Visante® OCT

      Repeatability of tear meniscus evaluation using spectral-domain Cirrus® HD-OCT and time-domain Visante® OCT
      Purpose To investigate the intra-rater, inter-rater and inter-device repeatability of a spectral-domain OCT (Cirrus) and a time-domain OCT (Visante) for tear meniscus height (TMH) and area (TMA) measurements. Methods 20 participants with no known eye disease were recruited. Both eyes of participants were imaged with both OCTs under the similar conditions. The inferior tear meniscus was imaged at 6 oclock position whereas the superior meniscus was imaged at 12 oclock ...
