    2. Reliability and validity of Cirrus and Spectralis optical coherence tomography for detecting retinal atrophy in Alzheimer’s disease

      Reliability and validity of Cirrus and Spectralis optical coherence tomography for detecting retinal atrophy in Alzheimer’s disease

      Background To evaluate and compare the ability of two Fourier-domain optical coherence tomography (OCT) devices to detect retinal and retinal nerve fibre layer (RNFL) atrophy in patients with Alzheimer’s disease (AD) compared with healthy subjects; to test the intra-session reliability of two OCT devices in AD patients and healthy subjects. Methods AD patients (n = 75) and age-matched healthy subjects (n = 75) underwent three Macular Cube 200 × 200 protocols using the Cirrus and Spectralis OCT devices and three 360° circular scans centred on the optic disc using the Cirrus OCT device, the classic glaucoma application, and the new Nsite Axonal ...

    4. Pathology detection rate of spectral domain optical coherence tomography devices

      Pathology detection rate of spectral domain optical coherence tomography devices

      Background Spectral domain optical coherence tomography (SDOCT) allows for higher resolution scans and higher scanning speeds compared to time domain OCT (TDOCT). The purpose of this study is to compare the pathology detection rates of various SDOCT devices to the Stratus TDOCT. Methods Patients with neovascular age-related macular degeneration were imaged on the Stratus and one of four SDOCT devices. The images were then analysed in a masked manner evaluating for the presence of epiretinal membrane (ERM), pigment epithelial detachment (PED) and subretinal fluid (SRF). After determining that low scan density with one of the devices was likely the cause ...

    5. Spectral- and time-domain optical coherence tomography measurements of macular thickness in young myopic eyes

      Spectral- and time-domain optical coherence tomography measurements of macular thickness in young myopic eyes

      Purpose: To evaluate the variation in macular retinal thickness and volume in young Chinese myopic patients using time-domain optical coherence tomography (Stratus TD-OCT) and spectral-domain optical coherence tomography (Cirrus HD-OCT). Methods Ninety-two eyes of 92 myopic subjects were recruited in this study. Based upon spherical equivalence (SE), subjects were divided into two groups: the low to moderate myopia group (-0.5 D <= SE < -6.0 D), and the high myopia group (SE >= -6.0 D). Stratus TD-OCT and Cirrus HD-OCT were used to compare macular retinal thickness and volume between the two groups. Bland-Altman analysis and Pearson correlation were used ...

    6. Method For Measuring An Eye

      Method For Measuring An Eye

      A method for measuring the axial length of an eye using optical coherence tomography, during which a plurality of A-scans of the OCT measurement are combined to an axial length, taking into account the alignment with which they were obtained, and taking into account the topography of the cornea. The distance of the front of the cornea from the retina is determined using OCT while measuring or controlling the alignment of the measuring device to the eye in that the topography of the front of the cornea is measured or made available. The calculation of an axial length from an ...

    7. Spectral-domain optical coherence tomography evaluation of postoperative cystoid macular oedema following phacoemulsification with intraoperative complication

      Spectral-domain optical coherence tomography evaluation of postoperative cystoid macular oedema following phacoemulsification with intraoperative complication

      Background To report the rate of cystoid macular oedema (CMO) as detected by spectral-domain optical coherence tomography (SD-OCT) after intraoperative complication during phacoemulsification. The secondary objectives include comparing mean macular thickness and best-corrected visual acuity (BCVA) between those who developed postoperative CMO against those who did not. Methods This is a prospective cohort study conducted in a tertiary hospital between July 2009 and June 2010. Serial SD-OCT and BCVA were performed at baseline, 1 week, 6 weeks and 16 weeks postoperatively. Results Single eyes from 47 subjects were analyzed; of these 16 (34%) eyes developed CMO. In the CMO group ...
