    2. 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 ...

    3. 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 ...

    4. 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 ...

    5. 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 ...

    8. SS OCT interferometry for measuring a sample

      SS OCT interferometry for measuring a sample

      An SS OCT interferometry device for measuring a sample, in particular from an eye. The device interferometrically generates a measuring signal and from the signal a depth-resolved contrast signal of the sample by spectral tuning of the central wavelength of the measurement radiation of a measuring signal, and has a control unit for this purpose. The device includes a sample motion detector, which provides a motion signal indicating movement of or in the sample, the control unit uses the motion signal to correct the measuring signal with respect to measuring errors that are caused by a movement of or in ...

    11. Anterior segment optical coherence tomography for demonstrating posterior capsular rent in posterior polar cataract

      Anterior segment optical coherence tomography for demonstrating posterior capsular rent in posterior polar cataract

      Aims/purpose: To report the preoperative use of anterior segment optical coherence tomography (AS-OCT) for the determination of pre-existing posterior capsule defect in patients with posterior polar cataract. Methods: Three patients presented with posterior polar cataract and were evaluated preoperatively using AS-OCT, revealing in one patient intact posterior capsule and in the other two a pre-existing posterior capsule defect not detectable by slit-lamp evaluation. All patients underwent phacoemulsification and intraocular lens implantation. Results: Intraoperatively, AS-OCT findings were confirmed after cataract surgery in all patients. No intra- or late postoperative complications were noted. Conclusion: AS-OCT could be an additional useful imaging ...

    12. Sensitivity of Fluid Detection in Patients With Neovascular AMD Using Spectral Domain Optical Coherence Tomography High-Definition Line Scans

      Sensitivity of Fluid Detection in Patients With Neovascular AMD Using Spectral Domain Optical Coherence Tomography High-Definition Line Scans

      Purpose: To determine the sensitivity of the Cirrus high-definition (HD) 5-line raster scans for detecting retinal fluid in neovascular age-related macular degeneration when using the spectral domain optical coherence tomography macular cubes as a gold standard. Methods: Patients were retrospectively identified from their initial follow-up visit after being newly diagnosed with neovascular age-related macular degeneration in at least one eye. Patients were imaged with Cirrus spectral domain optical coherence tomography using the 512 x 128 macular cube scan and HD 5-line raster scan settings. Patients with other diseases that cause subretinal or intraretinal fluid, or who had an epiretinal membrane ...
