    2. Measurement of granule layer thickness in a spouted bed coating process via optical coherence tomography

      Measurement of granule layer thickness in a spouted bed coating process via optical coherence tomography
      In this work a recently developed in-line measurement technique for monitoring of coating thickness was applied to a spray-coating process in a three-dimensional prismatic spouted bed. The layer thickness was quantified with an optical coherence tomography (OCT) sensor positioned in front of the observation window of the process chamber. The time-dependent layer thickness was measured directly and in real-time from the OCT images, with no chemometric calibration being needed. To ...

    3. Relationship between Neovascular Density in Swept Source-Optical Coherence Tomography Angiography and Signs of Activity in Exudative Age-Related Macular Degeneration

      Relationship between Neovascular Density in Swept Source-Optical Coherence Tomography Angiography and Signs of Activity in Exudative Age-Related Macular Degeneration
      Purpose . To assess the relationship between signs of activity in exudative neovascular age-related macular degeneration (nAMD) following anti-vascular endothelial growth factor (anti-VEGF) treatment and morphology of choroidal neovascularization (CNV) based on neovascular density as imaged using swept source-optical coherence tomography angiography (SS-OCTA) in a qualitative manner. Methods . A single-cohort retrospective data analysis from one tertiary eye care center. Seventy-seven eyes of 72 patients were included and their charts reviewed which ...

    4. How to Measure Coating Thickness of Tablets: Method Comparison of Optical Coherence Tomography, Near-infrared Spectroscopy and Weight-, Height- and Diameter Gain

      How to Measure Coating Thickness of Tablets: Method Comparison of Optical Coherence Tomography, Near-infrared Spectroscopy and Weight-, Height- and Diameter Gain
      Film coating of pharmaceutical dosage forms, such as tablets and pellets, can be used to tailor the drug release profile. With that regard, a uniform coating thickness of a single tablet (intra-tablet), all tablets (inter-tablet) and subsequent batches (inter-batch) is crucial. We present a method comparison between in-line (optical coherence tomography and near-infrared spectroscopy) and well-established off-line (height-, weight- and diameter-gain) approaches to determining the coating thickness of tablets. We ...

    5. Dynamic intraoperative optical coherence tomography for inverted internal limiting membrane flap technique in large macular hole surgery

      Dynamic intraoperative optical coherence tomography for inverted internal limiting membrane flap technique in large macular hole surgery
      Background/objectives To assess the efficacy of dynamic intraoperative spectral-domain optical coherence tomography (iSD-OCT) imaging for inverted internal limiting membrane (ILM) flap technique (IILMFT) in large macular hole (MH) surgery. Subjects/methods Prospective, non-randomized, observational study was conducted on 8 eyes of 7 patients with large, chronic and recurrent MHs, which were treated by pars plana vitrectomy (PPV) with IILMFT. All patients underwent standard pre- and postoperative examination. The iSD-OCT ...

    6. Influence of optic media of the human eye on the imaging of Argus® II retinal prosthesis with intraoperative spectral-domain optical coherence tomography

      Influence of optic media of the human eye on the imaging of Argus® II retinal prosthesis with intraoperative spectral-domain optical coherence tomography
      Background This study aimed to evaluate the influence of the optic media of the human eye on intraoperative spectral-domain optical coherence tomography (iSD-OCT) of an Argus II retinal prosthesis (AIIRP) during its implantation. Methods One AIIRP was implanted in a human eye with end-stage retinitis pigmentosa and another one in a test eye. Intraoperative imaging was performed using the Rescan 700, a microscope-integrated iSD-OCT system. The feasibility of iSD-OCT imaging ...

    7. Introduction to swept source optical coherence tomography angiography

      Introduction to swept source optical coherence tomography angiography
      Swept source optical coherence tomography (OCT) technology and OCT-angiography (OCT-A) are two recent developments that have the potential to significantly change our understanding of retinal pathology and retinal vascular pathophysiology. In order to correctly use these technologies to their full diagnostic potential, a thorough understanding of the technology as well as its benefits and limitations is essential. The aim of this review article is to provide an introductory understanding of ...

    8. Estimating Retinal Blood Flow Velocities by Optical Coherence Tomography

      Estimating Retinal Blood Flow Velocities by Optical Coherence Tomography
      Importance While optical coherence tomography (OCT) angiography has been considered to evaluate retinal capillary blood flow instead of fluorescein angiography, the reflectance pattern of blood vessels on structural OCT might also provide retinal capillary flow data in the absence of fluorescein angiography. This potential has been insufficiently explored, despite promising data concerning a possible relationship between the reflectance pattern of blood vessels and their perfusion velocity in a laboratory setting ...

    9. Evaluation of intraocular lens position during phacoemulsification using intraoperative spectral-domain optical coherence tomography

      Evaluation of intraocular lens position during phacoemulsification using intraoperative spectral-domain optical coherence tomography
      Purpose To assess the position of intraocular lenses (IOLs) at the end of standard phacoemulsification with intraoperative spectral-domain optical coherence tomography (SD-OCT). Settings Department of Ophthalmology, Rudolf Foundation Hospital, Vienna, Austria. Design Prospective case series. Methods Standard phacoemulsification with IOL implantation was performed. The Rescan 700 SD-OCT system was used for intraoperative imaging. The anterior segment of the eye was scanned using SD-OCT at the end of the surgery. The ...

    10. Assessment of estimated retinal atrophy progression in Stargardt macular dystrophy using spectral-domain optical coherence tomography

      Assessment of estimated retinal atrophy progression in Stargardt macular dystrophy using spectral-domain optical coherence tomography
      Aims To estimate disease progression based on analysis of macular volume measured by spectral-domain optical coherence tomography (SD-OCT) in patients affected by Stargardt macular dystrophy (STGD1) and to evaluate the influence of software errors on these measurements. Methods 58 eyes of 29 STGD1 patients were included. Numbers and types of algorithm errors were recorded and manually corrected. In a subgroup of 36 eyes of 18 patients with at least two ...

    11. In-Line Monitoring of a Pharmaceutical Pan Coating Process by Optical Coherence Tomography

      In-Line Monitoring of a Pharmaceutical Pan Coating Process by Optical Coherence Tomography
      This work demonstrates a new in-line measurement technique for monitoring the coating growth of randomly moving tablets in a pan coating process. In-line quality control is performed by an optical coherence tomography (OCT) sensor allowing nondestructive and contact-free acquisition of cross-section images of film coatings in real time. The coating thickness can be determined directly from these OCT images and no chemometric calibration models are required for quantification. Coating thickness ...
