      Handheld optical coherence tomography removes barriers to imaging the eyes of young children
      Optical coherence tomography (OCT) has revolutionised the clinical practice of ophthalmology. Its use has become widespread across most major branches of ophthalmology, including medical retina, surgical retina, glaucoma, neuro-ophthalmology, uveitis, cornea, anterior segment and refractive surgery, primary care ophthalmology and ocular oncology. However, conventional table-mounted OCT devices are not designed for infants and young children, who have previously been deprived of this technology and its many clinical benefits. Furthermore, many ...

      Explore TVST Journal Ophthalmology
      OCT Assisted Quantification of Vitreous Inflammation in Uveitis
      Purpose: Vitreous haze (VH) is a key marker of inflammation in uveitis but limited by its subjectivity. Optical coherence tomography (OCT) has potential as an objective, noninvasive method for quantifying VH. We test the hypotheses that OCT can reliably quantify VH and the measurement is associated with slit-lamp based grading of VH. Methods: In this prospective study, participants underwent three repeated OCT macular scans to evaluate the within-eye reliability of ...

      Macular thickness varies with age-related macular degeneration genetic risk variants in the UK Biobank cohort
      To evaluate the influence AMD risk genomic variants have on macular thickness in the normal population. UK Biobank participants with no significant ocular history were included using the UK Biobank Resource (project 2112). Spectral-domain optical coherence tomography (SD-OCT) images were taken and segmented to define retinal layers. The influence of AMD risk single-nucleotide polymorphisms (SNP) on retinal layer thickness was analysed. AMD risk associated SNPs were strongly associated with outer-retinal ...

      Purpose: To investigate modeling of the focal visual field (VF) loss by combining structural measurements and vascular measurements in eyes with early primary open-angle glaucoma (POAG). Methods: In this cross-sectional study, subjects with early glaucoma (VF mean deviation, -6 dB) underwent optical coherence tomography (OCT) imaging, optical coherence tomography angiography (OCTA) imaging, and Humphrey 24-2 VF tests. Capillary perfusion densities (CPDs) were calculated after the removal of large vessels in ...

      Importance: Although the diagnosis of vitreoretinal lymphoma (VRL) can be challenging, early detection is critical for visual prognosis. Objective: To analyze the spectrum of optical coherence tomography (OCT) findings in patients with biopsy-proven VRL and correlate these features with clinical parameters. Design: Retrospective cross-sectional study SETTING: Multicenter chart review from 13 retina, uveitis and ocular oncology clinics worldwide over an 11-year period (2008-2019).

      Fraunhofer Technology Revolutionises 3D Printing of Prosthetic Eyes
      Prosthetic eye replacements will be manufactured by 3D printers in the future. Fraunhofer IGD has developed a number of technologies that supersedes the current and entirely manual production of individual prostheses. Fraunhofer's Cuttlefish:Eye software utilises a 3D scan of the eye socket and a colour-calibrated photo of the healthy eye to create the prosthetic eye's 3D model. Fraunhofer's Cuttlefish 3D printing driver is used to print ...

      Clinically relevant deep learning for detection and quantification of geographic atrophy from optical coherence tomography: a model development and external validation study
      Background: Geographic atrophy is a major vision-threatening manifestation of age-related macular degeneration, one of the leading causes of blindness globally. Geographic atrophy has no proven treatment or method for easy detection. Rapid, reliable, and objective detection and quantification of geographic atrophy from optical coherence tomography (OCT) retinal scans is necessary for disease monitoring, prognostic research, and to serve as clinical endpoints for therapy development. To this end, we aimed to ...

      Dependency of hydration and growth conditions on the mechanical properties of oral biofilms
      Within the oral cavity, dental biofilms experience dynamic environments, in part due to changes in dietary content, frequency of intake and health conditions. This can impact bacterial diversity and morpho-mechanical properties. While phenotypic properties of oral biofilms are closely related to their composition, these can readily change according to dynamic variations in the growth environment and nutrient availability. Understanding the interlink between phenotypic properties, variable growth conditions, and community characterization ...
