      Detailed Phenotyping and Characterization of Choroidal Morphological and Vascular Features in Young Men with High Myopia Using Spectral-Domain Optical Coherence Tomography

      Purpose To describe detailed morphological and vascular features of the choroid in eyes with high myopia. Design Cross-sectional study. Methods 515 eyes of young men (mean age 21.59±1.15) years) with high myopia (defined as -6.0 D or worse, mean spherical equivalent -8.66±2.00 D) and 88 controls with emmetropia in both eyes underwent choroidal imaging using spectral domain optical coherence tomography with enhanced depth imaging (EDI-OCT). Raw OCT images were loaded on a custom-written application on MATLAB that enabled delineation for detailed morphological and vascular analyses, including the distance of thickest point from the ...

    2. Association of iris surface features with iris parameters assessed by swept-source optical coherence tomography in Asian eyes

      Association of iris surface features with iris parameters assessed by swept-source optical coherence tomography in Asian eyes

      Background/aims To characterise the association of iris surface features (crypts, furrows and colour) with iris volume and curvature assessed by swept-source optical coherence tomography (SSOCT) in Asian eyes. Methods Iris crypts (by number and size) and furrows (by number and circumferential extent) were graded from iris photographs. Iris colour was measured by a customised algorithm written on MATLAB (MathWorks, Natick, Massachusetts, USA). The iris was imaged by SSOCT (SS-1000, CASIA, Tomey, Nagoya, Japan). The associations of surface features with iris parameters were analysed using a generalised estimating equation. Results A total of 1704 subjects (3297 eyes) were included in ...

    3. Automatic Feature Extraction of Optical Coherence Tomography for Lamina Cribrosa Detection

      Automatic Feature Extraction of Optical Coherence Tomography for Lamina Cribrosa Detection

      T his paper presents a framework to segment and extract key features automatically in Optical Coherence Tomography (OCT) scans. One of the main features to be detected is the Lamina Cribrosa (LC), which is an optic nerve head structure believed to play a crucial role in glaucomatous optic neuropathy. Detection of the LC aids in understanding pathogenesis and detection of glaucoma. Automatic segmentation allows a quick and objective way of identifying the LC. In previous work, LC segmentation has been manual; hence, the aim is to achieve automatic and accurate segmentation. Automatic detection is a novel approach, and very important ...
