    1. Imaging of Corneal Neovascularization: Optical Coherence Tomography Angiography and Fluorescence Angiography

      Imaging of Corneal Neovascularization: Optical Coherence Tomography Angiography and Fluorescence Angiography

      Purpose : The purpose of this study was to compare optical coherence tomography angiography (OCTA) and indocyanine green angiography (ICGA) for the assessment of corneal neovascularization (CoNV). Methods : Patients with CoNV extending at least 3 mm into the cornea were included. All patients underwent corneal imaging at the same visit. Images were recorded using the AngioVue OCTA system (Optovue, Inc.) with the long corneal adaptor module (CAM-L). ICGA images were recorded with fluorescent filters using the Heidelberg system (HRA2 Scanning Laser Ophthalmoscope; Heidelberg Engineering). Images were graded for quality by two independent observers. Vessel parameters: area, number, diameter, branch and end ...

    2. Deformation velocity imaging using optical coherence tomography and its applications to the cornea

      Deformation velocity imaging using optical coherence tomography and its applications to the cornea

      Optical coherence tomography (OCT) can monitor human donor corneas non-invasively during the de-swelling process following storage for corneal transplantation, but currently only resultant thickness as a function of time is extracted. To visualize and quantify the mechanism of de-swelling, we present a method exploiting the nanometer sensitivity of the Fourier phase in OCT data to image deformation velocities. The technique was demonstrated by non-invasively showing during de-swelling that osmotic flow through an intact epithelium is negligible and removing the endothelium approximately doubled the initial flow at that interface. The increased functional data further enabled the validation of a mathematical model ...

    3. Morphometric characterisation of pterygium associated with corneal stromal scarring using high-resolution anterior segment optical coherence tomography

      Morphometric characterisation of pterygium associated with corneal stromal scarring using high-resolution anterior segment optical coherence tomography

      Aims To investigate the role of high-resolution anterior segment optical coherence tomography (HR-ASOCT) in the assessment of pterygia. Methods Single centre cross-sectional study. Patients with primary pterygium and/or pingueculae were included. Clinical assessment included HR-ASOCT, colour photography, keratometry followed by histology. Associations were tested between HR-ASOCT features of the pterygium and the degree of corneal scarring and elastotic degeneration, astigmatism and best-corrected visual acuity. Results 29 eyes of 26 patients with pterygium and 6 patients with pinguecula were included. Apical anterior stromal scarring was found in 23 cases (79.3%) reaching a mean depth of 68.8±21.7 ...

    4. High resolution corneal and single pulse imaging with line field spectral domain optical coherence tomography

      High resolution corneal and single pulse imaging with line field spectral domain optical coherence tomography

      We report the development of a Spectral Domain Line Field Optical Coherence Tomography (LF-OCT) system, using a broad bandwidth and spatial coherent Super-Continuum (SC) source. With conventional quasi-Continuous Wave (CW) setup we achieve axial resolutions up to 2.1 μm in air and 3D volume imaging speeds up to 213 kA-Scan/s. Furthermore, we report the use of a single SC pulse, of 2 ns duration, to temporally gate an OCT B-Scan image of 70 A-Scans. This is the equivalent of 35 GA-Scans/s. We apply the CW setup for high resolution imaging of the fine structures of a human ...
