    5. Choroidal assessment in idiopathic panuveitis using optical coherence tomography

      Choroidal assessment in idiopathic panuveitis using optical coherence tomography
      Background Idiopathic panuveitis is a diagnosis of exclusion that lacks distinguishing features on fluorescein and indocyanine green angiography. Choroidal hypoperfusion or ischaemia has been implicated in panuveitis of different aetiologies. In this study, we use enhanced depth imaging optical coherence tomography (OCT) to examine the choroid and its vasculature in patients with this disease. Methods In this retrospective, cross-sectional study, OCT-derived measurements of retinal and choroidal thickness were obtained after ...

    6. Repeatability and Reproducibility of Choroidal Vessel Layer Measurements in Diabetic Retinopathy using Enhanced Depth Optical Coherence Tomography

      Repeatability and Reproducibility of Choroidal Vessel Layer Measurements in Diabetic Retinopathy using Enhanced Depth Optical Coherence Tomography
      Purpose: To describe novel segmentation protocols for choroidal layers - Sattler's medium and Haller's large vessel layers, using enhanced depth imaging optical coherence tomography (EDI-OCT), and to examine the repeatability and reproducibility of these measurements in eyes with diabetic retinopathy. Methods: Fifty-one patients with Type 2 diabetes mellitus were imaged using custom EDI scanning protocols. Detailed segmentation was performed to quantify the retina, choroid, Haller's large, and Sattler ...

    7. Evaluation of Age-related Macular Degeneration With Optical Coherence Tomography

      Evaluation of Age-related Macular Degeneration With Optical Coherence Tomography
      Abstract: Age-related macular degeneration (AMD) is the leading cause of severe visual loss in people aged 50 years or older in the developed world. In recent years, major advances have been made in the treatment of AMD, with the introduction of anti-angiogenic agents, offering the first hope of significant visual recovery for patients with neovascular AMD. In line with these advances, a new imaging modalityoptical coherence tomography (OCT)has emerged ...

    8. Assessment of Differential Pharmacodynamic Effects using Optical Coherence Tomography in Neovascular Age-Related Macular Degeneration

      Assessment of Differential Pharmacodynamic Effects using Optical Coherence Tomography in Neovascular Age-Related Macular Degeneration
      Purpose: To assess the differential pharmacodynamic effects of bevacizumab (Avastin), pegaptanib (Macugen), and verteporfin photodynamic therapy (PDT), using novel OCT parameters, in a recently completed phase III/IV clinical trial. Methods: Data from 122 patients participating in the Avastin (Bevacizumab) for Choroidal neovascularization (ABC) trial, were evaluated. Stratus OCT images were analyzed using custom software - changes in volume of the neurosensory retina, subretinal fluid (SRF), pigment epithelium detachment (PED), and ...
