    1. Sensitivity and Specificity of Potential Diagnostic Features Detected Using Fundus Photography, Optical Coherence Tomography, and Fluorescein Angiography for Polypoidal Choroidal Vasculopathy

      Sensitivity and Specificity of Potential Diagnostic Features Detected Using Fundus Photography, Optical Coherence Tomography, and Fluorescein Angiography for Polypoidal Choroidal Vasculopathy

      Importance The use of indocyanine green angiography (ICGA) is a criterion standard for diagnosing polypoidal choroidal vasculopathy (PCV), an endemic and common cause of vision loss in Asian and African individuals that also presents in white individuals. However, the use of ICGA is expensive, invasive, and not always available at clinical centers. Therefore, knowing the value of certain features detected using fundus photography (FP), optical coherence tomography (OCT), and fluorescein angiography (FA) to diagnose PCV without ICGA could assist ophthalmologists to identify PCV when ICGA is not readily available. Objective To explore the sensitivity, specificity, and predictive accuracy of potential ...

    2. Color Fundus Photography, Optical Coherence Tomography, and Fluorescein Angiography in Diagnosing Polypoidal Choroidal Vasculopathy

      Color Fundus Photography, Optical Coherence Tomography, and Fluorescein Angiography in Diagnosing Polypoidal Choroidal Vasculopathy

      Purpose To determine sensitivity and specificity of polypoidal choroidal vasculopathy (PCV) diagnosis using color fundus photography (CFP), optical coherence tomography (OCT) and fundus fluorescein angiography (FFA) without indocyanine-green angiography (ICGA). Design Validity analysis. Methods Treatment-naïve eyes with serous/serosanguinous maculopathy undergoing CFP, OCT, FFA and ICGA imaging before treatment at a university-hospital in Thailand (January 2013 to June 2015) were identified. Images of each subject were categorized into 4 sets (set A: CFP; set B: CFP+OCT; set C: CFP+FFA; set D: CFP+OCT+FFA). Six graders, 3 from Thailand (PCV endemic area) and 3 from U.S ...

    3. Spectral-domain optical coherence tomography of macula in myopia

      Spectral-domain optical coherence tomography of macula in myopia

      The aim of this study is to determine the associations between regional macular thickness and gender, age, axial length, and degree of myopia in young and middle-aged healthy myopic eyes. One hundred and seventy-one subjects with −0.5 diopters of myopia or worse underwent prospective macular thickness measurement by Spectralis spectral-domain optical coherence tomography. Subjects’ mean age was 32.40 ± 8.25 years (range 18 to 49 years), with 45 % being male. The mean degree of myopia was −4.57 ± 3.52 diopters, with a mean axial length of 25.09 ± 1.67 mm. Multivariate regression analysis demonstrated significantly thicker ...

    4. Macular thickness measured by spectral-domain optical coherence tomography in healthy Thai eyes

      Macular thickness measured by spectral-domain optical coherence tomography in healthy Thai eyes

      Purpose To describe the macular thickness measured by spectral-domain optical coherence tomography (SD-OCT) in healthy eyes of Thai people. Design Prospective cross-sectional study. Methods Three hundred sixty-eight healthy participants underwent a comprehensive ophthalmic examination, including Spectralis SD-OCT scanning, at Chiang Mai University Hospital. The images were obtained over maculae, using a high-speed volumetric raster scan pattern with lines 240 μm apart. Information was collected from both eyes of each person, with only the right one being used unless it was found to be ineligible (in which case the left eye was studied). A mean retinal thickness was calculated based on ...
