  1. Spectral-Domain Optical Coherence Tomographic Findings in Myopic Foveoschisis

    Explore Article LWW Online (Apr 16 2010) Ophthalmology

    Purpose: The purpose of this study was to investigate the sensitivity of various scan modes of spectral-domain optical coherence tomography (SD-OCT) for detecting pathologies that may accompany myopic foveoschisis, which is important for making surgical decisions and planning surgical strategies for myopic foveoschisis. Methods: Twenty-one eyes of 18 patients were diagnosed with myopic foveoschisis by SD-OCT. Patients were examined with SD-OCT using both a five-line raster scan and a three-dimensional scan at the same visit. The detection rates of pathologies such as macular hole, epiretinal membrane, retinal vascular microfolds, internal limiting membrane detachment, paravascular microhole, and photoreceptor inner and outer ...

  2. Imaging of Titanium:Sapphire Laser Retinal Injury by Adaptive Optics Fundus Imaging and Fourier-Domain Optical Coherence Tomography

    Explore Article American Journal of Ophthalmology (Mar 26 2009) Ophthalmology

    Purpose: To examine and observe the subtle retinal injuries caused by a titanium:sapphire laser with a high-resolution adaptive optics (AO) fundus camera and with Fourier-domain optical coherence tomography (FD-OCT).Design: Observational case series.Methods: Four eyes of 2 individuals who experienced an accidental exposure to reflected light from a titanium:sapphire laser were examined. High-resolution retinal images were obtained with the AO fundus camera and by FD-OCT, and the images were compared with the findings obtained by standard clinical tests, including the Amsler test and fluorescein angiography (FA).Results: The photoreceptor mosaic was absent in a localized area of the fovea in the images ...

  3. Retinal and choroidal biometry in highly myopic eyes using spectral-domain optical coherence tomography

    Explore Article iovs.org (Mar 12 2009) Ophthalmology

    Purpose: Morphologic changes of the retina and choroid are closely related with high myopia-related pathologies. We evaluated the morphologic characteristics of normal highly myopic eyes. Patients and methods: Thirty-one phakic highly myopic eyes with no posterior abnormalities in 18 patients (mean+/-SD age 51.7+/-11.4 y) were enrolled. Retinal/choroidal thickness at the fovea 1.5 mm superiorly, inferiorly, nasally, and temporally, and the choroidal curvature were measured in the 512x128 3D scan mode with spectral domain optical coherence tomography. Degree of posterior staphyloma was determined as the sum of the vertical distance from the retinal pigment epithelial line beneath the fovea to the ... (Read Full Article)

  4. Foveal Microstructure and Visual Acuity after Retinal Detachment Repair: Imaging Analysis by Fourier-Domain Optical Coherence Tomography

    Explore Article OphSource (Jan 14 2009) Ophthalmology

    Purpose To evaluate foveal microstructural changes in eyes with anatomically successful repair of rhegmatogenous retinal detachments (RRDs). Design Retrospective, consecutive, observational case series. Participants Fifty-three eyes of 51 consecutive patients with macula-on RRDs (15 eyes) or macula-off RRDs (38 eyes) after anatomically successful surgical repair. Methods A microscopic fundus examination was conducted followed by Fourier-domain optical coherence tomography (FD-OCT) to assess the postoperative foveal microstructure. The correlation between the postoperative best-corrected visual acuity (BCVA) and microstructural findings at the fovea was evaluated. Main Outcome Measures Images of the foveal microstructure obtained by FD-OCT and the BCVA measured on the same ... (Read Full Article)

  6. Adaptive Optics Fundus Camera to Examine Localized Changes in the Photoreceptor Layer of the Fovea

    Explore Article OphSource (Sep 30 2008) Ophthalmology

    Purpose: To examine highly localized photoreceptor disruptions in the fovea by a high-resolution adaptive optics (AO) fundus camera combined with Fourier-domain optical coherence tomography (FD OCT).Design: Observational case series.Participants: Three eyes of 3 patients who showed dark foveal spots by slit-lamp biomicroscopy.Methods: Three patients who reported metamorphopsia but showed no changes in the retina in conventional fundus photographs were examined. High-resolution retinal images were obtained with the AO fundus camera and by FD OCT. The images were compared with the findings obtained by standard clinical tests, including Amsler charts and fluorescein angiography (FA).Main Outcome Measures: Quantitative measurements of the area ...

  7. Morphologic Changes in Acute Central Serous Chorioretinopathy Evaluated by Fourier-Domain Optical Coherence Tomography

    Explore Article OphSource (Aug 31 2008) Ophthalmology

    Objective: To investigate morphologic alterations around fluorescein leakage sites using Fourier-domain optical coherence tomography (FD OCT) in acute central serous chorioretinopathy (CSC).Design: Observational case series.Participants: Twenty-one eyes with acute CSC with subjective symptoms for under 3 months.Methods: Patients underwent measurement of visual acuity, fundus observations, and FD OCT examinations at every visit with the intervals of 2 to 4 weeks until subretinal fluid (SRF) resolved. Fluorescein angiography was performed at baseline to confirm dye leakage sites. Horizontal and vertical OCT scans (B-scans and consecutive raster scans) of the fovea and fluorescein leakage sites were obtained.Main Outcome Measures: Morphologic changes in ...
