    5. Retinal Nerve Fiber and Optic Disc Morphology in Patients with Human Immunodeficiency Virus Using the Heidelberg Retina Tomography 3

      Retinal Nerve Fiber and Optic Disc Morphology in Patients with Human Immunodeficiency Virus Using the Heidelberg Retina Tomography 3
      Purpose To use novel confocal scanning ophthalmoscopy technology to test hypothesis that HIV-seropositive patients without history of retinitis with a history of a low CD4 count are more likely to have damage to their retinal nerve fiber layer (RNFL) when compared to patients with high CD4 count. In addition, we compared optic disc morphologic changes with glaucoma. Design Cross-sectional study. Participants and Controls 171 patients were divided into four groups ...

      Fluorescein Angiography Versus Optical Coherence Tomography-Guided Planning for Macular Laser Photocoagulation in Diabetic Macular Edema
      Purpose: To compare laser photocoagulation plans for diabetic macular edema (DME) using fluorescein angiography (FA) versus optical coherence tomography (OCT) thickness map superimposed on the retina. Methods: Fourteen eyes with DME undergoing navigated laser photocoagulation with navigated photocoagulator had FA taken using the same instrument. Optical coherence tomography central retinal thickness map was imported to the photocoagulator and with same magnification aligned onto the retina. Three retina specialists placed laser ...

    7. Optical Coherence Tomography Findings of the Vitreoretinal Interface in Asymptomatic Fellow Eyes of Patients With Acute Posterior Vitreous Detachment

      Optical Coherence Tomography Findings of the Vitreoretinal Interface in Asymptomatic Fellow Eyes of Patients With Acute Posterior Vitreous Detachment
      Purpose: To describe the vitreoretinal interface of the asymptomatic fellow eyes of patients with acute unilateral posterior vitreous detachment (PVD) based on biomicroscopic examination and spectral domain optical coherence tomography. Methods: Sixty-five eyes of 65 consecutive patients with acute unilateral PVD were examined by slit-lamp, indirect ophthalmoscopy, and spectral domain optical coherence tomography. The state of PVD in different retinal locations and premacular pocket were assessed and graded using spectral ...

    8. Safety and Efficacy of Oral Fluorescein Angiography in Detecting Macular Edema in Comparison With Spectral-Domain Optical Coherence Tomography

      Safety and Efficacy of Oral Fluorescein Angiography in Detecting Macular Edema in Comparison With Spectral-Domain Optical Coherence Tomography
      Purpose: To evaluate the safety of oral fluorescein angiography (FA) and to compare its efficacy in detection of macular edema (ME) with spectral-domain optical coherence tomography (SD-OCT). Methods: Results of imaging studies for 1,928 eyes of 1,019 patients who had simultaneously undergone both oral FA and SD-OCT by a confocal laser ophthalmoscope were reviewed. Sensitivity in detecting ME, discrepancy rate, and "kappa" agreement were determined for both the ...

    9. Correlation of Spectral Domain Optical Coherence Tomography Characteristics With Visual Acuity in Eyes With Subfoveal Scarring After Treatment for Wet Age-Related Macular Degeneration

      Correlation of Spectral Domain Optical Coherence Tomography Characteristics With Visual Acuity in Eyes With Subfoveal Scarring After Treatment for Wet Age-Related Macular Degeneration
      Purpose: Correlating spectral domain optical coherence tomography characteristics with final best-corrected visual acuity (BCVA) in eyes with subfoveal scarring after treatment for wet age-related macular degeneration. Methods: Seventy-nine eyes from 64 subjects, who developed subfoveal scarring after treatment of wet age-related macular degeneration, were retrospectively studied. Spectral domain optical coherence tomography characteristics were analyzed, including percentage disruption of inner segment/outer segment junction and external limiting membrane, central macular thickness ...

      Repeatability and reproducibility of manual choroidal volume measurements using enhanced depth imaging optical coherence tomography
      Purpose: To evaluate the repeatability and reproducibility of manual choroidal volume (CV) measurements on spectral-domain optical coherence tomography (SD-OCT) using enhanced depth imaging (EDI). Methods: Sixty eyes of 32 patients with or without any ocular chorio-retinal diseases were enrolled prospectively. Thirty-one choroidal scans were performed on each eye centered at the fovea using a raster protocol. Two masked observers demarcated choroidal boundaries using the built-in automated retinal segmentation software on ...
