    3. TYPE 3 NEOVASCULARIZATION: Evolution, Association With Pigment Epithelial Detachment, and Treatment Response as Revealed by Spectral Domain Optical Coherence Tomography

      TYPE 3 NEOVASCULARIZATION: Evolution, Association With Pigment Epithelial Detachment, and Treatment Response as Revealed by Spectral Domain Optical Coherence Tomography

      Purpose: To demonstrate the evolution and treatment response of Type 3 neovascularization using spectral domain optical coherence tomography. Methods: We retrospectively analyzed 40 eyes treated with intravitreal anti-vascular endothelial growth factor therapy for Type 3 neovascularization over a variable follow-up period. Results: In 17 eyes, spectral domain optical coherence tomography captured the development of Type 3 neovascularization from punctate hyperreflective foci that preceded any outer retinal defect. The more mature Type 3 lesions were associated with outer retinal disruption and adjacent cystoid macular edema. In addition, 37 of 40 Type 3 lesions (93%) were associated with an underlying pigment epithelial ...

    5. Drusen and RPE atrophy automated quantification by optical coherence tomography in an elderly population

      Drusen and RPE atrophy automated quantification by optical coherence tomography in an elderly population

      Purpose Correlate OCT-derived measures of drusen and retinal pigment epithelium (RPE) atrophy areas (RAs) with demographic features in an elderly population. Patients and methods Subjects aged 50 years and older underwent Cirrus OCT scanning. Drusen area and volume were obtained from the macula within a central circle (CC) of 3   mm and a surrounding perifoveal ring (PR) of 3–5   mm, using the RPE analysis software (6.0). RA measurements were generated for the 6 × 6   mm 2 retinal area. Gender, age, smoking status, and systolic blood pressure (SBP) were considered. Results A total of 434 eyes were included. RA ...

    6. The cellular origins of the outer retinal bands in optical coherence tomography images

      The cellular origins of the outer retinal bands in optical coherence tomography images

      Purpose: To test the recently proposed hypothesis that the second OCT outer retinal band originates from the inner segment ellipsoid, by measuring: 1) thickness of this band within single cones, and 2) its respective distance from the external limiting membrane and outer segment tips. Methods: Adaptive optics OCT images were obtained from four normal subjects. Images were obtained at foveal (2∘) and perifoveal (5∘) locations. Cones (n = 9593) were identified and segmented in three dimensions using custom software. Features corresponding to bands 1, 2, and 3 were automatically identified. Thickness of band 2 was assessed in each cell by fitting ...

    7. Macular Thickness Measurements in Normal Eyes Using Spectral Domain Optical Coherence Tomography

      Macular Thickness Measurements in Normal Eyes Using Spectral Domain Optical Coherence Tomography

      BACKGROUND AND OBJECTIVE: Knowledge of the macular thickness in a normal population is important for the evaluation of pathological macular change. The purpose of this study was to define and measure macular thickness in normal eyes using spectral domain optical coherence tomography (OCT). PATIENTS AND METHODS: Fifty eyes from 50 normal subjects (29 men and 21 women, aged 22 to 68 years) were scanned with a prototype Cirrus HD-OCT system (5 µm axial resolution) (Carl Zeiss Meditec, Inc.). The proprietary Cirrus segmentation algorithm was used to produce retinal thickness maps, which were then averaged over 9 regions defined by a ...

    8. OCT in the Management of Macular Degeneration - Ophthalmology Education Lab

      OCT in the Management of Macular Degeneration - Ophthalmology Education Lab

      Advances in retinal pharmacology have significantly improved outcomes for patients with a range of chronic retinal conditions, including age-related macular degeneration, macular edema, retinal vascular disorders and diseases of the vitreomacular interface. Maximizing the efficacy of available treatments requires the appropriate use of optical coherence tomography (OCT) to diagnose these conditions and to monitor the efficacy of treatment. In this webinar series, leading clinicians and researchers will discuss the role of OCT in detecting structural changes associated with a range of retinal diseases and provide clinical pearls on using tools such as thickness maps, automated change analysis and angiography in ...

    University of Southern California

    University of Southern California is located in Los Angeles, a global center for arts, technology and international trade and is one of the world’s leading private research universities. USC enrolls more international students than any other U.S. university and offers extensive opportunities for internships and study abroad. With a strong tradition of integrating liberal and professional education, USC fosters a vibrant culture of public service and encourages students to cross academic as well as geographic boundaries in their pursuit of knowledge. The Keck School of Medicine is the medical school at the University of Southern California. Founded in 1885 as the USC College of Medicine, it was closed in 1921 and reopened in 1928 as the USC School of Medicine.
