    2. Macular morphologic findings on optical coherence tomography after microincision vitrectomy for proliferative diabetic retinopathy

      Macular morphologic findings on optical coherence tomography after microincision vitrectomy for proliferative diabetic retinopathy
      Purpose To investigate macular morphology on spectral-domain optical coherence tomography (SD-OCT) images after microincision vitrectomy for vitreous hemorrhage associated with proliferative diabetic retinopathy (PDR). Methods In this retrospective case series, 69 eyes (57 consecutive patients) that underwent 23-gauge microincision vitrectomy for vitreous hemorrhage due to PDR were investigated. Qualitative and quantitative characteristics on SD-OCT images [central retinal thickness, external limiting membrane (ELM), and the ellipsoid zone, epiretinal membranes involving the ...

    3. The Application of Extended Field Imaging to Optical Coherence Tomography

      The Application of Extended Field Imaging to Optical Coherence Tomography
      Since its invention, optical coherence tomography (OCT) has made remarkable advancements in both image resolution and acquisition speed. 1,2 With improvements in both hardware and software, higher resolution and less noisy retinal cross-sectional images can be obtained noninvasively. 3 Recent improvements to commercially available OCT systems have also included increasing scan length. For example, most spectral-domain OCT machines provide line scans that are approximately 9 mm in length. Therefore ...

    4. Analysis of Fundus Shape in Highly Myopic Eyes by Using Curvature Maps Constructed from Optical Coherence Tomography

      Analysis of Fundus Shape in Highly Myopic Eyes by Using Curvature Maps Constructed from Optical Coherence Tomography
      Purpose To evaluate fundus shape in highly myopic eyes using color maps created through optical coherence tomography (OCT) image analysis. Methods We retrospectively evaluated 182 highly myopic eyes from 113 patients. After obtaining 12 lines of 9-mm radial OCT scans with the fovea at the center, the Bruchs membrane line was plotted and its curvature was measured at 1-m intervals in each image, which was reflected as a color topography ...

    5. High-Resolution Imaging of Photoreceptors in Macular Microholes [Retina]

      High-Resolution Imaging of Photoreceptors in Macular Microholes [Retina]
      Purpose. To assess photoreceptor structure in macular microholes by using adaptive optics scanning laser ophthalmoscopy (AO-SLO) and spectral-domain optical coherence tomography (SD-OCT) and compare with visual acuity. Methods. Fourteen eyes from 12 patients with macular microholes underwent a full ophthalmologic examination and imaging with a fundus camera, SD-OCT, and an original prototype AO-SLO system at each visit. Results. All eyes had a cone outer segment tip line disruption and a ...

    6. Effects of Sex and Age on the Normal Retinal and Choroidal Structures on Optical Coherence Tomography

      Effects of Sex and Age on the Normal Retinal and Choroidal Structures on Optical Coherence Tomography
      Optical coherence tomography (OCT) has become an essential tool in ophthalmology. Advances in OCT technology have made it possible to measure the thickness of the retina, specific retinal layers, and the choroid. In the present study, the body of the literature documenting the normal retinal and choroidal thickness are reviewed and the effects of sex, age, and axial length on retinal/choroidal thickness are discussed. Macular, retinal layer, and choroidal ...

    8. OPTICAL COHERENCE TOMOGRAPHIC REFLECTIVITY OF CYSTOID SPACES IS RELATED TO RECURRENT DIABETIC MACULAR EDEMA AFTER TRIAMCINOLONE

      OPTICAL COHERENCE TOMOGRAPHIC REFLECTIVITY OF CYSTOID SPACES IS RELATED TO RECURRENT DIABETIC MACULAR EDEMA AFTER TRIAMCINOLONE
      Purpose: To determine the association between reflectivity levels in foveal cystoid spaces on optical coherence tomography images and the course of the logarithm of the minimum angle of resolution (logMAR) after triamcinolone acetonide treatment for diabetic macular edema. Methods: We retrospectively reviewed 58 consecutive eyes treated with an intravitreal or sub-Tenon's injection of triamcinolone acetonide for diabetic macular edema. The foveal cystoid spaces within central 1 mm were circumscribed ...

      Feature Of The Week 3/2/14: Erasmus MC Investigates Fusion of OCT and Coronary Angiography for Accurate Assessment of the Local Blood Flow Patterns
      Intravascular ultrasound (IVUS)-based reconstructions have been traditionally used to examine the effect of endothelial shear stress (ESS) on neointimal formation. The aim of this analysis is to compare the association between ESS and neointimal thickness (NT) in models obtained by the fusion of optical coherence tomography (OCT) and coronary angiography and in the reconstructions derived by the integration of IVUS and coronary angiography. We analyzed data from six patients ...

    10. Macular Choroidal Thickness and Volume of Eyes with Reticular Pseudodrusen Using Swept-Source Optical Coherence Tomography

      Macular Choroidal Thickness and Volume of Eyes with Reticular Pseudodrusen Using Swept-Source Optical Coherence Tomography
      Purpose To investigate the choroidal thickness/volume of eyes with reticular pseudodrusen using high-penetration swept-source optical coherence tomography (SS-OCT) and to evaluate the choroidal vasculature changes using en face images. Design Prospective cross sectional study. Methods Thirty-eight eyes with reticular pseudodrusen and 14 normal eyes were studied with prototype SS-OCT. Eyes with reticular pseudodrusen were classified into 3 subgroups: eyes without late age-related macular degeneration (AMD) (group1), eyes with neovascular ...
