      Age-Related Macular Degeneration Staging by Color Fundus Photography vs. Multimodal Imaging—Epidemiological Implications (The Coimbra Eye Study—Report 6)
      Epidemiology of age-related macular degeneration (AMD) is based on staging systems relying on color fundus photography (CFP). We aim to compare AMD staging using CFP to multimodal imaging with optical coherence tomography (OCT), infra-red (IR), and fundus autofluorescence (FAF), in a large cohort from the Epidemiologic AMD Coimbra Eye Study. All imaging exams from the participants of this population-based study were classified by a central reading center. CFP images were ...

      Aims: To present an authoritative, universal, easy-to-use morphologic classification of diabetic maculopathy based on spectral domain optical coherence tomography. Methods: The first draft of the project was developed based on previously published classifications and a literature search regarding the spectral domain optical coherence tomography quantitative and qualitative features of diabetic maculopathy. This draft was sent to an international panel of retina experts for a first revision. The panel met at ...

      Sexual Dimorphism of the Adult Human Retina Assessed by Optical Coherence Tomography
      In this work, we imaged the retina of healthy age-matched female and male subjects with optical coherence tomography to assess the existence of localised sex-related differences in the retina. Texture analysis revealed statistically significant differences spread over the different layers of the neuroretina, particularly at the ganglion cell, inner plexiform and inner nuclear layers, and also spread in the macula. These results suggest that sexual dimorphism is expressed in the ...

      Microperimetry in age-related macular degeneration: association with macular morphology assessed by optical coherence tomography
      Background/aims Microperimetry is a technique that is increasingly used to assess visual function in age-related macular degeneration (AMD). In this study, we aimed to evaluate the relationship between retinal sensitivity measured with macular integrity assessment (MAIA) microperimetry and optical coherence tomography (OCT)-based macular morphology in AMD. Methods Prospective, cross-sectional study. All participants were imaged with colour fundus photographs used for AMD staging (Age-Related Eye Disease Study scale), spectral-domain ...

      OPTICAL COHERENCE TOMOGRAPHY LEAKAGE IN NEOVASCULAR AGE-RELATED MACULAR DEGENERATION
      Purpose: To test optical coherence tomography leakage in the identification and quantification of choroidal neovascularizationrelated fluid, its change after antivascular endothelial growth factor therapy in neovascular age-related macular degeneration eyes and its relation to functional outcome. Methods: Prospective analysis of a cohort of neovascular age-related macular degeneration cases treated with 2.0-mg intravitreal aflibercept. Eyes included were analyzed before, 1-week, and 1-month after one injection. Best-corrected visual acuity was assessed ...

      Choroidal thickness and vascular density in macular telangiectasia type 2 using enface swept-source optical coherence tomography
      Purpose To investigate the choroidal thickness (CT) and choroidal vascular densities (CVD) of patients with macular telangiectasia type 2 (MacTel2) and their association with other multimodal imaging features, using swept-source optical coherence tomography (SS-OCT). Methods Prospective, cross-sectional study. Consecutive patients with MacTel2 along with controls without any macular disease were included. Fundus photography, confocal blue reflectance, near-infrared reflectance, autofluorescence, fluorescein angiography, spectral domain OCT and SS-OCT were performed. Images were ...

      MEASUREMENTS OF RETINAL FLUID BY OPTICAL COHERENCE TOMOGRAPHY LEAKAGE IN DIABETIC MACULAR EDEMA: A Biomarker of Visual Acuity Response to Treatment
      Purpose: To evaluate the effects of antivascular endothelial growth factor treatment on retinal fluid in patients with diabetic macular edema by using optical coherence tomography leakage (OCT-L), a new method of quantifying sites of lower than normal optical reflectivity (LOR) in OCT, and to correlate these findings with best-corrected visual acuity (BCVA) response. Methods: Prospective analysis of 21 eyes with diabetic macular edema , naive to antivascular endothelial growth factor treatment ...

      Optical coherence tomography angiography characterization of acute and late stage Purtscher retinopathy
      Purpose: To report a case of Purtscher retinopathy imaged with optical coherence tomography angiography. Methods: Case-report. Left eye fundoscopic examination in a 21-year old male after a road traffic accident with chest compression revealed multiple peri-papillary cotton-wool spots and intra- and pre-retinal hemorrhages. A diagnosis of Purtscher retinopathy was assumed. Results: In both the superficial and deep retinal plexuses, acute stage optical coherence tomography angiography identified multiple irregular areas of ...

      Evaluation of choroidal lesions with swept-source optical coherence tomography
      Aims The aim of our study was to image choroidal lesions with swept-source optical coherence tomography (SS-OCT) and to identify the morphological characteristics associated with optimal visualisation. Methods This was a prospective, cross-sectional study. Patients with choroidal melanocytic lesions 3mm in thickness on B-scan ultrasonography were recruited. All participants underwent SS-OCT. On SS-OCT we evaluated qualitative (eg, lesion outline, detection of scleral-choroidal interface and quality of the image) and quantitative ...

Patients were evaluated with spectral-domain optical coherence tomography (OCT), enhanced depth imaging-OCT, and OCT angiography (OCTA). OCTA images were processed to generate maps of the vessel density and perfusion density of the superficial and deep retinal layers (SRL ...
