    2. COmbined multimodal analysis of Peripheral Retinal and mAcular circulation in Diabetic Retinopathy (COPRA Study)

      COmbined multimodal analysis of Peripheral Retinal and mAcular circulation in Diabetic Retinopathy (COPRA Study)
      Importance The relationship between peripheral retinal capillary non-perfusion with central NP is non-linear. Objective To systematically examine the relationships between the microvascular indices that are measured on OCTA and the presence and extent of peripheral non-perfusion in persons with diabetic retinopathy Design Retrospective cross-sectional study of patients with varying degrees of diabetic retinopathy ; Setting: Two large tertiary referral retina clinics Participants Eighty-two eyes of forty-five patients with varying degrees of ...

    3. Confocal infrared imaging with optical coherence tomography provides superior detection of a number of common macular lesions compared to colour fundus photography

      Confocal infrared imaging with optical coherence tomography provides superior detection of a number of common macular lesions compared to colour fundus photography
      Purpose To compare diagnostic accuracy of confocal infrared reflectance (IR), with and without optical coherence tomography (OCT), to colour fundus photography (CFP) in the Northern Ireland Cohort for the Longitudinal Study of Ageing (NICOLA) Study. Methods Cross‐sectional observational study of participants in NICOLA. CFP, IR and IR/OCT of 640 eyes were graded for hard, soft and reticular pseudodrusen; geographic atrophy; choroidal neovascularisation; naevus; epiretinal membrane; and haemorrhages. Test ...

    4. Tomographic Biomarkers Predicting Progression to Fibrosis in Treated Neovascular Age-Related Macular Degeneration: A Multimodal Imaging Study

      Tomographic Biomarkers Predicting Progression to Fibrosis in Treated Neovascular Age-Related Macular Degeneration: A Multimodal Imaging Study
      Purpose To describe the photoreceptorretinal pigment epithelium (RPE) interface changes and to analyze the relationships between these features and hyperreflective material (HRM) with scarring and atrophy at the macula of patients with neovascular age-related macular degeneration (nAMD). Design Retrospective single-center observational study. Participants A total of 150 eyes from 144 patients with naive nAMD were included. Methods All patients had OCT (HRA-OCT Spectralis, Heidelberg Engineering, Heidelberg, Germany) at baseline and ...

    6. Changes in Neovascular Lesion Hyperreflectivity After Anti-VEGF Treatment in Age-Related Macular Degeneration: An Integrated Multimodal Imaging Analysis

      Changes in Neovascular Lesion Hyperreflectivity After Anti-VEGF Treatment in Age-Related Macular Degeneration: An Integrated Multimodal Imaging Analysis
      Purpose : To correlate presence of hyperreflective material (HRM) on spectral-domain optical coherence tomography (SD-OCT) with color fundus photography (CFP) in patients with different subtypes of neovascular age-related macular degeneration (n-AMD). Methods : Retrospective assessments were made at baseline and months 1, 3, and 12 after initiation of treatment. At baseline, CFP images were graded for the presence of blood, fibrin and lipid exudates, and retinal angiograms for n-AMD subtype. At the ...
