      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 ...

      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 ...

      Multimodal Evaluation of the Fellow Eye of Patients with Retinal Angiomatous Proliferation
      Introduction: We conducted a multimodal, cross-sectional evaluation. Methods: Eyes were divided into 4 study groups: controls, early/intermediate age-related macular degeneration (AMD), fellow eyes of retinal angiomatous proliferation (RAP), and RAP eyes. 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 ...

      Heart transplant coronary artery disease: Multimodality approach in percutaneous intervention
      Coronary artery disease is the most important cause of late morbidity and mortality after heart transplantation. It is usually an immunologic phenomenon termed cardiac allograft vasculopathy, but can also be the result of donor-transmitted atherosclerosis. Routine surveillance by coronary angiography should be complemented by intracoronary imaging, in order to determine the nature of the coronary lesions, and also by assessment of their functional significance to guide the decision whether to ...

      Optical Coherence Tomography (OCT) is a non-invasive optical imaging technique capable of producing 2D images or 3D reconstructions of nonhomogeneous samples. OCT is mainly used in ophthalmology as a powerful tool for the early diagnosis of ocular diseases. With OCT it is possible to obtain high resolution cross-sectional images of ocular structures, such as the retina or the anterior segment. An OCT platform for ocular image acquisition is being developed ...
