Methods In this cross-sectional and observational study, 22 eyes of 11 patients diagnosed with SC were included. All patients underwent blue-light fundus autofluorescence (spectralis Heidelberg retinalangiography+OCT) and swept-source OCT-A (AngioPlex Elite 9000 SS-OCT, Carl Zeiss Meditech) to analyse qualitative features and choroidal vessel ...

      OPTICAL COHERENCE TOMOGRAPHY ANGIOGRAPHY FEATURES OF ANGIOID STREAKS
      Purpose: To analyze the optical coherence tomography angiography features of eyes affected with angioid streaks (AS) and to evaluate their ability to predict choroidal neovascularization (CNV) activity. Methods: Angioid streaks were individuated from a pool of consecutive patients. Eyes with and without CNV were evaluated by multimodal imaging. Results: Thirty-eight eyes of 19 consecutive patients diagnosed with AS were included. Thirty of 38 eyes with CNV and 8 of 38 ...

    9. The role of intraoperative optical coherence tomography in pediatric hyphema: a case report

      The role of intraoperative optical coherence tomography in pediatric hyphema: a case report
      Intraoperative optical coherence tomography (iOCT) is a valuable tool during vitreoretinal surgery, helping the decision-making process. It is particularly useful in pediatric cases to evaluate the macular anatomy intraoperatively, avoiding further potentially dangerous surgery in children. The aim of this report is to describe the role of integrated iOCT in the management of traumatic hyphema in a pediatric patient. A 5-year-old girl was referred to our department with a history ...

      Refining Coats’ disease by ultra-widefield imaging and optical coherence tomography angiography
      Purpose The purpose of our study was to describe ultra-widefield (UWF) imaging and optical coherence tomography angiography (OCT-A) findings in affected and fellow eyes of patients with Coats disease. Methods Consecutive patients affected by Coats disease were prospectively recruited at the Department of Ophthalmology, San Raffaele Hospital, Milan, Italy in this cross-sectional, observational study. Patients underwent UWF color fundus photographs, UWF green autofluorescence, UWF fluorescein angiography (FA), optical coherence tomography ...

    13. Optical Coherence Tomography Angiography of Venous Loops in Diabetic Retinopathy

      Optical Coherence Tomography Angiography of Venous Loops in Diabetic Retinopathy
      Venous loops are relatively rare manifestations of diabetic retinopathy. The authors describe a case characterized by the development of a venous loop during a 3-year period. Optical coherence tomography angiography (OCTA) revealed a hyperintense signal from the lesion, attesting an ordinary flow into the venous loop. OCTA also showed an area of capillary loss in proximity of the lesion, which is in agreement with the proposed pathogenesis for venous loops ...

      To evaluate the optical coherence tomography angiography (OCT-A) features of a peripapillary intrachoroidal cavitation (ICC) in a patient with high myopia. A 67-year-old woman with ICC underwent visual acuity testing, refraction, slit-lamp biomicroscopy, dilated fundus examination, and OCT-A. The main findings are described in this case report. Best-corrected visual acuity was 20/20 in both eyes. Fundus examination revealed in the right eye a macular scar, a tilted disc along ...
