Association between parafoveal capillary nonperfusion and macular function in eyes with branch retinal vein occlusion

Purpose: To investigate the parafoveal perfusion status of the superficial and deep capillary layer in eyes with resolved branch retinal vein occlusion, and to study its effects on retinal sensitivity. Methods: In 27 enrolled eyes (27 patients) with resolved branch retinal vein occlusion, superficial and deep capillaries in the macular area (3- × 3-mm, centered on the fovea) were examined with optical coherence tomography angiography. Retinal sensitivity was examined with fundus-monitored microperimetry. Results: Optical coherence tomography angiography clearly showed the parafoveal superficial and deep capillaries individually. On the affected side of retina, 25 eyes (92.6%) showed capillary nonperfusion; 23 (85.2%) in the superficial layer and 22 (81.5%) in the deep layer. Capillary nonperfusions of both layers frequently overlapped and appeared to be connected with each other. Mean (±SD) retinal sensitivity at the superficial capillary nonperfusion was 19.2 ± 6.3 dB, significantly lower than that at the superficial capillary perfusion (24.4 ± 2.8 dB, P

Abstract OBJECTIVES: With a focus on renal function, the goal of this multicentre study was to assess peri-operative complications and late mortality of open surgical repair (OSR) of juxtarenal abdominal aortic aneurysms (JRAAA). METHODS: From February 2005 to December 2015, 315 consecutive patients undergoing elective OSR of a JRAAA in five French academic centres were evaluated retrospectively. The definition of JRAAA was an aortic aneurysm extending up to but not involving the renal arteries, i.e., a short neck

 Magnetic Particle Imaging (MPI) is a new, fast and three-dimensional imaging technique, which is considered promising for angiographies. As available MPI-scanners suffer from restricted spatial resolution and are mostly constructed for small animal imaging, no vessels within one organ have been depicted by MPI, yet. The purpose of this...

Abstract PURPOSE: To characterise the non-perfused areas (NPAs) in the superficial and deep capillary layers (sNPAs and dNPAs, respectively) in the posterior pole in proliferative diabetic retinopathy (PDR) on wide-field optical coherence tomography angiography (OCTA) images. METHODS: We retrospectively reviewed 104 eyes of 70 patients with PDR from whom wide-field swept source OCTA images were acquired. sNPAs and dNPAs were manually measured in each quadrant of the inner (1-3 mm diameter), intermediate (3-6 mm), and outer (6-10 mm) rings centred on the fovea. Two qualitative findings, th...

Objectives The aim of this study was to evaluate the feasibility of a computed tomography (CT) protocol enabling the visualization of the prostatic artery (PA) before prostatic artery embolization (PAE) in benign prostatic hyperplasia, which provides quantitative perfusion information of the prostate gland. Materials and Methods In this institutional review board–approved study, 22 consecutive patients (mean age, 67 ± 7 years) who were planned to undergo PAE underwent a dynamic CT scan of the pelvis (scan range, 22.4 cm; cycle time, 1.5 seconds; scan time, 44 seconds; 25 scan cycles; 70 kVp; 100 mAs) afte...

After the computed tomography coronary angiography, coronary stenosis was recognized at segment 3. Because inferior ischemia on stress myocardial perfusion scintigraphy with 201 thallium chloride induced by adenosine was found, we planned to perform the coronary intervention. After control coronary angiography, no significant stenosis was found in the right coronary artery. Intracoronary acetylcholine test...
