Contrast-Enhanced Magnetic Resonance Angiography of the Pulmonary Vasculature

1998

Magnetic resonance angiography (MRA) has been established as a powerful noninvasive imaging modality. Its applications to the study of the pulmonary vasculature have been hampered by a multitude of factors, such as respiratory and cardiac motion artifacts, saturation problems, long acquisition times

Polypoidal choroidal vasculopathy in pachychoroid: combined treatment with photodynamic therapy and aflibercept

2022

Abstract Introduction To evaluate the effects of combined therapy using intravitreal Aflibercept (IVA) and photodynamic therapy (PDT) on polypoidal choroidal vasculopathy related to pachychoroid disease (PPCV).Methods Patients with PPCV were treated with PDT combined with 3 IVA injections on a monthly basis, followed by pro re nata criteria. The 12-month follow-up consisted of multiple revaluations of visual acuity and SSOCT parameters of clinical activity.Results Nineteen eyes were included in the study; mean age was 65.5 years. Visual acuity improved after 12 months (0.35 ± 0.25 to 0.2 ± 0.20 logMAR, p = 0.005). Percentage of eyes with intraretinal and subretinal fluid reduced from baseli…

Delayed Suprachoroidal Hemorrhage After Pars Plana Vitrectomy: Five-Year Results of a Retrospective Multicenter Cohort Study

2015

Purpose To determine the incidence, risk factors, and outcomes of delayed suprachoroidal hemorrhage after vitrectomy. Design Retrospective multicenter cohort study. Methods All consecutive patients who underwent primary vitrectomy, from January 2009 to December 2014, at 4 tertiary vitreoretinal centers in Italy were enrolled. Patient demographics and systemic, ophthalmic, operative, and postoperative data from all centers were extracted from the electronic record system using standardized data collection forms. All eyes that developed delayed suprachoroidal hemorrhage within 48 hours of the end of the vitrectomy were identified as the delayed suprachoroidal hemorrhage group; all other eyes …

Intravitreal pegaptanib sodium for refractory pseudophakic macular oedema.

2008

Evaluate the efficacy of intravitreal pegaptanib sodium (Macugen®) in refractory pseudophakic cystoid macular oedema (CME). Prospective, nonrandomized, interventional case series. Four eyes of four patients with refractory pseudophakic CME to pars plana vitrectomy and intravitreal bevacizumab and triamcinolone, were treated with pegaptanib sodium, with a mean follow up of 4 months. Pre- and postinfection examinations included assessment of best-corrected visual acuity (BCVA) using the Early Treatment Diabetic Retinopathy Study chart (ETDRS), fluorescein angiography (FA), and optical coherence tomography (OCT). Visual acuity increased in all patients after intravitreal pegaptanib sodium. OCT…

Vascular changes after vitrectomy for rhegmatogenous retinal detachment: optical coherence tomography angiography study

2020

Purpose: To analyse the postoperative foveal avascular zone (FAZ) area, superficial vessel density (SVD) and deep vessel density (DVD) and their correlation with functional (best-corrected visual acuity, BCVA) and anatomical outcomes (foveal macular thickness, FMT) after surgery for rhegmatogenous retinal detachment (RRD) repair. Method: Patients with RRD eyes, successfully treated with a single pars plana vitrectomy (PPV) with gas tamponade and a minimum 12 months follow-up, were re-examined. Foveal avascular zone (FAZ) area, SVD, DVD and FMT were evaluated by using optical coherence tomography angiography (OCTA) and compared to fellow eye. Results: Fifty-six patients with macula-on and 37…
