Perifoveal exudative vascular anomalous complex (PEVAC) has been described by Querques et al. as a large isolated unilateral perifoveal aneurismal change

2021年2月25日 · 中心凹旁渗出性血管异常复合体（Perifoveal exudative vascular anomalous complex, PEVAC） ，2011年由Querques等首次报道，表现为在无其他视网膜、脉络膜疾病，无糖尿病、控制不佳的高血压等全身疾病的患者中出现的独立的、中心凹旁的血管瘤样异常，可伴有 …

黄斑中心凹旁渗出性血管异常复合体（pevac）是近年来发现的以黄斑中心凹旁孤立动脉瘤病变伴有出血与硬性渗出为特征的一类疾病。 其发病机制和病理进程现阶段尚未完全阐明。

PEVAC is an isolated, perifoveal, aneurysmal abnormality, occurring in otherwise healthy patients who may manifest other macular disease including AMD and myopic macular degeneration. PEVAC did not typically respond to anti-VEGF therapy, and may be associated with type 3 neovascularization.

2021年12月12日 · In 2017, studies across 15 centers showed that PEVAC is an isolated, perifoveal, angiomatous lesion that generally occurs in healthy patients but can also be accompanied by AMD and myopic macular degeneration. PEVAC has a slight or poor response to anti-VEGF treatments.

2020年12月1日 · In this report we describe the extended follow-up of a patient with PEVAC, initially without exudation, who subsequently developed exudation and was treated with intravitreal injections of anti-vascular endothelial growth factor (VEGF) followed by focal thermal laser photocoagulation.

2024年11月15日 · Objectives: This study aimed to describe the clinical, optical coherence tomography (OCT) and OCT angiography (OCTA) findings and characteristics in patients with perifoveal exudative vascular anomalous complex (PEVAC) and compare the macular vascular density with the age-matched control group.

PEVAC is defined by an isolated large perifoveal aneurysm, in the absence of retinal vascular or inflammatory diseases. In this series, we aimed to expand our understanding regarding this uncommon entity by describing the multimodal imaging findings in 15 patients identified at 4 retina referral centers worldwide.

Purpose: To report the angiographic and optical coherence tomography (OCT) features of isolated "perifoveal exudative vascular anomalous complex (PEVAC)", a peculiar clinical entity. Methods: A complete ophthalmologic examination was performed in two patients (a 82-year old woman [case 1]; a 52-year old man [case 2]) that were referred to our ...

2020年11月19日 · We observed evident differences in quantity of PEVAC compared with PEVAC-resembling lesions, which suggests that an underlying retinal vascular pathology stimulates the formation of perifoveal aneurysmal abnormalities.
