摘要

中央凹新生血管(FNV)是一种罕见的临床发现的条件下,血管妥协,导致视网膜缺血。我们报告一例伴有FNV的增殖性糖尿病视网膜病变(PDR),其光学相干断层血管造影(OCTA)证实了中央凹出血样团块的结构、范围、活动性和来源。数字荧光素血管造影(DFA)显示双眼PDR,但右眼中央凹渗漏部位未见视网膜内微血管异常(IrMAs)或FNV。OCTA证实FNV突破内限制膜(ILM),突入玻璃体,并确定其起源于浅血管丛(SVC)。此外,分割显示脉络膜毛细血管板有血流空洞,提示脉络膜缺血。

Foveal neovascularization in proliferative diabetic retinopathy: Characterization with OCTA
Foveal neovascularization (FNV) is a rare clinical finding in conditions with vascular compromise, leading to ischemia of the retina. We present a case of proliferative diabetic retinopathy (PDR) with FNV, where optical coherence tomography angiography (OCTA) confirmed the architecture, extent, activity, and origin of a hemorrhage-like clump at the fovea. Digital Florescein Angiography (DFA) showed PDR (both eyes), but intra-retina microvascular abnormalities (IrMAs) or FNV could not be differentiated at the site of leak in right eye fovea. OCTA confirmed a FNV breaching the internal limiting membrane (ILM), protruding into vitreous, and determined its origin from superficial vascular plexus (SVC). Also, segmentation revealed flow voids in choriocapillaris slab, suggesting choroidal ischemia.
