有关脉络膜血管结构研究的进展和荧光造影的应用,对脉络膜循环障碍引起的病变,逐渐受到注意。Amalric把由于后睫状动脉闭塞引起的扇形脉络膜萎缩,称为“三角综合症”。进而有人认为回旋样视乳头周围脉络膜病变,地图样脉络膜萎缩,以及急性多发性视网膜色素上皮鳞状病变等,均与脉膜循环障碍有关。作者报告一25岁男性患者,有原发性肺动脉高压合并右心功能不全及继发红血球增多症。病史是30天来右眼视力下降,并自觉有中心暗点及视物变形。初诊时视力右0.3,左1.5。初诊所见:右眼前房和前部玻璃体有轻度的尘埃状混浊。眼底检查可见到右眼后极部有广泛的视网膜浅脱离,黄斑之颞上及鼻下方视网膜深层可见数条带状、灰白色边界不清的混浊区;从后极部至赤道部可见散在的脱色素黄白色小点及 Progress on the study of choroidal vascular structures and the application of fluorescence imaging, the choroidal circulation disorders caused by the gradual attention. Amalric refers to the choroidal atrophy caused by posterior ciliary artery occlusion, known as “trigonal syndrome.” Then some people think that the gyroid-like optic choroidal lesions around the map-like choroidal atrophy, as well as acute multiple retinal pigment epithelial squamous lesions, are associated with circulatory disorders. The authors report that a 25-year-old male patient had primary pulmonary hypertension complicated with right ventricular dysfunction and secondary polycythemia. History of 30 days to the right eye decreased vision, and consciously there are dark spots and visual distortion. The first visit visual acuity 0.3, left 1.5. First visit to see: the right anterior chamber and the front of the vitreous mild dusty cloudiness. Fundus examination can be seen in the right posterior pole has a wide range of retinal detachment, macular temporal and nasal retina deep retinal visible several bands, gray and white unclear turbid areas; from the posterior pole to the equator to see scattered Pigment yellow and white dots and
