PURPOSE
We report a case of relentless placoid chorioretinitis (RPC) that developed branch retinal vein occlusion and peripheral retinal neovascularization in one eye.
METHODS
A case report is presented.
RESULTS
A 33-year-old healthy man presented with decreased visual acuity (20/150) in both eyes. Slit-lamp examination revealed anterior chamber and vitreous inflammation. Multiple yellow-white lesions were evident in the macula and scattered throughout the fundus. Following workup, a diagnosis of RPC was made. The patient was started on Pred Forte (prednisolone acetate 1%) and atropine drops. Three months later, visual acuity improved to 20/70 and 20/100 in the right and left eyes, respectively. At this time, fundus examination and fluorescein angiography revealed peripheral retinal neovascularization. Sectoral scatter laser photocoagulation was performed in the areas of nonperfusion.
CONCLUSIONS
We describe a novel presentation of RPC associated with branch retinal vein occlusion and retinal neovascularization. Although the pathophysiology of RPC is believed to be primarily a choroidal vasculitis, retinal vascular changes may also occur, as observed in other white dot syndromes.
目的
我们报告一例顽固性地图状脉络膜视网膜病变（RPC），该病例一只眼睛发生了视网膜分支静脉阻塞和周边视网膜新生血管形成。
方法
呈现一例病例报告。
结果
一名33岁健康男性双眼视力下降（右眼20/150，左眼20/150）。裂隙灯检查发现前房和玻璃体炎症。黄斑区可见多个黄白色病灶，并散在分布于整个眼底。经过检查，诊断为RPC。患者开始使用百力特（1%醋酸泼尼松龙）和阿托品滴眼液。三个月后，右眼视力提高到20/70，左眼视力提高到20/100。此时，眼底检查和荧光素血管造影显示周边视网膜新生血管形成。对无灌注区域进行了扇形散射激光光凝治疗。
结论
我们描述了一例与视网膜分支静脉阻塞和视网膜新生血管形成相关的RPC新病例。尽管RPC的病理生理学被认为主要是脉络膜血管炎，但正如在其他白点综合征中所观察到的，视网膜血管变化也可能发生。
