Abstract：
Persistent fetal vasculature is a spectrum of ocular abnormalities linked to an incomplete regression of the fetal ocular vasculature. A 21-years old male patient came to the outpatient clinic reporting low vision and strabismus in his left eye since 3 years of age. Ophtalmological examination revealed a normal right eye, while the left eye had a best corrected visual acuity of hand-motion perception, a 30 prism diopters esotropia, a \"coralliform\" cataract and a vitreous stalk joining the posterior face of the lens and the optic nerve. The coralliform cataract possessed spindle-shaped processes radiating out of its center in an axial direction and was located in the posterior subcapsular area. The patient elected to not undergo vitreoretinal surgery due to the poor visual prognosis. The unusual cataract present in the described patient could be related to his untreated status, as previous authors have reported that untreated cataracts in persistent fetal vasculature may undergo diverse degenerations.
摘要：
持续的胎儿脉管系统是一系列与胎儿眼部脉管系统的不完全消退有关的眼部异常。一名21岁的男性患者从3岁开始来到门诊，报告左眼视力低下和斜视。眼科检查显示右眼正常,而左眼的手动作知觉矫正视力最好，30棱镜屈光度内斜视，“珊瑚状”白内障和玻璃茎连接晶状体和视神经的后表面。珊瑚状白内障具有纺锤形的突起，沿轴向从其中心向外辐射，并位于后囊膜下区域。由于视力预后不良，患者选择不接受玻璃体视网膜手术。所描述的患者中存在的异常白内障可能与他的未治疗状态有关，正如以前的作者所报道的那样，在持续性胎儿脉管系统中未经治疗的白内障可能会发生不同的变性。
