  • 简介:目的:对一个染色体显性遗传的先天性脉络膜缺损家系进行ABCB6基因的突变筛查,明确致病基因。方法:近来报道ABCB6基因突变可导致先天性脉络膜缺损,我们搜集了一个中国汉族先天性脉络膜缺损家系,采集家系成员及一百位正常对照人群的静脉血5mL,使用PCR产物直接测序对ABCB6基因进行突变筛查。结果:在该家系中我们发现了一个新突变(c.1380c〉a),该突变在家系中与疾病表型共分离,并且在100名正常对照中均未发现该突变。结论:我们的研究结果扩大了ABCB6基因的突变谱,进一步确认了该基因在眼组织缺损发病中发挥了重要作用。

  • 简介:晶状体眼植入后房型人工晶状体是矫正屈光不正的有效方法,植入的后房型人工晶状体目前主要有可植入式接触镜(implantablecontactlens,ICL)和晶状体眼屈光性晶状体(phakicrefractivelens,PRL)。对术后患者主观视觉质量(视力、对比敏感度)、客观视觉质量(波前像差、点扩散函数、斯特尔比率及光学传递函数)的研究显示,主观视力的提高也伴随着客观视觉质量的改善,但部分患者术后出现光晕及眩光症状。本文主要对ICL和PRL植入术后主观及客观视觉质量的临床研究做一综述,对可影响视觉质量的术后并发症如晶状体前囊膜下混浊、青光眼及角膜内皮功能异常等需进一步远期随访。
