Colorectal cancer （CRC） is one of the most common neoplasms and an important cause of mortality worldwide （http：//globocan. ***]）. Approximately 35% of the variation in CRC susceptibility is likely due to heritable factors （Lichtenstein et al., 2000}. Genetic variations in the human genome include single nucleotide variants （SNVs）, short insertions and deletions, and larger structural variants resulting in gain or loss of genomic DNA larger than 1 kb, such as copy number variants （CNVs）. Leaving aside the importance of CNVs in sporadic tumor development, these variants can also be present in the germline DNA of healthy individuals from the general population and be considered polymorphic.

目的:分析西班牙某三级医院视网膜科接受手术治疗的黄斑裂孔性视网膜脱离患者。着重强调诊断与手术之间的时间间隔,试图寻找术前时间与视力下降之间的关系。方法:回顾性研究。包括77例在Universitario Fundación Jiménez Díaz医院接受手术治疗的黄斑裂孔性视网膜脱离患者。结果:77例患者中有72例(72眼)参与了该研究。初步手术成功率为94.44%(68/72),采取1或2次干预措施后,全部患者成功率为98.61%(71/72)。术前平均时间为5.3±2.26d。7(9.72%)例患者视力下降2行或更多。视力下降与患者年龄之间具有统计学意义(P=0.001)。研究表明进一步手术干预使视网膜再次附着与视力下降检测之间存在相关联系(P=0.045)。而研究未能发现视力下降与术前时间(P=0.100),手术类型(P=0.578)或晶状体状态(P=0.413)之间具有统计学意义。结论:每家医院都应该研究治疗此类型视网膜脱离治疗的方式,以优化利用现有资源,确保最佳的解剖结构复位和功能恢复。
