儿童经常眯眼看东西警惕白内障!

白内障是任何年龄阶段的人都会患上的,小孩子也会患白内障,但是大部分的白内障多发生于50岁以上的中老年人身上,年龄相关性的白内障是随着人的年龄增大,人体各功能下降所造成的眼睛晶状体变浑浊的一种表现,但这并不代表青年人和儿童便与此无关。儿童白内障通常包含先天性白内障、外伤性白内障等,是一种较为严重的致盲疾病,严重影响儿童的视力发育,属于难愈性弱视。

 孩子眯眼、侧头很可能是白内障!

 白内障不仅仅和老年人联系在一起,其实,小孩子如果经常眯眼睛,也可能是患上了白内障。家长一定要细心观察孩子的眼睛发育情况,若发现孩子经常看电视习惯走到电视前,经常眨眼睛、揉眼睛、眯眼或侧着头看东西,请务必带孩子到医院检查,以确定是否有视力损伤情况。尤其是有眼病家族史的孩子,要经常留意孩子瞳孔区的变化。正常的孩子双眼角膜和晶状体是透明的,且两侧瞳孔等大正圆,对光反应灵敏。若家长发现孩子瞳孔区变白或灰暗无光泽,应警惕先天性白内障的存在,及早去正规医院检查。

 母亲孕期病毒感染 也会致孩子白内障

 先天性白内障的病因主要是由于胎儿在发育过程中晶状体生长发生障碍的结果,其原因有内源性和外源性两种。内源性与染色体基因有关,属遗传性,有家族史。而外源性是由母体在妊娠的前3个月感染所致。如风疹、水痘、单纯疱疹、麻疹、带状疱疹及流感等病毒,或是怀孕期营养代谢一时失调造成的胎儿晶状体混浊。如果,孕妇在孕期受到有毒物质、射线的侵害,也会增大新生儿患上白内障的风险。

 早发现不容易,医生建议新生儿都做眼疾筛查

 先天性白内障可以发生在双眼,也可以发生在单眼。有的孩子单眼斜视,家长一定要留意,看是不是弱视的那只眼有先天性白内障等眼疾,因为斜视可能是因一眼看不到而偏斜。

 先天性白内障不红、不痛、不痒,只是影响视力,很多先天性白内障没有被及早发现,导致孩子视力发育受影响。之所以不易被发现,是因为孩子瞳孔偏小,位于瞳孔后方的晶体即使浑浊了,也几乎不可能通过瞳孔观察到,只有散瞳后才能发现。很多家长,是发现孩子见光没反应,孩子七八个月甚至1岁后才发现。

 建议所有新生儿出生后应尽早进行眼疾筛查或早产儿筛查,包括眼科的筛查。早产儿眼科筛查尤为必要,除了可发现先天性白内障,还可发现与早产氧箱治疗相关的视网膜病,这些眼病均可导致孩子视力受损。

 白内障似遮挡眼睛的“窗帘” 5岁前不摘恐失明

 6岁以前是视力发育期,白内障如同遮住眼睛的窗帘,光线照不到眼睛里,就无法刺激视力的正常发育,如果6岁以前“窗帘”不能及时摘掉,就会造成斜视、弱视,甚至永久性失明等严重后果。

 如果发现患儿患有白内障,就应该及早采取正确治疗,对于先天性白内障如符合手术条件的应尽早手术。在小儿能耐受麻醉时即可手术,因儿童眼球正处于生长发育时期,一旦错过手术好治疗时机,将会造成永久性不良后果。手术太晚可造成弱视。另外儿童正处于生长发育旺盛时期,晶状体上皮细胞增生活跃。术后后发障明显高于成人,发生率大约75%~100%。这也是为什么有些儿童作了白内障手术经过一段时间视力又下降了,所以儿童白内障术后应定期到医院复查。
