背景稠密的先天的奔流经常引起严重视觉缺陷。在中国的稠密的双边的先天的奔流的长期的后续的结果很好没被记录。这研究的目的是在在在孙中山大学的眼的中心逆动地是的中山经历了在1992年1月和2000年12月之间的稠密的双边的先天的奔流的外科的孩子的 China.Methods 医药记录的南部的部分为稠密的双边的先天的奔流经历了奔流抽取的孩子评估长期的视觉功能考察。在为当前的后续可得到的 38 个孩子，最好的改正的视觉尖酸(BCVA ) 和实体镜的视觉，以及眼球震颤，斜视，和另外的复杂并发症，被评估。吝啬的后续时期是 107.6 个月(范围 60 ～ 167 月) 奔流抽取和第二等的 intraocular 透镜培植的吝啬的年龄是的 .Results 5.6 个月(范围 3 ～ 12 月) 和 4.2 年(范围 2.4 ～ 15 年) 分别地。吝啬的 BCVA 在更好的眼睛是 0.25， 0.16 在家伙看。实体镜的视觉在所有病人是不在的，并且 3 个孩子有同时的感觉。眼球震颤在 35 种情况中在所有情况和斜视中被检测。高关联在奔流抽取和更好的眼睛的最后的 BCVA 预定之间被发现(r=-0.55， P=0.00 ) 。统计上重要的差别在在弱视的 postand 预告的处理之间的 BCVA 被发现的 A (t=5.65， P=0.00 ).Conclusions 当奔流外科在 3 个月的年龄被执行时，在有稠密的双边的先天的奔流的孩子的长期的视觉功能是差的或以后。有足够的光康复的更早的奔流外科贡献了更好视觉的结果。

英文摘要：

Background Dense congenital cataracts often cause severe visual impairment. The results of long-term follow-up of dense bilateral congenital cataract in China have not been well documented. The purpose of this study was to evaluate the long-term visual function in children who underwent cataract extraction for dense bilateral congenital cataract in southern part of China. Methods Medical records of children who underwent surgery of dense bilateral congenital cataract between January 1992 and December 2000 at Zhongshan Ophthalmic Center of Sun Yat-sen University were retroactively reviewed. In 38 children available for current follow-up, best corrected visual acuity （BCVA） and stereoscopic vision, as well as nystagmus, strabismus, and other complications, were evaluated. The mean follow-up period was 107.6 months （range 60 to 167 months）. Results The mean age of cataract extraction and secondary intraocular lens implantation were 5.6 months （range 3 to 12 months） and 4.2 years （range 2.4 to 15 years）, respectively. The mean BCVA was 0.25 in the better eye and 0.16 in the fellow eye. Stereoscopic vision was absent in all patients, and 3 children had simultaneous perception. Nystagmus was detected in all cases and strabismus in 35 cases. A high correlation was found between timing of cataract extraction and final BCVA of the better eye （r=-0.55, P=0.00）. A statistically significant difference was found in BCVA between post- and pre-treatment of amblyopia （t=5.65, P=0.00）. Conclusions Long-term visual function in children with dense bilateral congenital cataract was poor when cataract surgery was performed at age of 3 months or later. Earlier cataract surgery with adequate optical rehabilitation contributed to better visual outcome.
