摘要先天性内斜视是在生后6个月内出现的内斜视,由于其发病早且常为恒定性,对双眼视功能的损害相比其他类型的斜视更严重,通常需要手术干预.早期手术有利于建立和改善双眼视功能,却很难在术前获得可靠、准确的测量,有可能增加二次手术和麻醉等风险；晚期手术时斜视角度测量结果虽更可靠,但降低了恢复双眼视的可能性,且长时间内斜视导致内直肌挛缩增加了眼球外转的机械性限制因素.因此,何时为先天性内斜视的最佳手术时机一直是该专业内不断争议的热点话题.本文结合临床实际及目前研究现状,围绕上述问题展开讨论并提出观点,以期引起同道的关注与讨论.

abstractsCongenital esotropia is defined as an esotropia before the age of 6 months,because of its early onset and often constant angle,it cause heavier binocular visual function damage compared with other types of strabismus.Early surgery can improve binocular visual function,but demand reliable,accurate measurements which is difficult to achieve in children,and it may increase the risk of second surgery,amblyopia and anesthesia.Late surgery can gain reliable strabismus angle,but it reduced the likelihood of recovery binocular visual function,and the contracture of medial rectus after a long time esotropia increased mechanical limitation of adduction.Therefore,the choice of timing to do surgery has been controversy over the years.In this paper,we will combine the research status and clinical practice to discuss this issue,and present some point of view for the peer reference.
