共同性内斜视手术后的立体视觉

Stereovision of Concomitant Esotropia After Operation

【目的】探讨共同性内斜视对立体视觉的影响。【方法】观察48例共同性内斜视患者手术后的远近立体视情况,比较不同发病年龄和手术年龄对立体视的影响。【结果】内斜视术后立体视与术前有显著性差异,发病年龄越小,手术年龄越大立体视恢复越差,内斜视患者术后近立体视仍明显较正常儿童差。【结论】共同性内斜视严重影响立体视觉的发育,早期手术可提高功能治愈率。

[Objective] To investigate the influence of concomitant esotropia on stereovision. [Methods] The stereoscopic vision in 48 concomitant esotropia patients after operation was observed. The influence of age of onset and operative age on stereovision was compared. [Results]The difference in stereovision between pre and post operation was significant. The age of onset and operative age were significantly correlated to the postoperative stereovision. The stereovision in patients with the younger age of onset and older operative age was poorer. And the stereovision of esotropia patients after operation was poorer than that in normal controls. [Conclusion]The esotropia has an important influence in the development of stereovision. The early correction of eve oosition will benefit the restoration of stereovision and the achievement of functional cure.
