Synkinesis results from nerve miswirings and causes aberrant movements of the affected muscles. We present a series of cases of rare congenital ocular synkinesis involving the extraocular muscles and the levator palpebrae superioris and speculate the possibility of classifying these entities in the spectrum of congenital cranial dysinnervation disorder.
Records of patients with the diagnosis of congenital ocular synkinesis were analyzed retrospectively. We analyzed the sex, laterality, and complete features of the ocular motility of each patient.
Nine patients with congenital ocular synkinesis were included. A slight predominance of women was noted. In terms of laterality, four patients had only the right eye involved, four had only the left eye, and one had both eyes involved. Notably, 55.5% were orthotropic in the primary position. The third, fourth, and sixth cranial nerves were involved in the miswiring in 100%, 44.4%, and 11.1% of the cases, respectively.
Congenital synkinesis might present in a very eclectic and uncommon fashion. The aberrant innervation in these cases classifies them into the group of congenital cranial dysinnervation disorders.
联带运动是由神经错配引起的，导致受影响肌肉的异常运动。我们报告了一系列罕见的先天性眼肌联带运动的病例，涉及眼外肌和上睑提肌，并推测这些疾病可能属于先天性颅神经发育障碍的范畴。
回顾性分析诊断为先天性眼肌联带运动的患者的病历。我们分析了每位患者的性别、偏侧性和眼球运动的完整特征。
共纳入 9 例先天性眼肌联带运动患者。女性略占优势。就偏侧性而言，4 例仅右眼受累，4 例仅左眼受累，1 例双眼受累。值得注意的是，55.5%的患者在第一眼位为正位。第三、四、六对颅神经在受累病例中分别占 100%、44.4%和 11.1%。
先天性联带运动可能表现出非常独特和不常见的方式。这些病例中的异常神经支配将其归类为先天性颅神经发育障碍疾病。
