[Case report of Möbius syndrome]

The authors describe a 5-year-old girl with congenital unilateral paralysis of the oculomotor nerve and bilateral paralysis of the facial nerve. Additionally, there was a strange innervation anomaly, which manifested as paradoxical movements of the lids in horizontal gaze movements. The case is considered to be a form of oculofacial paralysis and the findings are compared to those published in the literature.
