[Hereditary crossed palpebro-palpebral synkinesia].

The author describes 3 variants of involuntary -- synkinetic movements of the eyelid seen in 36 among the 250 examined patients. A study of the genealogy demonstrated a hereditary nature of this abnormality. In most of the cases the inheritance was of the auto-some-dominant type. Inasmuch as there is a regular combination of hereditary crossed palpebro-palpebral synkinesis with inborn signs of stem structure insufficiency the importance of such synkinesis for the differentiation of inborn and acquired microorganic symptomatology is stressed.
