Eidi Syndrome

Eidi syndrome - a special form of lesion of the innervation of the pupil (internal ophthalmoplegia) in the form of a unilateral mydriasis with loss of pupillary reaction to light and puchillotonia.

Etiology, pathogenesis. The cause of the disease is unknown. Defeat of the ciliary knot located in the orbit.

Symptoms, course. Osteoporosis, sometimes after a headache, develops a unilateral mydriasis and visual impairment due to paralysis of accommodation. The extended pupil does not respond to light, but it narrows sharply when convergence. As a narrowing, and especially the subsequent expansion of the pupil is very slow (puchillotonia). Muscles of the affected pupil are hypersensitive to mystical means. In 60% of cases, the pathology of the pupil is combined with the loss of tendon reflexes on the legs. Occasionally a few months or years later the second pupil is affected. The disease is observed mainly in women.

Of extreme importance is the formal similarity (dissociated impairment of pupillary reactions) of the syndrome of Adi with Argyll Robertson syndrome, characteristic of neurosyphilis. As a rule, Argyle Robertson's syndrome is bilateral, and most importantly, there is no phenomenon of papillotonia with it.

Treatment is not developed.

Forecast. Mydriasis is persistent, but in some cases it is possible to soften the symptoms.
