[Diagnostic value of anesthesia for the surgery of strabismus].

There is no clinical test to detect a blockade. Under Anesthesia it is possible to discover a suspected blockade, so this test is quite helpful. Even in small babies this test can be applied in order to dected a pseudoparalysis of the external recti. We decide to operate after evaluation of the clinical facts and the findings under anesthesia according to the Zato test. We especially observe the positions of the eyes during normal breathing and the position under deep anesthesia.
