title: [The "synoptometer" as basis for surgical indication and postoperative follow-up study in cases with complicated extraocular muscle diseases (author's transl)].
abstract: Determinating the objective angle of squint with the usual diagnosis procedures false results are not uncommon. On the other hand muscle-function cannot be estimated in the extreme direction of gaze because of interference with the patient's nose and orbital margin. The newly developed "Synoptometer" (Oculus-Dutenhofen, W-Germany) provides the possibilities of determination the objective angle of squint in the extreme direction of gaze; false results can be prevented. This new instrument offers wide range of diagnostic possibilities for the evaluation of extraocular muscle paresis and for surgical indications; typical cases are demonstrated.
