[Levator strenght measurements. Oculomyodynamometry of the levator palpebrae superioris (author's transl)].
The author describes a method of levator strength measurement with the oculomyodynamometer with which he measured a maximum strength of the levator muscle in adults of 58 G. The levators were much weaker in congenital ptosis. In three such cases the levators had strengths of only 9 G, 5 G and 5 G. In cases of acquired ptosis the reduced strength of the levators was on an average about half normal. This method allows 1. better diagnosis with levator paresis, 2. a control of its behaviour during the clinical course, 3. profiting from the measurement results for correcting operations on the levator muscle.
