[A new instrument for measuring eyelid strength].
Former investigations concerning muscular eyelid strength with dynamic registration revealed great inter- and intraindividual variations. We tried to minimize these influences by using an electronic power register with isometric registration. This is important because lid closing is a complex mechanism of horizontal and vertical movements with continuously changing power vectors. Our new apparatus reduces false results. A normal collective of 114 persons was examined. The results show no statistically significant age- or sex-related differences in lid strength.
