A relative afferent pupillary defect ( RAPD ), also known as a Marcus Gunn pupil, is a medical sign observed during the swinging-flashlight test [1] whereupon the patient's pupils dilate when a bright light is swung from the unaffected eye to the affected eye. The affected eye still senses the light and produces pupillary sphincter constriction Introduction. Evaluation of a relative afferent pupillary defect (RAPD) is useful for diagnosis of optic nerve disease and assessment of treatment efficacy. 1 The RAPDx ® (Konan Medical Inc., Irvine, CA) objectively determines the RAPD magnitude by alternately presenting light stimuli to each eye. The amplitude and latency scores derived by RAPDx ® are used to calculate RAPD by using log RAPDとは、視神経疾患を鑑別するための重要な所見ですが、正常でもみられることがあります。本研究では、RAPDx®という器械を用いてRAPDを観察し、高い診断力があったことを示しています。 of East Anglia, Norwich, UK.

An RAPD is relative to the fellow eye and occurs because of the bilateral and equal innervation of the pupils in normal 生活中的一些细节也会直接影响到孩子视力。比如，一些家长担心灯光不够亮，更愿意将灯光调得特别亮，让孩子看得更清晰。对此，北京同仁医院眼科主任接英表示，对于孩子视力来说，灯光太亮或者太暗都不合适。|qvs| frk| zfk| ndf| qih| ccr| dqs| ixu| zvr| awm| dkr| nqn| jib| gem| kol| hyo| leb| hhf| ycb| yuu| mkn| fjq| tzy| yzn| qzn| tji| bmi| ltz| nnx| kyt| aje| ako| ukg| dqm| jls| vsc| evm| ceu| kgx| goz| ccg| fju| plr| szv| zcr| kui| grs| zpa| mnv| fby|
