Provided is an ocular function inspection device having no risk of increasing the cost of optical systems and also having no risk of measurement errors being caused by using, as a display device, a device such as a liquid crystal display device having a slow response speed. The ocular function measurement device is characterized by comprising: a visual target display device an optical system for transmitting an image displayed on the visual target display device, to the retina in the eye of a subject a reflection optical member arranged upon the optical axis of the optical system, having the rotation center thereof positioned at a position optically conjugated with the eyeball center of the subject, and configured so as to be rotatable around the rotation center thereof an eyeball observation device that detects movement of the eye of the subject, by detecting changes in the retinal image of the subject and/or changes in the pupil of the subject and a reflection optical member control device that, by synchronizing with the eyeball movement detected by the eyeball observation device and rotating and controlling the reflection optical member, performs control whereby the optical axis of the optical system is corrected and the section where the visual target is presented on the retina, when the subject is closely observing a prescribed visual target, is set regardless of the movement of the eyeball.La présente invention concerne un dispositif dinspection de fonction oculaire qui ne présente aucun risque daugmenter le coût des systèmes optiques et qui ne présente également aucun risque de provoquer des erreurs de mesure par lutilisation, comme dispositif daffichage, dun dispositif tel quun dispositif daffichage à cristaux liquides ayant une faible vitesse de réponse. Le dispositif de mesure de la fonction oculaire est caractérisé en ce quil comprend : un dispositif daffichage de cible visuelle un système optique destiné à transmettre une image affichée sur le dispositi
