One device, be used in the multiple sessions for being time interval respectively monitor a patient eyes one or more parameters and the eyes of patient can move in-between, including this device:For taking a video camera of one or more images of eyes； For illuminating eyes by a cyclic annular optical mode to generate a lighting unit of corneal reflection, the lighting unit is preferably located, so that the light shaft coaxle at the center of ring and video camera； One component is used to determine the position of the corneal reflection according to eyes image in the first ession for telecommunication； One component, it is used for first session in the determining position based on corneal reflection, determines based on using eyes as during at least one other parameter of eyes and its coordinate in the first coordinate system of a geometrical model of a spherical eyeball of the cornea shaped with having the ball of installation there； One component is used to determine in the second ession for telecommunication temporarily separated with position described in first session of the corneal reflection of the other eye parameters and its coordinate in the eyes in second of coordinate system and on its basis； One component for determine eye motion in six degree of freedom between described first andSecond session and for determine on its basis coordinate conversion； One component is used to be converted other eye parameters and its coordinate from first coordinate system based on the eye motion of the determination and enters second coordinate system； Parameter measure in first ession for telecommunication for the component in the variation of its coordinate between quantifying and/or visualize the other eye parameters of first and second session based on the other parameter in second ession for telecommunication measurement and the transformation and its coordinate.Zamansal olarak birbirlerinden ayrı olan ve aralarında hastanın hareket edebile
