A system for measuring ocular motility of a patient comprising: a head tracker configured for detecting head tracking data comprising at least one of head location, direction and movement to thereby enable determining ocular motility parameters for different gazing directions; a display unit capable of alternatively presenting two targets, one for each eye of the patient; a blocking unit configured and operable to selectively block/unblock a field of view of at least one eye of the patient; a camera unit comprising at least one imaging element configured and operable to generate at least two image data indicative of at least one eye condition; and; a processing unit connected to the head tracker , to the blocking unit , to the display unit and to the camera unit , said processing unit being configured for performing the following steps:(a) displaying two targets, one for each eye; (b) receiving image data indicative of at least one eye's condition from said camera unit and said head tracker data from said head tracker, (c) controlling the blocking unit to block/unblock at least one target in the field of view of an eye of the patient, (d) detecting a change in at least one eye's condition as a result of said blocking / unblocking, (e) displacing the target for at least one eye and repeating steps (a)-(e) until no change in the eye's condition is measured to thereby determine at least one ocular motility parameter. a head tracker configured for detecting head tracking data comprising at least one of head location, direction and movement to thereby enable determining ocular motility parameters for different gazing directions; a display unit capable of alternatively presenting two targets, one for each eye of the patient; a blocking unit configured and operable to selectively block/unblock a field of view of at least one eye of the patient; a camera unit comprising at least one imaging element configured and operable to generate at least two image data indicative of at least one eye condition; and; a processing unit connected to the head tracker , to the blocking unit , to the display unit and to the camera unit , said processing unit being configured for performing the following steps:(a) displaying two targets, one for each eye; (b) receiving image data indicative of at least one eye's condition from said camera unit and said head tracker data from said head tracker, (c) controlling the blocking unit to block/unblock at least one target in the field of view of an eye of the patient, (d) detecting a change in at least one eye's condition as a result of said blocking / unblocking, (e) displacing the target for at least one eye and repeating steps (a)-(e) until no change in the eye's condition is measured to thereby determine at least one ocular motility parameter.
