摘要:
The present invention relates to a scanning perimeter. The scanning perimeter comprises: - an illuminator (11) adapted to project an illumination beam (1) to illuminate the retina (101) of an eye (100); - acquisition means (27) adapted to receive light (2) reflected by the retina and to acquire images of the retina; - scanning means (17) adapted to cyclically move said illumination beam (1) on the surface of the retina, along a scanning direction (DS) and with scanning period (TS); - separation means (16) of the light beams adapted to separate said illumination beam (1) and the light (2) reflected by the retina; - a control unit (50) to control the operation of said scanning perimeter. The scanning perimeter also comprises: - first projection means (30) adapted to project a first projection beam (3) to uniformly illuminate a portion (1101) of retina (101), said first projection beam (3) passing through the pupil (102) of the eye at a second separation region (102A) between a first crossing region (102A), at which said illumination beam (1) passes through the pupil, and a second crossing region of the pupil (102B), at which the light (2) reflected by the retina passes through the pupil, during the operation of said scanning perimeter; - second projection means (41) adapted to project a second projection beam (4) to project on the retina (101) at least a fixation target, said second projection beam (4) passing through the pupil (102) of the eye at said first crossing region (102A) or said second crossing region (102B), during the operation of said scanning perimeter; - third projection means (42) adapted to project a third projection beam (5) to project on the retina (101) at least a light stimulus, said third projection beam (5) passing through the pupil (102) of the eye at said first crossing region (102A) or said second crossing region (102B), during the operation of said scanning perimeter.La présente invention concerne un périmètre à balayage.
