A system for imaging an ocular fundus semi-automatically at high resolution and wide field

摘要

A system for obtaining images of the fundus of an eye includes an illumination device which directs a light beam onto a portion of the fundus of the eye, and a video camera which records the portion of the light reflected from the fundus of the eye. The pupil of the eye is automatically centered and brought into focus, and the fundus of the eye is then automatically brought into focus. A plurality of target images are presented at different locations in space so that the eye will move when focusing on these different locations. As the eye moves, different areas of the fundus are illuminated, and images of these different areas of the fundus are recorded by the video camera. The plurality of images from the different areas of the fundus are then automatically arranged by a computer in a mosaic image representative of a section of the fundus including the plurality of areas. Data representative of the mosaic image is transmitted to a remote site for analysis. Additionally, the system can perform visual acuity and perimetry testing on the eye whose fundus is being imaged.
