Abstract: An ophthalmologic examination apparatus 1 projects a light onto a fundus oculi, detects the reflected light thereof, and forms a 3-dimensional image that represents the morphology of a retina based on the detected results. A stimulation-position specifying part 233 specifies, in the 3-dimensional image, a plurality of stimulation positions that correspond to a plurality of stimulation points Pi in a visual-field examination. A layer-thickness measuring part 235 analyzes the 3-dimensional image to find the layer thickness of the retina at each stimulation position. In addition, a displacement calculation part 234 specifies a related position of the stimulation position. A layer-thickness measuring part 235 finds the layer thickness of the retina at the related position.

Abstract: A vitreous body visualization agent which is to be injected into the eye to visualize the vitreous body by a safe and sure method. The vitreous body visualization agent is prepared by using a polymeric substance having positively or negatively charged functional groups and adding a hardly water-soluble and non-steroidal colored substance, in which the polymeric substance is to be suspended, thereto. Due to having a non-steroidal nature, it can be safely injected into the eye, and the colored substance, in which the polymeric substance is to be suspended, makes the vitreous body visually recognizable.
