Abstract

Microperimetry and examinations of the front and back of the eye are made possible by the ophthalmologic examination instrument. The ophthalmologic examination instrument with at least one illumination arrangement for generating temporally and spatially variable light marks and/or luminous fields has an input unit for adjusting the illumination conditions, a signaling device for reporting the detectability and/or undetectability of the light marks, an output unit, and a control unit. In the method, a light mark for fixating the patient's eye and a movable light mark which is variable with respect to position, shape, brightness and/or color is projected in sequence on the back of the eye. Conclusions can be made about the vision of the patient from the detectability of the light marks on the part of the patient. Based on its varied possibilities for producing and manipulating light marks and/or luminous fields, the suggested solution offers an extremely broad applicability in eye examinations. It is possible to locate spatially small functional disturbances on the back of the eye in a fast and reliable manner through monitored microperimetry while simultaneously observing the fundus and with the participation of the subject.
