    摘要: A method is disclosed for fixing at least one location in an examination field (9) with respect to a coordinate system (13). The method includes determining, in response to a request (65), coordinates of a first location (59) as a first coordinate set (x, y, z) allocated to the first location (59). A first recording and a second recording of topological data (69) in a spatially extended area around the first location (59) in the examination field (9) are obtained. The first and second recordings are compared to determine a displacement (&Dgr;x, &Dgr;y, &Dgr;z) of the first location (59) of the examination field (9) with respect to the coordinate system (13), the coordinates of the first coordinate set (x, y, z) allocated to the first location (59) are changed dependent upon the determined displacement (&Dgr;x, &Dgr;y, &Dgr;z) such that the changed coordinates substantially correspond to the coordinates of the first location (59) in the examination field (9) after the displacement thereof.

    摘要: Systems and methods are described for imaging an eye portion or for treating glaucoma in an eye of a patient. In a first step an optical microscopic image of a portion of the eye is acquired. In the optical microscopic image a distinguishable anatomical structure is identified to predict a location of a volume portion to be imaged three-dimensionally. Three-dimensional imaging of the located volume portion is performed by acquiring an optical coherence tomography image of the located volume portion. The volume portion is treated by either directing a laser beam to the volume portion or inserting an implant based on the OCT-image.
