An analysis method for determining a morphological property of an optic disc and/or a retinal nerve fiber layer of an eye is, performed an ophthalmological device, in particular a perimeter, and also means for data processing using a database with functional data of a field of vision and morphological data of the optic disc and/or retinal nerve fiber layer, wherein, by the ophthalmological device, functional data of a field of vision of the eye are measured, a retina being divided into points representing the field of vision, optical stimuli of a defined intensity being provided to the points of the retina, a reaction to a stimulus being determined as a measuring result of a point, the measuring results having a statistically significant relation to morphological data of the optic disc and/or the retinal nerve fiber layer, the morphological data nerve fiber layer being derived from the measuring results and the datasets.
An analysis method for determining a morphological property of a retinal nerve fiber layer of an eye, whereby the analysis method is performed by means of a perimeter (16), and also means for data processing (17) using a database (19), the database comprises a plurality of datasets of healthy eyes and datasets of eyes with glaucoma, each of the datasets comprises functional data of a field of vision obtained by perimetric measurements and morphological data of a retinal nerve fiber layer obtained by OCT measurements, wherein, by means of the perimeter, functional data of a field of vision of the eye are measured, a retina of the eye being divided into points (23), which represent the field of vision, optical stimuli of a defined intensity being provided to predetermined points (P1, P22, P26, P35, P44, P57) of the retina which are selected from the database, a reaction to a stimulus being determined as a measuring result of a predetermined point, the measuring results of the predetermined points having a statistically significant relation to morphological data of a retinal nerve fiber layer of the eye, the morphological data of the retinal nerve fiber layer of the eye being derived from the measuring results of the predetermined points and from the datasets.
