A combined apparatus for measuring the blood glucose level from an ocular fluid comprises a hand-held fluorescence photometer (D 1 ) for determining the glucose level of the ocular fluid and a device (D 2 ) for the amperometric or photometric determination of the blood glucose level. The fluorescence photometer (D 1 ) comprises: first irradiating means ( 7,8,10 ) for providing a pilot beam ( 1 ) for irradiation of the eye ( 3 ) in order to excite a first fluorescence comprising a first wavelength band; first detecting means ( 8,9,12,13 ) for measuring the intensity of the of the pupil fluorescence within the first wavelength band; second irradiating means ( 17,18,21 ) for providing a measurement beam ( 5 ) for irradiation of the eye in order to excite an ocular sensor ( 4 ) to emit a second fluorescence comprising a second wavelength band; second detecting means ( 18,19,20,22,23,24,25 ) for measuring the intensity of the second fluorescence within the second wavelength band. The first and second irradiating means are arranged such that the measurement beam irradiates the eye under a predetermined angle (a) between 0° and 90° and at a predetermined distance from the pilot beam.
