The instrument is to be adapted to an ophthalmic slit-lamp (2,6) and includes holders for fluorescence excitation and barrier filters (3,5) to the light path and a detector system made of a linear array of photodiodes (8) with respective circuitry for reading and control. The light is focused in a chosen zone of the eye (13) inducing fluorescence by using specific wavelength. The fluorescence is measured by the detector (8) coupled to one of the eyepieces (12) of the slit-lamp (26) or to a beam-splitter (7) placed before the eyepieces (12). There is a system for digitalization of the signal from the detector (8) which is connected to an IBM compatible computer (11) where the data is stored and analyzed.
