    Optical instrument for the measurement of macular pigment density in the eye and associated method. The instrument includes: - a light source (500), - several lenses l1, l2, l3 located between the light source and the eye to be studied, - a diaphragm d1 conjugated in the plane of the pupil of the eye to be studied to allow control of the position of light input in the eye, - a photodetector (520), - a mirror m1 that directs the exit light of the eye towards the photodetector (520), - a diaphragm d2 conjugated in the plane of the pupil of the eye, which determines the path of exit of the light coming from the fundus of the eye, - at least one lens l4 between the diaphragm d2 and the photodetector (520), And the light source (500) comprises a central part (501) and a peripheral part (502), the light source (500) being modulated in four different frequencies corresponding to the green light in the central part, the green light in the peripheral part, the blue light in the central part and the blue light in the peripheral part, the light source (500) projecting on the fundus, so that the central part (501) of the light source (500) ) is projected onto the macula of the eye, and so that the fundus response signal is received in the photodetector (520).
