A method and system are proposed for imaging the retinal structure of an eye. A light source is provided and a repetitive pattern is projected on the retina by said hght source having illuminated and non-illuminated portions with a spatial frequency larger than 0.5 mm-1. For the illuminated and non-illuminated portions a fluorescence level is measured; and a fluorescence level is derived as a corrected value for illuminated and non-illuminated areas.
