Abstract
The invention relates, according to one aspect, to a retinal imaging device including at least one source (LSa, LSr) for emitting a light beam in order to illuminate the retina of an eye (10) of a subject, a retinal imaging path including a detection device (12) having a detection plane (121) and an optical imaging system (L1, L5, L6), an analysis path including a device (15) for measuring optical defects having an analysis plane (151) for receiving a set of light rays backscattered by the retina and optical means for adjoining said analysis plane and a predetermined plane in the input space of said imaging system of the imaging path, a correction device (14) shared by said analysis and imaging paths, which includes a correction plane (141) and which is intended to correct, in said correction plane, the light rays from said emission source and backscattered by the retina according to the optical defects measured by the device for measuring optical defects. The retinal imaging device further includes a light blackout system (20), which is positioned in an adjacent plane or which coincides with said correction plane, or which is positioned in an image plane of said correction plane l…
