Hydroxychloroquine retinopathy causes destruction of macular rods and cones with sparing of foveal cones. This pattern provides the typical bullseye appearance. RPE migrates into the areas of destructed photoreceptors, causing pigment laden cells to be detected in the outer nuclear and outer plexiform layers 1.
