This risk is minimal if the retinopathy was detected early, but significant if there is already a bull's-eye lesion and some reduction in central foveal thickness, because damage can progress for a number of years. In HCQ-induced retinopathy, FAF images show early hyper-autofluorescent parafoveal ring corresponding to photoreceptor damage, which decreases in signal strength over time due to RPE atrophy (hypoautofluorescent). Structurally, this initially appears as mottling of the RPE pigment and with prolonged use becomes concentric rings of hypo- and hyper-pigmentation, giving a 'bull's eye' target appearance.
