Nov 01, 2007 Thioridazine is a phenothiazine antipsychotic agent known to cause a pigmentary retinopathy. While its use in the United States has declined over the years, recent case reports still have described toxicity due to both acute 16 and long-term 17 use. The retinopathy is manifest as damage to the photoreceptors and subsequent degeneration of the retinal pigment epithelium RPE. This may produce a “Bull’s eye maculopathy” and central visual loss.
