Maculopatía en paciente con lupus eritematoso sistémico tratado con hidroxicloroquina

A 50-years-old woman with systemic lupus erythematosus treated for 13 years with hydroxychloroquine developed nephropathy and high blood pressure five years ago as well as moderate loss of vision in her right eye. Fundoscopy showed alterations of macular pigmentation only in the right eye. Visual fields 10-2 were normal in both eyes. Optical coherence tomography showed hyperreflective foveal thickening with a hyporreflective cavity underlying in the right macula, and was normal in left macula. Fluorescein angiography showed no bulls-eye pattern, but did show microaneurysms in vascular arcades. Multifocal central electroretinogram was diminished in right eye and the electrorretinogram pattern was diminished in both eyes. We concluded that the alterations of the right eye were suggestive of ischemic maculopathy, not hydroxychloroquine toxicity.
