However, the retinopathy, described as a bull’s-eye, is untreatable and tends to progress even after cessation of the drug. Accordingly, in recent years there has been an increased emphasis on more effective screening measures utilizing multimodal imaging techniques to elicit early signs of toxicity before the characteristic advanced changes manifest clinically. Best alternative to plaquenil for lupus Malaria treatment chloroquine how many daily Hydroxychloroquine hair lightening Plaquenil and muscle weakness Fundus changes on biomicroscopy, including bull's eye maculopathy, are indicative of fairly advanced hydroxychloroquine-induced retinal toxicity which is largely irreversible despite cessation of the medication. The American Academy of Ophthalmology has published several dosing and screening recommendations for hydroxychloroquine to avoid potential retinal toxicity, yet some patients still experience permanent vision loss resulting from hydroxychloroquine retinopathy due to improper dosing of the drug and improper screening. The American Academy of Ophthalmology released an updated set of screening recommendations for hydroxychloroquine Plaquenil and chloroquine to account for the many studies that have shown the effects of these medications on the retina 1. It succinctly makes the case for screening, and In the earliest stages of HCQ toxicity, patients are often asymptomatic with preservation of visual acuity. This review summarizes the clinical presentation of HCQ retinopathy, current American Academy of Ophthalmology recommended screening guidelines and contribution of ancillary imaging studies in establishing a timely diagnosis.

Previously described OCT findings in HCQ toxicity include loss of the external limiting membrane, disruption of the outer ellipsoid zone.
