They are related drugs with different therapeutic and toxic doses with similar clinical indications for use and manifestations of retinal toxicity. SD-OCT is an objective test for toxicity that complements 10-2 visual field testing. 10-2 visual testing is probably more sensitive, but is heir to interpretational difficulties and variability not so much a problem with SD-OCT. Several risk factors may increase the likelihood of retinal toxicity from Plaquenil such as, age of greater than 60 years, daily dose more than 6.5 mg/kg; use of the drug more than 5 years, obesity, preexisting retinal disease and, renal or liver failure.

Conclusions Once HCQ retinopathy is diagnosed and the medication is discontinued, structural retinal changes commonly occur. Although hydroxychloroquine retinal toxicity is thought to be rare, recent studies suggest it may have a higher prevalence than previously recognized. A large study examining patients with more than 5 years of HCQ use were evaluated with 10-2 visual fields or spectral-domain optical coherence tomography SD OCT.
