Pattern of Retinopathy: Although the locus of toxic damage is parafoveal in many eyes, Asian patients often show an extramacular pattern of damage. Dose: We recommend a maximum daily HCQ use of 5.0 mg/kg real weight, which correlates better with risk than ideal weight.

Several factors have been associated with the risk of developing hydroxychloroquine retinopathy. One of the most important appears to be dosage—with debate over whether daily intake vs. cumulative dosage is most. In 2011, guidelines warned about toxicity risk at a cumulative dose of 1000 g or exceeding 6.5 mg/kg body weight/day. For a typical patient, most would reach the cumulative dose at 200 mg bid in 5 years. 2 It is rare for vision changes to occur. The AAO guidelines defined high-risk patients by any one of the following criteria HCQ treatment 5 years in duration, HCQ dose 6.5 mg/kg/day, significant renal or hepatic disease, preexisting maculopathy due to other etiology, age 60 years, obesity, or cumulative HCQ consumption of 1000 g. Risk of Toxicity: The risk of toxicity is dependent on daily dose and duration of use. There are no similar demographic data for CQ, but dose comparisons in older literature suggest using 2.3 mg/kg real weight.

The following adverse reactions have been identified during post-approval use of PLAQUENIL or other 4-aminoqunoline compounds. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. Another study of 4000 patients found a prevalence of 6.8/1000 patients 8. Risk factors that increase the chance of hydroxychloroquine retinopathy include daily dosage, cumulative dose, renal or liver disease, age, and previous retinal disease 9.
