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.

The risk of toxic retinopathy in patients on long-term hydroxychloroquine therapy. Risk Factors. Hydroxychloroquine retinopathy is most influenced by daily dose and duration of use. Risk for toxicity is less with 5.0 mg/kg real weight/day for hydroxychloroquine and 2.3 mg/kg real weight/day for chloroquine. Patients are at low risk during the first 5 years of treatment. There are risk factors which may increase the likelihood of an individual in developing symptoms of Plaquenil toxicity 1. Dosage The amount of drug the patient takes play a big role in increasing the risk for toxicity. 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.

Remember, any patient who is at a high risk for Plaquenil toxicity should be examined on an annual basis following the baseline exam. The goal of monitoring/screening is to identify early macular damage prior to irreversible vision loss or even before visible signs of bull’s eye maculopathy. Major Risk Factors High dose and long duration of use are the most significant risks. Other major factors are concomitant renal disease, or use of tamoxifen. Screening Schedule A baseline fundus examination should be performed to rule out preexisting maculopathy. Background The American Academy of Ophthalmology recommendations on screening for chloroquine CQ and hydroxychloroquine HCQ retinopathy are revised in light of new information about the prevalence of toxicity, risk factors, fundus distribution, and effectiveness of screening tools.
