If the complete baseline exam is normal and the patient is at low risk for hydroxychloroquine retinopathy, then follow the recommended screening interval Perform a complete eye examination, including a dilated fundus exam. Hydroxychloroquine HCQ retinopathy can result in permanent vision loss. In early stages of HCQ retinopathy, patients are usually asymptomatic with preservation of visual acuity. We aspire that our review, in conjunction with the American Academy of. Study researchers concluded that hydroxychloroquine blood level testing may effectively predict the risk for retinopathy, and give clinicians an insight as to whether to decrease hydroxychloroquine dose or increase monitoring in patients with high hydroxychloroquine blood levels. Reference. Petri M, Elkhalifa M, Li J, Magder LS, Goldman DW. Dose: We recommend a maximum daily HCQ use of 5.0 mg/kg real weight, which correlates better with risk than ideal weight.

Further, an atypical pattern of retinopathy called pericentral retinopathy is more common in Asians. A study of about 200 patients with a history of hydroxychloroquine retinopathy, including 36 Asian patients, found that the pericentral pattern occurred in half the Asian patients but only 2% of the white patients. 31 The mechanism for this finding is unclear, but because pericentral.
