Pattern of Retinopathy: Although the locus of toxic damage is parafoveal in many eyes, Asian patients often show an extramacular pattern of damage.

These guidelines were updated in February of this year, given the emergence of more sensitive diagnostic techniques and the recognition that risk of toxicity from years of hydroxychloroquine use is greater than. HealthDay—Hydroxychloroquine HCQ blood levels are useful in predicting retinopathy among patients with systemic lupus erythematosus SLE, according to a study published online Sept. 18 in. Risk of Toxicity: The risk of toxicity is dependent on daily dose and duration of use.

We found the results on high body mass index particularly concerning, as we capped the dose of hydroxychloroquine at 400 mg daily, no matter how high the body mass index," the authors wrote. This is the first study that focuses on assessing retinopathy risk by tracking hydroxychloroquine blood levels.
