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.

Chloroquine toxicity remains a problem in many parts of the world, but is seen less frequently in the United States where the drug largely has been. SD-OCT images demonstrated loss of photoreceptor inner segment/outer segment IS/OS junction and a downward “sink-hole” displacement of inner retinal structures in areas of hydroxychloroquine toxicity corresponding to HVF 10-2 defects and ophthalmoscopic clinical examination findings. The actual incidence of retinal toxicity from hydroxychloroquine is difficult to pin down because there is usually a long time between being started on the drug and the start of any identifiable retinal toxicity. The overall rate of probable retinal toxicity is in the range of 1 of every 200 people treated. 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 preferential loss of photoreceptor IS/OS junction makes SD-OCT an ideal tool to identify early changes associated with Plaquenil retinal toxicity. How to Succeed in Plaquenil Screenings. What can Hydroxychloroquine Plaquenil do to my eyes?. Hydroxychloroquine Plaquenil Toxicity and.. Ocular Surgery News The American Academy of Ophthalmology has published several dosing and screening recommendations for hydroxychloroquine to avoid potential retinal toxicity, yet some patients. Plaquenil hydroxychloroquine is a medicine commonly used to treat patients with systemic lupus erythematosus and rheumatoid arthritis. After prolonged use, it can sometimes damage the macula and cause central vision loss. Typically, the macula loses its orange pigment, giving the appearance of a bullseye. Plaquenil can prove toxic to the retina, threatening the vision. Regular eye examinations are essential for those patients taking plaquenil because over time the retina can become damaged beyond repair. Regular medical monitoring is the only way to ensure that toxicity is not occurring.
