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. Plaquenil lo loestrin fe Chloroquine and tlr signaling Hydroxychloroquine and l lysine Although hydroxychloroquine retinal toxicity is thought to be rare, recent studies suggest it may have a higher prevalence than previously recognized. A large study examining patients with more than 5 years of HCQ use were evaluated with 10-2 visual fields or spectral-domain optical coherence tomography SD OCT. 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. Spectral domain optical coherence tomography as an effective screening test for hydroxychloroquine retinopathy the “flying saucer” sign. Fishman GA, Choi D, Shahidi M. Selective thinning of the perifoveal inner retina as an early sign of hydroxychloroquine retinal toxicity. Eye Lond 2010; 24 5756–762. quiz 763. 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.

There is no single best test for detecting hydroxychloroquine toxicity. However, SD-OCT and VF are good screening tests, and FAF and mfERG can help confirm a diagnosis of suspected retinal toxicity from hydroxychloroquine. Early detection of toxicity is critical to prevent permanent visual loss. 1. Jorge A, Ung C, Young L, Melles RB, Choi HK.

There is damage visible in the outer retina in a perifoveal distribution. Related files Hydroxychloroquine Plaquenil and chloroquine cause ocular toxicity to various parts of the eye such as the cornea, ciliary body, and retina. Chloroquine can also induce cataract formation; however, no reports of hydroxychloroquine and cataract have been reported. This article focuses upon hydroxychloroquine retinopathy.
