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. How long for hydroxychloroquine to leave the body Chloroquine phosphate dosage in child Background/Aims Hydroxychloroquine HCQ retinopathy may result in severe and irreversible vision loss, emphasising the importance of screening and early detection. The purpose of this study is to report the novel finding of early optical coherence tomography OCT abnormalities due to HCQ toxicity that may develop in the setting of normal Humphrey visual field HVF testing. Methods Data from. May 02, 2018 OCT, on the other hand, is an objective, structural test, that is “highly speciﬁc, and generally sensitive for levels of damage that might be visually signiﬁcant.” 1 Although OCT might depict initial distinct focal interruption of the photoreceptor outer segment structural lines, it is more useful for showing localized thinning of the.
