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.

The deposits do not stain and are almost always bilateral. Plaquenil side effects start off by effecting the surface of the eye the cornea leading to verticillata. Verticillata are deposits of salts within the corneal epithelium. This does not cause any symptoms to the patient and is reversible when the medication is stopped. 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. Disease 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.

Hydroxychloroquine toxicity - EyeWiki. Retinal Screening for Hydroxychloroquine Plaquenil Toxicity.. Hydroxychloroquine, sold under the brand name Plaquenil Sanofi-Aventis, is an antimalarial drug that has gained widespread use in treating various autoimmune diseases, including systemic lupus erythematosus and rheumatoid arthritis. 1 By some estimates, more than 150,000 patients are on long-term therapy with this medication in America alone. 2 Retinal toxicity associated with HCQ use is relatively rare, estimated at 1 percent after five years and rising with continued therapy. 3 However. Cornea verticillata, also called vortex keratopathy or whorl keratopathy, is a condition characterised by corneal deposits at the level of the basal epithelium forming a faint golden-brown whorl pattern. It is seen in Fabry disease or in case of prolonged amiodarone intake. Causes Amiodarone Fabry’s disease Chloroquine Hydroxychloroquine Indomethacin Phenothiazines etc. Corneal verticillata, or vortex keratopathy, manifests as a whorl-like pattern of golden brown or gray deposits in the inferior interpalpebal portion of the cornea in a clockwise fashion Fig 12-15. A variety of medications bind with the cellular lipids of the basal epithelial layer of the cornea due to their cationic, amphiphilic properties.
