It is generally well tolerated, but retinopathy is a concern. Retinopathy is rare, but is sight threatening, generally irreversible and may progress even after cessation of therapy. Although a number of risk factors have been proposed (such as duration of therapy and cumulative dose), the many exceptions (e.g. Plaquenil hypercalcemia Can i take plaquenil and imuran together Plaquenil for adenomyosis Rarely, they report colored rings around lights, haloes and glare which are worse at night. The condition is reversible with discontinuation of the drug. Notably other medications may also cause corneal verticillata including chloroquine and hydroxychloroquine, indomethacin, and phenothiazines and is also seen in Fabry’s disease. Hydroxychloroquine can cause variable ocular adverse effects including corneal deposits, posterior sub-capsular cataract, ciliary body dysfunction and toxic retinopathy. Toxic retinopathy caused by HCQ has been recognized for many years. Patients with toxic retinopathy usually complain of blurry vision. Hydroxychloroquine crystals have been found in the tear film, which may aggravate some sicca patients and contact lens wearers. Toxic maculopathy is usually reversible only in its earliest phases. If these drugs have caused skin, eyelid, corneal hydroxychloroquine or hair changes, this may be an indicator of possible drug-induced retinopathy. Novel technologies such as optical coherence tomography (OCT), fundus autofluorescence (FAF) and multifocal electroretinogram (mf ERG) may provide the earliest structural and functional evidence of toxicity in these stages. Retinopathy on low-dose HCQ, or no retinopathy after a very large cumulative dose of HCQ) highlight our limited understanding of the disease process.

Hydroxychloroquine sulfate dosage for lupusWhat is hydroxychloroquine is for Background The American Academy of Ophthalmology recommendations on screening for chloroquine CQ and hydroxychloroquine HCQ retinopathy are revised in light of new information about the prevalence of toxicity, risk factors, fundus distribution, and effectiveness of screening tools.

Cornea verticillata; Vertex keratopathy Chloroquine toxicity is characterized by whorl-like corneal epithelial deposits. Medications of the chloroquine family, including chloroquine Nivaquine. Keywords Confocalmicroscopy. Cornea. Hydroxychloroquine Introduction Vortex keratopathy cornea verticillata is characterized by a whorl-like pattern of greyish or golden-brown deposits in the corneal epithelium. It occurs in Fabry’s disease and as a side effect of various systemic medications, namely If cornea verticillata is associated with a drug that is known to produce retinal toxicities, most notably hydroxychloroquine, chloroquine, chlorpromazine, and tamoxifen, patients should be routinely monitored with automated visual fields plus spectral-domain optical coherence tomography SD OCT 20.
