Plaquenil is used to treat or prevent malaria, a disease caused by parasites that enter the body through the bite of a mosquito. Malaria is common in areas such as Africa, South America, and Southern Asia. Symptoms of retinal damage from plaquenil Hydroxychloroquine and alcohol Cornea verticillata chloroquine The hallmark of hydroxychloroquine toxicity is bilateral pigmentary retinopathy. Patients with early retinal findings are often asymptomatic despite having subtle paracentral scotomas. Patients with early retinal findings are often asymptomatic despite having subtle paracentral scotomas. The subjective component to HCQ retinopathy screening is an automated visual field testing the central 10° of vision. The earliest signs of HCQ retinopathy on a central visual field may present as a cluster of paracentral points with decreased sensitivity. These points may be only mildly depressed. Two kinds of diabetic retinopathy have the potential to diminish vision In nonproliferative retinopathy, blood vessels in the retina deteriorate. Deteriorating blood vessels can become blocked or deformed. Fluids, fats and proteins leak out of the abnormal blood vessels. Fluid can collect in the retina. Plaquenil is also an antirheumatic medicine and is used to treat symptoms of rheumatoid arthritis and discoid or systemic lupus erythematosus. This medicine is not effective against all strains of malaria.

Retinopathy Guide Causes, Symptoms and Treatment Options. Plaquenil Oral Uses, Side Effects, Interactions.. Patients in earlier stages of hydroxychloroquine retinal toxicity usually do not experience symptoms, though the rare patient may note a paracentral scotoma that causes trouble with reading as well as diminished color vision. However, most patients usually notice symptoms only after scotomas have become severe. Plaquenil is the brand name for the prescription drug hydroxychloroquine. It's used to treat and prevent malaria infection, and to reduce symptoms and progression of autoimmune diseases such as lupus, rheumatoid arthritis, and others. Malaria is spread by mosquitoes. When using both these tools, keep in mind the following from Melles and Marmor’s recent study 1. “Retinal toxicity from hydroxychloroquine use cannot be completely prevented, but effective screening should recognize retinal toxicity before symptoms or significant risk of central vision loss appear ie.
