They are related drugs with different therapeutic and toxic doses with similar clinical indications for use and manifestations of retinal toxicity. The structure of tamoxifen is similar to other cationic amphiphilic drugs known to produce a retinopathy and keratopathy, including chloroquine, chlorpromazine, thioridazine, and amiodarone hydrochloride. 7 Cases of chloroquine 8 and amiodarone 9 keratopathies have been reported, but, to our knowledge, histopathological features of tamoxifen. Chloroquine CQ is used to prevent and treat malaria and amebiasis,1 while hydroxychloroquine HCQ, a less toxic metabolite of chloroquine, is used to treat rheumatic diseases such as systemic lupus erythematosus SLE, rheumatoid arthritis RA, juvenile idiopathic arthritis JIA and Sjogren's syndrome.2 Both medications can cause corneal deposits, posterior subcapsular lens opacity. In the United States, hydroxychloroquine is most often used for its anti-inflammatory effects in rheumatology and dermatology. Chloroquine is now uncommonly used in favor of its derivative hydroxychloroquine. Chloroquine cornea Chloroquine C18H26ClN3 - PubChem, A Case of Tamoxifen Keratopathy Cornea JAMA Ophthalmology.

Chloroquine Toxicity, Cornea Verticillata SpringerLink. Chloroquine And Hydroxychloroquine Toxicity - StatPearls.. New Plaquenil Guidelines. Abstract. 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. Before the administration of chloroquine, the patient had only a mild skin erythema in the irradiated area, which was consistent with the radiotherapy dose she had received. On day 3 of chloroquine therapy, she developed localized brisk bullous eruptions in the irradiated area, which developed into a patch of fulminant moist desquamation. An in vivo confocal microscopy was also applied to the chloroquine-treated corneas. In both chloroquine- and amiodarone-treated corneas, diffuse cloudiness was observed by slit-lamp biomicroscopy, and its transparency increased with duration of dosing. Confocal microscopy showed punctate dots in the corneal epithelium.
