While many of these can be grouped by anatomic location or type of toxicity, there are also individual medications with characteristic effects. In this article, we will describe several major categories of pharmacologic retinal toxicity and discuss examples of individual medications. Hydroxychloroquine drug interactions Can someone with glucoma take plaquenil Home remedies plaquenil hyperpigmentation Jan 01, 2008 Note the perifoveal crystals and peripapillary mottling of the retinal pigment epithelium. Esther Kim, BA, is a medical student at the New York University School of Medicine. Howard F. Fine, MD, MHSc, is the medical director of the Gerstner Clinical Research Center and assistant professor in the Department of Ophthalmology at Columbia University Medical Center in New York. Oct 01, 2019 A rare inherited retinal dystrophy disorder characterized by spots of black bone-spicule pigmentation of the retinal pigment epithelium. It is manifested with decreased vision in low light or in the night, followed by decreased peripheral vision, and, eventual decreased central vision. On examination, a telltale sign of hydroxychloroquine toxicity is a bilateral change in the retinal pigment epithelium of the macula that gives the commonly described appearance of a bull’s-eye. This is a late finding, however, and too late for screening to be useful. Both medications have been shown to bind melanin and to concentrate in the iris, ciliary body and retinal pigment epithelium, altering normal physiologic function. Chloroquine (Aralen) and hydroxychloroquine (Plaquenil) are traditional antimalarial agents now used in the treatment of autoimmune diseases, including rheumatoid arthritis (RA) and systemic lupus erythematosus (SLE).

Mar 15, 2002 In the left eye, there was some mild mottling of the retinal pigment epithelium RPE in the macula. There was no subretinal fluid, but a foveal light reflex was present. Also, there were bone spicules in the inferior retina of the left eye. Our patients left eye shows bone spicules in the inferior retina. Later, central pigmentation develops with a hollow of depigmentation, mainly inferior to the fovea, creating the “bull’s eye” pattern. Advanced cases may demonstrate widespread retinal pigment epithelium atrophy, with a reduced visual field and decreased night vision. 3 Visual field. Jun 11, 2009 Canthaxanthine is a vitamin A derivative used in the treatment of psoriasis and eczema, and had been used previously as an oral tanning agent.
