In late stages of the disease, full-field ERG may be nonrecordable even in the presence of a demonstrable field by kinetic perimetry. We have found recordable, though attenuated, multifocal ERG responses in patients with RP.

    Hydroxychloroquine is a quinoline medicine 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. This medicine is not effective against all strains of malaria. Plaquenil hydroxychloroquine is a medicine commonly used to treat patients with systemic lupus erythematosus and rheumatoid arthritis. After prolonged use, it can sometimes damage the macula and cause central vision loss. Typically, the macula loses its orange pigment, giving the appearance of a bullseye. The incidence of retinitis pigmentosa is reported to be 0.251,000 individuals. One can calculate a relative prevalance for antimalarial retinal toxicity at about 0.00,000.3–5 Based on the variable incidence and prevalence data for the collagen vascular disorders in the literature, it is difficult to calculate the exact risk to patients.
