    Retinitis Pigmentosa. Generalized retinal degenerations such as retinitis pigmentosa are best followed by full-field ERG. 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. 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.

    We conducted a retrospective analysis of patients with advanced HCQ retinopathy (n = 11), pericentral RP (n = 8) and diffuse RP (n = 8). To study whether the ERG and other clinical findings help to distinguish between advanced hydroxychloroquine (HCQ) retinopathy and pericentral or diffuse retinitis pigmentosa (RP) with similar fundus appearance.
