Plaquenil is less toxic than chloroquine; however, long-term use of either drug can result in macular toxicity, leading to devastating irreversible vision loss. The mechanism of this toxicity is not clearly understood, though it is believed that the drug molecule binds to melanin in the retinal pigment epithelium (RPE).

Retinal toxicity is irreversible and can progress after cessation of hydroxychloroquine, thus early screening is important to limit potential vision loss. Baseline screening and annual screening after five years is recommended. Hydroxychloroquine is an effective and relatively safe drug that can cause retinal toxicity in a minority of patients. Early diagnosis is important to stop treatment and prevent possible further damage. Nevertheless, in many cases, screening tests are performed too early and too often, causing an unjustified burden on patients and ophthalmologists. RP Taking Plaquenil long-term or at high doses may cause irreversible damage to the retina of your eye. Stop taking Plaquenil and call your doctor at once if you have trouble focusing, if you see light streaks or flashes in your vision, or if you notice any swelling or color changes in your eyes. Binding of the drug to melanin in the RPE contributes to, or prolongs, its toxic effects. This leads to disruption and damage to the photoreceptors and outer nuclear and plexiform layer, sparing the foveal center and resulting in the “bull’s eye” appearance in the late stage of the disease.
