    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).

    Newer guidelines state that daily dose 5mg/kg of real weight/day can lead to toxicity. 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 Retinal toxicity associated with chronic exposure to hydroxychloroquine and its ocular screening. New recommendations for the screening of HCQ/CQ maculopathy were provided by The American Academy. Severns ML. Using multifocal ERG ring ratios to detect and follow Plaquenil retinal toxicity a review of mfERG ring ratios in Plaquenil.

    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.

Moreover, Chloroquine inhibits autophagy as it raises the lysosomal pH, which leads to inhibition of both fusion of autophagosome with lysosome and lysosomal protein degradation 4. References. 1.
