    Plaquenil retinal screening guidelines afters stopping


    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).

    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. Thus, annual screening is recommended after five years for non-high risk patients. Remember, any patient who is at a high risk for Plaquenil toxicity should be examined on an annual basis following the baseline exam. 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.

    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.

    The treatment for early toxicity usually requires stopping Plaquenil. Patients taking Plaquenil should have an early baseline assessment of visual acuity, macular appearance and central field sensitivity. The macular appearance and function should be checked at intervals of 6 to 12 months. The latest screening guidelines were published in 2016 by the American Academy of Ophthalmology. Eye care specialists provide a valuable service when screening for Plaquenil retinal toxicity and advising the treating physician or rheumatologist with regards to the patient’s risk, safe dosing and appropriate screening procedures. The physician should note any visual symptoms as well. After 5 years of therapy, an ocular examination, 10-2 threshold field testing and any one objective testing is recommended 1, 4.
