    Plaquenil induced retinal toxicity is reversible if detected early and plaquenil dosage altered or the medication discontinued. Even suspicious early plaquenil toxicity warrants communication with the patient’s treating physician, and meaningful coordination of care would include a report even if the findings are normal. In particular, chloroquine and hydroxychloroquine Plaquenil are two such medications, with the potential for retinal toxicity. Given that the retinal damage from these medications is largely irreversible, screening by a retinal specialist is critical to detect early retinal toxicity to try and limit the extent of visual loss. Recent studies suggest a higher prevalence of hydroxychloroquine retinal toxicity than previously recognized. A study by Wolfe and Marmor of 4000 patients with. Retinal damage caused by hydroxychloroquine is generally reversible if caught early, but damage caused by chloroquine may not be. You can also monitor yourself between visits with a special grid called an Amsler grid, which can be obtained through your ophthalmologist.

Several risk factors may increase the likelihood of retinal toxicity from Plaquenil such as. Several authors have questioned the utility of screening for hydroxychloroquine toxicity given the low yield, high cost, and the difficulty in diagnosing the condition early enough to prevent damage. 43–46 Nevertheless, toxicity does occur, and if retinal and functional changes are detected early, severe visual impairment can be averted. 47, 48 Use of static perimetry through the vertical meridian with a red test object may be the best method to detect an early paracentral scotoma. 49. Retinal toxicity from hydroxychloroquine is rare, but even if the medication is discontinued, vision loss may be irreversible and may continue to progress. It is imperative that patients and physicians are aware of and watch for this drug’s ocular side effects.
