One such commonly used medication for dermatologic and rheumatologic inflammatory conditions is hydroxychloroquine (Plaquenil), a chloroquine derivative. It is used to treat many diseases including malaria, rheumatoid arthritis and systemic lupus erythematosus.

This 68 year old woman with systemic lupus erythematosus had been on hydroxychloroquine at a dosage of 400 mg/d 6.52 mg/kg/d for eight years. Although there were many cases with both early field loss and early SD-OCT damage, there were no cases in our population with prominent parafoveal anatomic damage and no field changes at all. Figure 3 shows a case with distinct parafoveal thinning, but field losses that are spotty and might be dismissed as normal or at least left for later confirmation. Marmor, who chaired the Academy’s screening guidelines committee, said the goal in Plaquenil screening is to catch changes at a very early stage when there’s just a minimal amount of loss of vision. “Then, when you stop the drug, the damage won’t progress enough to cross the fovea and affect reading vision.” It is imperative that patients and physicians are aware of and watch for this drug’s ocular side effects. Retinal toxicity from hydroxychloroquine is rare, but even if the medication is discontinued, vision loss may be irreversible and may continue to progress.

Drug interactions with plaquenilChloroquine treatment of amoebic liver abscessOphthalmologic complication of hydroxychloroquine Several reports previously described abnormal OCT findings, including parafoveal thinning and abnormalities in the parafoveal photoreceptor inner segment/outer segment junction in patients with chloroquine or hydroxychloroquine retinal toxicity. However, those patients with noticeable OCT changes had clinical symptoms, visual loss, visual field defects, colour vision deficiency, or abnormal mfERG findings.

Progression of SD-OCT changes after drug cessation. Morphological SD-OCT changes in each group after drug cessation is shown in Fig. 2. An interval change in SD-OCT appearance suggesting structural progression of toxicity was observed in 75 % Early, 71 % Obvious, and 100 % of Severe eyes. Early detection of the maculopathy is of critical importance to discontinue Plaquenil in order to stop or slow retinal damage. Unfortunately, clinically evident early structural changes can be subtle and usually preceded by abnormalities in functional tests such as visual field examination, multifocal electroretinography mfERG, fundus autofluorescence FA imaging, and optical coherence tomography. Plaquenil hydroxychloroquine belongs to a group of medicines called quinolines. Plaquenil is used to treat or prevent malaria, a disease caused by parasites that enter the body through the bite of a mosquito. Malaria is common in areas such as Africa, South America, and Southern Asia.
