| Popis: | The ophthalmologic safety of antimalarial drugs is well established, but absolute safety cannot be assured. Three types of side effects may develop. Corneal deposits and neuromuscular-associated blurred vision are always reversible and therefore benign. Visual loss has occurred in patients with retinopathy. Retinopathy may be divided into true retinopathy and premaculopathy. It is true retinopathy that may be associated with visual loss, while premaculopathy consists of subtle visual field and funduscopic abnormalities. These premaculopathic changes are generally completely reversible with drug discontinuation and have not been shown to progress. Hydroxychloroquine appears safer than chloroquine when currently accepted equivalent doses are’ used. Fewer than 20 patients with true retinopathy caused by hydroxychloroquine have been reported; more patients have developed true retinopathy when taking chloroquine. The safety profile is most dependent on low daily dose and regular ophthalmologic monitoring. The optimal strategy of ophthalmologic testing has not yet been determined, but visual acuity, funduscopic examination and visual field examination should be monitored. Self-administered ophthalmologic testing with Amsler grids may contribute additional safety but is not a replacement for physician testing. |
