Rights and Permissions

Based on the present literature, in March 2016, new recommendations of the American Academy of Ophthalmology for ophthalmic screening tests in patients treated with chloroquine and hydroxychloroquine were published. These recommendations emphasized the fact that toxicity is related to the dose calculated by real weight. The recommended hydroxychloroquine and chloroquine doses have been limited. It is no longer recommended to calculate the cumulative dose of chloroquine to establish the risk of toxicity. Kidney failure and the use of tamoxifen are proven risk factors of ocular complications in these patients. The screening agenda was established and available diagnostic methods were evaluated. Screening in patients treated with chloroquine derivatives may prevent an irreversible complication-toxic retinopathy. The present recommendations warn against making premature decision on medicine withdrawal, especially in the light of the most recent studies on their beneficial systemic influence. This paper systematizes the information on ophthalmological screening in chloroquine derivatives users.
