Co-existing liver and kidney disease may also impact on the genesis of plaquenil retinal toxicity. One additional issue is the fact that chloroquine and hydroxychloroquine are cleared by both the liver and kidney. Any compromise of these organs may also impact on potential toxicity. Said another way.
