Retinal toxicity from Plaquenil is of serious concern because even after cessation of the drug, there is little if any visual recovery, and sometimes a progression of visual loss over several years after the drug has been stopped. No medical therapy has proven effective in Plaquenil toxicity other than cessation of the drug. There may be a stage of very early functional loss where cessation of the drug will allow a reversal of the toxicity. :cry:
Peace and Blessings
Look For The Good and Praise It!
