This is known as retinal toxicity or retinopathy. Overall, around seven patients out of every 100 taking hydroxychloroquine for more than five years may develop retinopathy that can be detected with specialised tests. The risk is much higher in patients who have been taking the drug for 20 years or more. In these May 12, 2016 Plaquenil can prove toxic to the retina, threatening the vision. Regular eye examinations are essential for those patients taking plaquenil because over time the retina can become damaged beyond repair. Regular medical monitoring is the only way to ensure that toxicity is not occurring.

Eye screening by an ophthalmologist is important to help identify any damage to the eye at the earliest stage possible. Of course the aim is avoid drug related retinal toxicity, which on ophthalmic examination, appears as the classic Bull’s eye change affecting the macula. Once retinal toxicity from hydroxychloroquine occurs, it is thought that the retinal changes are permanent and the disease can progress even if hydroxychloroquine is stopped for 1 to 3 years.
