It is known that some people who take hydroxychloroquine for more than five years and/or in high doses are at increased risk of damage to their retina, the light sensitive layer of cells at the back of the eye. This is known as retinal toxicity or retinopathy.
How does hydroxychloroquine affect your eyesight?
Plaquenil binds to retinal pigment cells, causing adverse changes in vision that occur slowly over time. Objects may start to appear blurry or distorted. In the most serious cases of Plaquenil-induced retinal toxicity, the macula is completely destroyed.
Does hydroxychloroquine cause blindness?
It’s generally safe at normal doses, but higher amounts can damage the retina, the light-sensitive tissue at the back of the eye, and result in partial or complete blindness.
Is Plaquenil eye damage reversible?
In general, hydroxychloroquine and chloroquine retinopathy are not reversible, and even following drug cessation, cellular damage appears to continue for a certain period of time. However, the earlier the retinopathy is recognized, the greater the chance of visual preservation.
What are the symptoms of retinal toxicity?
Retinal toxicity is most frequently characterized by symptoms of central visual loss including reading difficulties, reduced color vision, and central scotomata. Maculopathy ranging from a subtle disturbance of the retinal pigment epithelium to bull’s-eye maculopathy has been described.
What does retinal toxicity feel like?
In the early stages of HCQ retinal toxicity, most of the patients could be asymptomatic. When the first symptoms start to appear their complaints are the following: trouble with reading, diminished color vision, fine visual alteration due to the central or paracentral scotoma.
What are the bad side effects of hydroxychloroquine?

- headache.
- dizziness.
- loss of appetite.
- nausea.
- diarrhea.
- stomach pain.
- vomiting.

What kind of eye problems can Plaquenil cause?
In some people, Plaquenil can cause a condition called hydroxychloroquine retinopathy, often referred to as bulls-eye maculopathy. (The condition can cause the appearance of a target, or bulls-eye ring, on the retina surrounding the macula.)
How often do you need eye exams on Plaquenil?
Patients starting treatment with Plaquenil should have a baseline eye examination within the first year of taking this medication and then regular screenings thereafter; every six months or yearly as advised by your eye doctor.
What causes Cyanopsia?
Cyanopsia is a medical symptom and not a sign. It is a purely subjective state and can be caused by a physical or functional abnormality of the eye, a physical or functional abnormality of the brain, or be purely psychological.
