Hydroxychloroquine (Plaquenil) Eye Exams
Hydroxychloroquine, sold under the brand name Plaquenil, is used to treat lupus, rheumatoid arthritis, Sjögren's and other inflammatory conditions. Many pharmacies now fill the generic, so your bottle may only say hydroxychloroquine. It is the same medicine, and it needs the same eye checks.
Why this medicine needs eye exams
Hydroxychloroquine is generally safe, but in a small number of people it can slowly damage the retina, the light-sensitive layer at the back of the eye. The damage does not cause symptoms early on, it cannot be reversed, and it can keep progressing even after the medicine is stopped. Regular screening is how we catch changes early, before they affect your vision.
When to be screened
The American Academy of Ophthalmology recommends:
- A baseline exam when you start the medicine, to make sure there is no existing problem in the macula
- Yearly screening after 5 years of use for people on a typical dose with no major risk factors
Your eye doctor may start yearly checks sooner if you have risk factors.
What raises the risk
- A daily dose above 5 mg per kilogram of your actual body weight
- Taking the medicine for many years
- Kidney disease
- Taking tamoxifen
How we check your eyes
The two main screening tests are an automated visual field test, which maps your central and side vision, and an OCT scan, which shows the layers of the macula in fine detail. At Reimbold Eye Group we compare each year's results with your earlier ones so small changes stand out.
What to bring
Bring your medication bottle or list, your daily dose, how long you have taken it, and the name of your prescribing doctor. With your permission, we can send your results to that doctor.
Questions patients ask
Is hydroxychloroquine the same medicine as Plaquenil?
Yes. Plaquenil is the brand name. Many pharmacies now fill the generic, which is labeled hydroxychloroquine. The eye screening is the same for both.
I feel fine and see well. Do I still need screening?
Yes. Early retinal damage from hydroxychloroquine causes no symptoms. Screening is how it is caught before it affects your vision.
Should I stop taking it if I am worried about my eyes?
No. Do not stop or change your dose on your own. If we see any sign of change, we share the results with your prescribing doctor so you can decide together.
