About this study

Official title: Incidence and Risk Factor Evaluation for Toxic Maculopathy Associated With Hydroxychloroquine and Chloroquine

The purpose of this study is to evaluate the incidence and risk factor of toxic maculopathy who treated with hydroxychloroquine or chloroquine due to their autoimmune disease such as rheumatoid arthritis or systemic lupus erythematosus. Total 5-year of the study periods, the investigators will screen these patients by baseline examination (Fundus photography, fundus autofluorescence, spectral-domain optical coherence tomography, Humphrey visual field test and multifocal electroretinography) and observe with same examination for every year.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Composite ExaminationProcedure or surgery

    First, patients will get the baseline ophthalmologic exam and medical evaluation by physicians. As a diagnostic method, the composite examination including fundus photography, fundus autofluorescence, spectral-domain optical coherence tomography, Humphrey visual field test and multifocal electroretinography will be tested once every year.

What does the primary outcome measure?

Incidence of toxic maculopathy associated with HCQ or CQ (time frame: 1 years). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
