In this report we describe a patient with systemic lupus erythematosus
who was clinically stable after treatment with the antimalarial drug
chloroquine and purse cyclophosphamide therapy. Three months after the
discontinuation of chloroquine, the patient developed cilioretinal ar
tery occlusion that was the only the manifestation of a clinical flare
-up without evidence of clinical disease activity elsewhere. This case
report confirms the clinical belief that the antimalarial agents can
maintain the clinical quiescence of systemic lupus erythematosus and i
ts discontinuation is associated with an increase in the risk of clini
cal flare-up.
