Hydroxychloroquine retinopathy despite regular ophthalmologic evaluation: a consecutive series.

Abstract

We describe a consecutive series of patients with hydroxychloroquine (HCQ) retinopathy. Their clinical features illustrate that with normal renal function there is no threshold for total dosage for HCQ toxicity; that color vision testing is important; that almost all patients complain of altered central vision as their first symptom; and that a normal optic fundus does not exclude the diagnosis. Finally, HCQ retinopathy may progress even when the agent is stopped.
