An adult patient with a medical history of systemic lupus erythematosus and cystic fibrosis was seen with painless, rapidly declining vision in both eyes of 1-month duration. The patient had initially seen a general ophthalmologist 1 week after noticing a change in vision and was diagnosed as having bilateral cataracts. Given a continued decline in vision over the next 2 weeks, the patient sought a second opinion. The patient reported taking 400 mg of hydroxychloroquine sulfate daily (6.3 mg/kg/d) during the past 2 years, with normal renal function, but denied any recent change in medications.
