In 2016, with new scientific data, the American Academy of Ophthalmology revised their screening recommendations for patients on chloroquine for longer than 1 year 5. The two most important risk factors for retinopathy are the duration of chloroquine treatment and a daily dose of chloroquine 2.3 mg/kg of the patient's actual body weight.
