Solving the Hydroxychloroquine Dosing Dilemma With a Smartphone App

Abstract
Hydroxychloroquine retinopathy (HCR) is a potentially blinding disease. Once HCR is detected, there is no treatment and the disease often continues to progress, even when the medication is stopped. Hence, primary prevention by appropriate dosing of hydroxychloroquine offers the best chance of minimizing the risk of HCR.
