The most worrisome toxicity is irreversible damage to retinal pigment epithelium which can lead to blindness. The most recent 2016 guidelines from the American Academy of Ophthalmology AAO recommend the dose of HCQ ≤5 mg/kg real body weight to minimize toxicity1. According to these An appropriate dose is required to minimize the risk of hydroxychloroquine related retinopathy and to permit long-term use in most patients. The overall risk of developing hydroxychloroquine retinopathy in patients on long-term therapy is 7.5% with the risk increasing with higher doses and long-term use.
