Severe and irreversible retinal damage has been reported with the use of hydroxychloroquine. Risk factors for retinal damage include daily doses more than 6.5 mg/kg 5 mg/kg base of actual body weight, durations of use greater than 5 years, subnormal glomerular filtration, use of concomitant drugs such as tamoxifen, and concurrent macular disease. Per the prior 2011 AAO guidelines the recommended maximum dose to minimize HCQ retinal toxicity was 6.5 mg /kg based on ideal body weight 2. The advantage of the real body weight formula is that it distributes the risk evenly on a broad range of body habitus. Irreversible retinal damage observed in some patients who had received hydroxychloroquine sulfate; significant risk factors for retinal damage include daily doses of hydroxychloroquine sulfate greater than 6.5 mg/kg 5 mg/kg base of actual body weight, durations of use greater than five years, subnormal glomerular filtration.
