Retinal toxicity associated with chronic exposure to hydroxychloroquine and its ocular screening. Review. A Geamănu. The mechanism of hydroxychloroquine toxicity is not completely understood. Standard automated perimetry 10-2 testing with white spot can be a sensitive test for the early stages of toxicity, it must include pattern. Our patient demonstrates the importance of using the new recommended screening tools for the detection of early hydroxychloroquine toxicity. 10-2 HVF, SD-OCT, autofluorescence, or mfERG might have detected the hydroxychloroquine retinal toxicity on the day of her presenting symptoms and possibly earlier, potentially limiting the amount of.
