Hydroxychloroquine Retinopathy - Misinterpretation of VIsual Fields, Part F
Please see parts A-E of this series first. Unfortunately, it is common for hydroxychloroquine retinopathy to progress even after cessation of drug. This patient's drug was stopped in 2010, 2 years after visual changes were noted, and at the time that a bulls eye lesion had first developed. Now, two years later, the width of the annulus of atrophic retina has widened. Note the location of the edge of the atrophy (green arrow) relative to the landmark blood vessel (yellow arrow). The spared foveal zone has shrunk (white bars).
