Hydroxychloroquine (Plaquenil). Diffuse retinal degeneration extending to the periphery associated with hydroxychloroquine retinal toxicity is illustrated with montaged color fundus photography (a and b). These findings were confirmed with full-field electroretinography which shows generalized depression of both rod and cone function in both eyes (c). The corresponding cross-sectional spectral domain-OCT illustrates the structural correlates of functional loss: there is diffuse pericentral ellipsoid zone loss associated with cystoid macular edema (d and e)
