In less advanced cases, the only findings may be loss of the foveal light reflex and nonspecific pigmentary abnormalities. Once retinal toxicity from hydroxychloroquine occurs, it is thought that the retinal changes are permanent and the disease can progress even if hydroxychloroquine is stopped for 1 to 3 years. Newer techniques for evaluation of retinal disease have been developed and these techniques can detect retinal toxicity earlier. Diagnosis Hydroxychloroquine-induced retinal toxicity Discussion.

Plaquenil is most commonly prescribed to patients with rheumatoid arthritis, systemic lupus, and Sjögren’s syndrome, but it is also sometimes used in dermatological contexts due to its anti-inflammatory properties. The side effect that is of greatest concern is retinal toxicity. Retinal toxicity of Plaquenil may manifest itself with subtle disturbances of the retinal pigment epithelium which may eventually lead to complete destruction of the macula in the form of bull’s-eye maculopathy.
