Visual fields and SD-OCT are not necessary for baseline measurements unless there is pre-existing retinal pathology that needs to be documented. Macular Society Eye screening for patients taking hydroxychloroquine. Hydroxychloroquine is a medication used to treat several conditions including rheumatoid arthritis, systemic lupus erythematosus, some skin conditions especially photosensitive ones and others that involve inflammation. Hydroxychloroquine retinopathy. It is known that some people who take hydroxychloroquine for more than five years and/or in high doses are at increased risk of damage to their retina, the light sensitive layer of cells at the back of the eye. This is known as retinal toxicity or retinopathy. Today, it is used to treat rheumatoid arthritis, some symptoms of lupus, childhood arthritis (or juvenile idiopathic arthritis) and other autoimmune diseases.

Ophthalmology. 2011 Oct;118102100; author reply 2101. BACKGROUND The American Academy of Ophthalmology recommendations for screening of chloroquine CQ and hydroxychloroquine HCQ retinopathy were published in 2002, but improved screening tools and new knowledge about the prevalence of toxicity have appeared in the ensuing years. Multifocal Electroretinopathy measures electrical responses of various cell types in the retina. It is thought that although the bull’s eye seen on ophthalmic exam represents a disruption of the pigmented part of the retina, it is the photoreceptors that are the targets of hydroxychloroquine toxicity. Very rarely, high doses of hydroxychloroquine may damage the retina the layer of cells in the back of the eye that detects light and allows you to see. This is prevented by keeping the dose low. While you are taking hydroxychloroquine annual eye tests may be recommended.
