Abstract (EN): Purpose: To evaluate choroidal morphology and thickness at the posterior pole of individuals affected by multisystemic autoimmune diseases and without known ophthalmologic manifestations. Methods: Retrospective cross-sectional study including 75 patients with autoimmune diseases (divided according to their specific disease) and 80 healthy controls. A spectraldomain optical coherence tomography using enhanced depth imaging was performed and choroidal thickness was measured in the center of fovea and at 500 mm intervals along a horizontal section. Results: Lupus patients presented a thicker subfoveal choroid than controls (408.624 vs. 356.536, P < 0.001) and in all the other measurements (P < 0.001 to P = 0.003). Rheumatoid arthritis and other autoimmune diseases had an overall thinner choroid than controls (297.867 vs. 356.536 subfoveally, P = 0.004; P = 0.005-0.019 in other measurements). Results were adjusted for the covariates age (P = 0.007), spherical equivalent (P, 0.001), and systemic steroids dose (P = 0.004). Hypertension (P = 0.102), diabetes mellitus (P = 0.672), time since the beginning of therapy with hydroxychloroquine (P = 0.104) and its cumulative dose (P = 0.307), or use of other immunosuppressives (P = 0.281) had no influence on the mean choroidal thickness. No morphologic abnormalities were found. Conclusion: The choroid may be subclinically involved in autoimmune diseases. However, the choroidal response seems to differ depending on the autoimmune disease. Infiltrative mechanisms specific for lupus may justify the thickened choroid found in these patients.
