Microvascular Ocular Changes of Systemic Lupus Erythematous
The goal of this observational study is to to assess the ocular microvascular status of SLE patients with inactive disease and without ocular involvement. The main questions it aims to answer are: * the choroidal vascular status and thickness in SLE * the retinal macular microvascular status and structure in SLE Participants will be assessed with Spectral Domain Optical Coherence Tomography (SD-OCT). Researchers will compare SLE patients with healthy controls matched for age and sex.
