Optic neuropathy as a presenting feature of systemic lupus erythematosus: two case reports and literature review

Systemic lupus erythematosus (SLE) may affect the eyes and/or visual system in up to a third of patients; however, optic nerve involvement has been rarely reported. SLE presenting as optic neuropathy is exceptional. We report two new cases of optic neuropathy as a presenting feature of SLE. The first patient presented with an ischemic optic neuropathy and antiphospholipid antibodies, and the second presented with optic neuritis. A literature review for previous cases of SLE presenting as optic neuropathy was performed. Early diagnosis of SLE-associated optic neuropathy is warranted and leads to a better prognosis.
