“…6 Therefore, SLE choroiditis is thought to be caused by focal inflammation at the choriocapillaris, 7 and subsequent focal vascular compromise results in ischemia in overlying RPE cells, which causes a breakdown of the normally impermeable outer blood-ocular barrier provided by this layer. 5 Therefore, systemic corticosteroid therapy is believed to be an effective treatment. Some evidence suggests, however, that the systemic application of corticosteroid can result in choroidal hyperpermeability, which may lead to a breakdown of the blood-retinal barrier or alter RPE ion transport capabilities, and cause serous retinal detachment.…”
