Idiopathic Orbital Inflammatory Disease Attack Associated with Large Serous Detachment Without Anterior and Posterior Segment Inflammation.

Idiopathic orbital inflammatory disease is a benign, non-infectious, and non-neoplastic space-occupying orbital and peri-orbital inflammation with no identifiable local or systemic causes. Patients usually present with eyelid and periorbital erythema and edema, proptosis, and decreased eye movements. In this report, a case of large serous retinal detachment accompanying a unilateral idiopathic orbital inflammatory disease attack is discussed. It demonstrates that very extensive and highly serous retinal detachment may accompany idiopathic orbital inflammatory disease attacks. Dramatic improvement in clinical findings and imaging can be observed with high-dose steroid treatment in a short time.
