Central serous chorioretinopathy after epidural steroid injection.

Central serous chorioretinopathy (CSC) is a condition characterized by serous detachment of the neurosensory retina in the posterior pole. Corticosteroids administered by various routes is reported as a possible cause of CSC. We report the cases of two patients who developed CSC after receiving a corticosteroid injection in the epidural space for the treatment of back pain. In both patients, the accumulation of subretinal fluid spontaneously resolved within several weeks. Patients who develop CSC after epidural analgesia with corticosteroids should be alerted to the possible relationship between CSC and this treatment. Clinicians should advise all patients with CSC to avoid systemic corticosteroids administered by any route, unless they have a compelling medical indication. Pharmacists should advise patients to seek evaluation if visual changes occur during or after corticosteroid therapy.
