title: Orbital pseudotumor: clinical features and outcomes.
abstract: To describe the clinical characteristics of orbital pseudotumor, a retrospective analysis was performed on patients with orbital pseudotumor at Siriraj Hospital for ten years. Forty-nine patients (24 males and 25 females; 62 eyes) with a mean age of 43.75 years were included (a mean follow-up of 25 months). Thirty-six patients (73.5%) had unilateral disease. The clinical features were proptosis (79.6%), ocular motor deficit (61.2%), pain (51%), lid swelling or lid mass (44.9%), ptosis (24.5%), and chemosis (18.4%). The most common presenting sign was proptosis (49%). All were treated with corticosteroids with clinical improvement in 40 (81.6%) patients. Ten (83.3%) of 12 patients with visual loss improved with mean recovery time of 10.3 days. Ocular motility recovered in 24 (80%) patients, occurring an average of 17.8 days after initiation of therapy. It is concluded that the clinical features of orbital pseudotumor are varied. Most patients were improved with corticosteroids treatment.
