Prolapsed orbital fat: 15 consecutive cases.

Prolapsed orbital fat has rarely been described and is often confused with other conjunctival tumours, such as dermolipoma. We describe the clinical features and treatment of 15 patients with prolapsed orbital fat. We report here our experience in 15 consecutive patients who presented to the Vision Institute of Federal University of São Paulo, Brazil, between July 2004 and December 2007. Age, sex, presenting complaint, physical findings, associated local and systemic diseases, type of treatment, and complications were recorded. Ten patients were men, and ages ranged from 44-86 (mean 68). Eleven patients presented with unilateral disease. Thirteen had superotemporal prolapse, and two atypical superonasal prolapse. Two gave a history of trauma. All patients had the prolapsed fat excised for cosmetic reasons. There were no complications. Orbital fat prolapse is usually superotemporal, mainly in men, and is easily differentiated from other lesions, such as prolapsed lacrimal gland. Excision is always indicated, usually for cosmetic reasons.
