Abstract
PURPOSE: Subconjunctival orbital fat prolapse has been rarely described in the literature and is frequently confused with other conjunctival tumours, such as dermolipoma. The purpose of the present study was to describe the clinical features and treatment of a series of patients with subconjunctival orbital fat prolapse. METHODS: Review of clinical records. RESULTS: Twelve patients with subconjunctival orbital fat prolapse were identified. Eight had a superotemporal prolapse and five of these were bilateral. All but one were male and most were elderly and tended to be obese. Five of these patients underwent surgical excision of the prolapsed fat for symptoms of discomfort or for cosmesis. Four atypical unilateral cases were seen in younger patients with fat prolapse occurring superonasally in three and inferiorly in one. In one case there was a history of trauma CONCLUSIONS: Subconjunctival orbital fat prolapse typically occurs superotemporally in obese elderly males and is easily differentiated from other lesions, such as dermolipoma. The prolapsed orbital fat may be excised via the conjunctiva.
