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.
Review of clinical records.
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
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.
结膜下眶脂肪脱垂在文献中鲜有描述，且常与其他结膜肿瘤如皮样脂肪瘤相混淆。本研究的目的是描述一系列结膜下眶脂肪脱垂患者的临床特征及治疗方法。
回顾临床记录。
共识别出12例结膜下眶脂肪脱垂患者。8例为颞上侧脱垂，其中5例为双侧。除1例女性外其余均为男性，大多数患者为老年人且倾向于肥胖。其中5例患者因不适症状或出于美容目的接受了脱垂脂肪的手术切除。在较年轻患者中发现4例非典型单侧病例，其中3例脂肪脱垂发生于鼻上方，1例发生于下方。1例有外伤史。
结膜下眶脂肪脱垂通常发生于肥胖老年男性的颞上侧，且易于与其他病变如皮样脂肪瘤相鉴别。脱垂的眶脂肪可通过结膜进行切除。
