英文摘要 | Spontaneous subconjunctival orbital fat prolapse is an uncommon but benign entity. It is seldom discussed in the literature, and is sometimes confused with other ocular surface tumors, such as dermolipoma. We present 3 cases, two of which are bilateral, the other being unilateral. Two cases underwent surgical excision due to ocular irritation, and the pathology proved mature adipose tissue compatible with the diagnosis. Computed tomography (CT) was available for 1 case and revealed a fat-compatible radiolucent mass continuous with the intraconal fat. Some other reports have presumed that the intraconal fat was prolapsed from a dehiscence of Tenon's capsule. However, according to our surgical findings, we suggest that the possible weak point for intraconal orbital fat prolapse is between the regions where the rectus muscle tendons penetrate into Tenon's capsule. The fat just bulges anteriorly, but not penetrates the Tenon's capsule and the intermuscular septum. (Chang Gung Med J 2001;24:399-403) |
