Twenty patients with unilateral exophthalmos secondary to orbital tumors underwent fundus photography; 16 underwent fluorescein angiography. Choroidal folds were found in 15 eyes. The location of each tumor with respect to the globe was determined by computed tomography. In addition, most patients underwent B-scan ultrasonography and surgical exploratory procedures. Choroidal folds were more common in patients with greater amounts of exophthalmos and with anteriorly located tumors. Moreover, the pattern of choroidal folds generally reflected the location of the tumor within the orbit. Comparison with the uninvolved fellow eyes showed that preoperative refractive errors were usually shifted toward hyperopia with intraconal tumors, whereas extraconal tumors were typically associated with higher astigmatic errors on the involved side.
20例因眼眶肿瘤导致单侧眼球突出的患者接受了眼底照相；16例接受了荧光素血管造影。在15只眼中发现了脉络膜皱褶。通过计算机断层扫描确定每个肿瘤相对于眼球的位置。此外，大多数患者接受了B超检查和手术探查。脉络膜皱褶在眼球突出程度较大且肿瘤位于前部的患者中更为常见。此外，脉络膜皱褶的形态通常反映了肿瘤在眼眶内的位置。与未受累的对侧眼相比，术前屈光不正通常在圆锥内肿瘤患者中向远视偏移，而圆锥外肿瘤通常与患侧更高的散光误差相关。
