Purpose To investigate the appearances of lacrimal gland prolapse on high-resolution CT and multiplanar reconstruction images in order to improve understanding of images of lacrimal gland prolapse and diagnostic accuracy.Material and Methods High-resolution CT images(slice thickness of 0.6 mm)were retrospectively analyzed in 6 patients with lacrimal gland prolapse,and multiplanar reconstruction were applied to observe the position and get CT diagnostic criteria.Results Of the 6 patients,there were bilateral prolapses in 5 patients.The lacrimal gland prolapse had high-resolution CT characteristic features,including htelacrimal fossa empty,varying degrees of the lacrimal gland protuberance in the corresponding level of orbital rim,and lateral upper eyelid swelling.Conclusion High-resolution CT and multiplanar reconstruction is efficacious in diagnosis of the lacrimal gland prolapse.

目的 评价在应用角膜共焦显微镜检查指导下的老年坏死性角膜基质炎(NSK)治疗效果.方法 51例(54只眼) NSK患者在角膜共焦显微镜检查指导下,根据角膜细胞结构的病变特点,局部应用更昔洛韦眼凝胶、环孢素A滴眼液滴眼,溃疡好转后联合低浓度皮质类固醇滴眼液滴眼或单纯应用更昔洛韦眼凝胶联合低浓度皮质类固醇滴眼液治疗,随诊观察16～28个月.结果 老年NSK组(≥60岁)治愈率(84.62%,10 /13)与≤59岁组(80.48%,35/41)比较,无明显差异(P＞0.05),老年NSK组复发率(7.69%,1/13)与≤59岁组(4.88%,2/41)比较,差异亦无显著性(P＞0.05).结论 NSK患者治疗效果与年龄无关,在角膜共焦显微镜检查指导下选择合理用药是治疗关键.
