摘要

背景:目的:确定交联(CXL)治疗是否会改变无角膜瘢痕的角膜炎患者的角膜光学密度(COD)与年龄之间预先存在的关联。方法:在两组患者中监测角膜光学密度:(i) 角膜炎标准 CXL 治疗前后(用新月形刀片去除角膜上皮,n = 69 只眼睛);(ii) 年龄/性别匹配、无任何角膜炎迹象的病例(n = 24 只眼睛)。使用 Pentacam™ 软件提供的 0-100 灰度计对七个不同的 COD 标记进行量化。结果第一组(19 名女性和 50 名男性)的平均年龄(±sd,范围)为 24.2 岁(±7.2,11-44 岁),第二组(9 名女性和 15 名男性)的平均年龄为 24.7 岁(±7.6,17-45 岁)。角膜顶点和角膜深度的 COD(y,任意刻度单位)与年龄(x,以岁为单位)相关,第一组在术前为(y = 0.08x + 13.12,r s = 0.350,p=0.003),在术后 12 个月为(y = 0.08x + 15.15,r s = 0.295,p=0.014),II 组在开始时(y = 0.16x + 11.28,r s = 0.474,p=0.019)和 12 个月后(y = 0.24x + 8.63,r s = 0.600,p=0.002)。CXL 后 COD 的变化与术前值有显著相关性。结论:CXL 最初会打破原有的角膜屈光度与年龄之间的关系。这种关系在术后 12 个月时重新建立。CXL 引起的角膜屈光度变化取决于术前值,而与患者的年龄无关。

The Impact of Standard Cross-Linking on the Corneal Optical Density-Age Relationship in Keratoconus After Mechanical Stripping of the Epithelium.

Background: To determine if cross-linking (CXL) treatment modifies any pre-existing association between corneal optical density (COD) and age in keratoconus free of corneal scarring. Methods: COD was monitored in two groups (i) before and after standard CXL treatment for keratoconus (de-epithelization with a crescent blade, n = 69 eyes) and (ii) age/gender-matched cases without any signs of keratoconus (n = 24 eyes). Seven different markers of COD were quantified using a 0-100 grey scale, supplied with Pentacam™ software. Results: Mean age (±sd, range) in Group I (19 females and 50 males) was 24.2 years (±7.2, 11-44) and in Group II (9 females and 15 males), it was 24.7 years (±7.6, 17-45). COD over the apex and along the depth of the cornea (y, arbitrary scale units) was associated with age (x, in years) in Group I at preop (y = 0.08x + 13.12, r s  = 0.350 and p=0.003), at 12 months postop (y = 0.08x + 15.15, r s  = 0.295 and p=0.014) and in Group II, at the start (y = 0.16x + 11.28, r s  = 0.474 and p=0.019) and 12 months later (y = 0.24x + 8.63, r s  = 0.600 and p=0.002). The change in COD following CXL was significantly associated with the preop value. Conclusion: CXL initially breaks down the pre-existing relationship between COD and age. This is re-established by 12 months postop. The CXL induced change in COD depends on the preop value but not on the patient's age.
