Ⅱ、Ⅲ度酸碱烧伤对眼表的影响

Effect of the Ⅱ, Ⅲ degree acid/base burns on ocular surface

摘要

摘要:
目的探讨Ⅱ、Ⅲ度酸碱烧伤对眼表的影响。
方法收集Ⅱ、Ⅲ度酸碱烧伤并且能够回访的病人，分为酸烧伤组（20例31只眼）和碱烧伤组（22例30只眼），病人中单眼未烧伤眼21例作为正常组。收集各组的泪膜破裂时间（BUT）、SchirmerⅠ实验、角膜表面规则指数（SRI）、角膜表面不对称指数（SAI）、角膜表面散光值（cylinder, CYL）。
结果酸烧伤组和碱烧伤组的BUT均低于正常组（P < 0.01），酸烧伤组和碱烧伤组差异无统计学意义（P>0.05）。3组的Schirmer Ⅰ实验、SRI、SAI、CYL差异均无统计学意义（P>0.05）。
结论Ⅱ、Ⅲ度酸碱烧伤后不影响泪液的分泌，但影响泪膜的稳定性。

Abstract:
ObjectiveTo investigate the effects of Ⅱ, Ⅲ degree acid/base burns on ocular surface.
MethodsThe patients with Ⅱ and Ⅲ degree acid/base burns were divided into the acid burn group(n=20, 31 eyes)and base burn group(n=22, 30 eyes), and 21 eyes without burn were set as the normal group.The tear-film break-up time(BUT), Schirmer Ⅰ test, surface regularity index(SRI), and surface symmetry index(SAI)and cylinder(CYL)of cornea were collected.
ResultsThe BUT in acid burn group and base burn group was significantly lower than that in normal group(P < 0.01), and the difference of BUT between the acid burn group and base burn group was not statistically significant(P>0.05).The differences of the Schirmer Ⅰ, SRI, SAI and CYL among three groups were not statistically significant(P>0.05).
ConclusionsThe Ⅱ, Ⅲ degree acid/base burns do not affect the tear's secretion, but affect the tear-film stability.
