Ⅱ、Ⅲ度酸碱烧伤对眼表的影响

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

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SchirmerⅠ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。

Objective:To investigate the effects ofⅡ,Ⅲdegree acid/base burns on ocular surface.Methods:The patients withⅡandⅢdegree 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),SchirmerⅠtest,surface regularity index(SRI),and surface symmetry index(SAI)and cylinder(CYL)of cornea were collected.Results:The 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 SchirmerⅠ,SRI,SAI and CYL among three groups were not statistically significant(P>0.05).Conclusions:TheⅡ,Ⅲdegree acid/base burns do not affect the tear′s secretion,but affect the tear-film stability.
