ABSTRACT

AIM: To investigate the clinical features of dry eye with type 2 diabetic patients,and to analyze the correlation between the clinical features of dry eye and the disease condition.METHODS: Retrospective case series study.Dry eye cases with type 2 diabetic were analyzed from March to December in 2016.And the clinical features of patients were summarized.Dry eye examination including tear break-up time (BUT) and Schirmer test (schirmer Ⅰ test,SⅠt).Patients were divided into <60 years and≥60 years group by the age.And patients were divided into <5 group,5-9 years group,≥10 years according to the duration of diabetes.According to the condition of blood glucose,patients were divided into glucose controlled group and the group blood glucose uncontrolled.The results were statistically analyzed with gender,age,duration of diabetes and blood glucose level.RESULTS: There were 178 cases collected.All cases were diagnosed as dry eye both eyes.The patient`s age ranged from 32 to 85 years,with an average 58.41±13.06 years.There were 110 (61.8%) male cases,and 68 (38.2%) female cases.In all cases,the mean value of BUT was 4.52±2.31s,and the mean value of SⅠt was 4.25±1.99mm/5min.The value of women were more than men,but the differences were not significant statistically.Patients of ≥60 group were less than the age group of <60 patients,and the difference was significant statistically (t=4.153,4.021;P<0.01).In different course,all groups were lower than the normal.The value of≥10 years group was the least,<5 years group was the highest,and 5-9 years group was middle one.The differences were statistically significant (F=68.884,60.204;P<0.01).The value of blood glucose controlled group was significantly higher than the group blood glucose uncontrolled,and the difference was statistically significant (t=-6.615,-5.918;P<0.01).CONCLUSION:There were two types dry eye in 2 diabetic patients the instability of tear-film and the reduction of tear secretion.The clinic features of dry eye were related to age,the course of the disease,and the level of blood glucose.
