Tears Of Patients With Lacrimal Punctum Form Of Clinical Research

Objective: Explore the relations between the shape of lacrimal punctum, gender, age and tearing through the clinical research on the shape of lacrimal punctum of the patient presented with tearing.Methods:Examine the patient presented with tearing by using slitlamp in the dark room. Take photos of the patients'lacrimal punctum with Nikon digital camera 7900, and then classify them. Hyperplastic tissue in the eight cases are cut and analyzed by HE staning and then the data collected are analyzed by SPSS11.5.Results:The shapes of inferior lacrimal punctum are generally divided into five types: volcanic crater, applanation, coarctation, polypus,mixed type. Of the 50 tearing cases, patients with coarctation type account for 34% and those with mixed type account for 14%. The proportion of the former is the largest while that of the latter is the smallest. The results show the affections are remarkable after hyperplastic tissues are cut and analyzed by HE staining. By contrasting gender with tearing, under the analysis of variance, the differences are not significant.(P>0.05).Therefore the proportion of male and female tearing makes no difference. The contrasts between different age groups show that the disease incidence in the group of age 20 to39 is higher than that in the group of age under 20; the disease incidence in the group of age 20 to 39 is higher than that in the group of age above 60; the disease incidence in the group of age 40 to 60 is higher than that in the group of age above 60.Conclusions: The shapes of inferior lacrimal punctum are generally divided into five types. There are certain relations between the shape of lacrimal punctum, age and tearing while gender is unrelated to tearing. Hyperplastic tissues together with normal tissues around them are remarkably different.
