ABSTRACT

@#AIM: To investigate the clinical analysis of dry eye and tear film stability in pterygium patients after autologous conjunctival flap transplantation. <p>METHODS: Totally 114 cases of 138 eyes with pterygium were selected and divided into 56 groups of 67 eyes in the traditional group and 58 eyes of 71 eyes in the experimental group. The SⅠt values and BUT values of the two groups were observed before, 1 and 3mo after the operation, FL value, eye surface temperature and dry eye score of the two groups after surgery.<p>RESULTS: The total effective rate of the traditional group was 83.6%, and the total effective rate of the experimental group was 95.8%. The difference between the two groups was statistically significant(χ2=5.207, <i>P</i>=0.022); there was no difference in the SⅠt value before surgery between the two groups(<i>P</i>>0.05 ), SⅠt values in the experimental group increased significantly at 1, 3mo after surgery compared with the traditional group(both <i>P</i><0.05); there was no difference in BUT values before surgery in the traditional and experimental groups(<i>P</i>>0.05), and at 1 and 3mo after surgery the BUT value in the group was significantly increased compared with the traditional group(both <i>P</i><0.05); there was no difference in the FL score between the traditional group and the experimental group before surgery(<i>P</i>>0.05).FL value was decreased in the experimental group campared to the traditional group 1, 3mo after surgery(All <i>P</i><0.05); there was no difference in eye surface temperature between the traditional group and the experimental group(<i>P</i>>0.05), and the dry eye score test group was significantly lower than the traditional group(<i>P</i><0.05).<p>CONCLUSION: Autologous conjunctival flap transplantation is superior to simple tendon resection, which can promote the recovery of tear film stability in patients with pterygium, and the dry eye symptoms of patients are significantly improved.
