Abstract:
?AlM: To observe the situations of different surgical methods on dry eyes in patients with pterygium excision combined transplantation.
?METHODS: Seventy-eight cases ofpterygium patients (81 eyes ) were randomly divided into three groups. Group A underwent pterygium excision combined large autologous conjunctival flap transplantation; group B underwent pterygium excision combined with small conjunctival flap;group C underwent pterygium excision combined with small conjunctival flap with autologous limbal stem cell. Repair of postoperative corneal epithelium, 1, 3mo preoperation and postoperation tear film break up time ( BUT ) and questionnaire of ocular surface disease index ( OSDl ) were observed among three groups, which caused the situation of dry eyes by pterygium and pterygium excision were evaluated.
?RESULTS: BUT: Group A was shorter than that in groups B and C at 15d postoperation (P<0. 05); at 1mo postoperation, group A was no statistical difference with groups B and C (P>0. 05). Postoperative dry eye ratio of group A was higher than that in groups B and C at 1mo postoperation ( P < 0. 05 ). There was no statistical difference between group B and group C ( P>0. 05 ) , but group C showed lower postoperative dry eye ratio. Corneal epithelium recover time of group A was longer than that in groups B and C (P<0. 05). There was no statistical difference between group B and group C ( P>0. 05), but group C showed a tendency to be shorter recover time.
? CONCLUSlON: Pterygium excision combined with small conjunctival flap and autologous limbal stem cell shows guickly corneal epithelium recover and low dry eye ratio and deserve to recommended.
