RESUMEN
Objective:To investigate the preventive efficacy of interferon α -2b on scar formation after glaucoma filtering opera-tion. Methods:Totally 62 patients with primary glaucoma(68 eyes)were randomly divided into the observation group(31 cases with 36 eyes)and the control group(31 cases with 32 eyes). The patients in the observation group were given wet compress with a piece of cotton infiltrated by interferonα-2b,while the control group was given wet compress with a piece of cotton infiltrated by mitomycin C. After 4-month postoperative follow-up,the type of filtering bleb,complications and the changes of intraocular pressure were compared between the two groups. Results:The observation group was mainly with type II bleb(58. 33%),while the control group was mainly with type I bleb(53. 13%),and there was significant difference in the filtering bleb type between the two groups(P0. 05). The percentage of visual invariableness or improvement in the observation group was significantly higher than that in the control group(P<0. 05),and the occurrence of complications after the operation in the observation group was significantly lower than that in the control group( P<0. 05). Conclusion:Interferon α-2b is an ideal drug for anti-scarring formation after glaucoma filtration surgery.
