Application of scleral adjustable sutures in surgery for angle closure glaucoma / 国际眼科杂志(Guoji Yanke Zazhi)

ABSTRACT

@#AIM: To explore the application value of scleral adjustable sutures in trabeculectomy and scleral biological amniotic membrane implantation for angle closure glaucoma. <p>METHODS: The clinical data of 94 patients(106 eyes)with angle closure glaucoma who underwent trabeculectomy and scleral biological amniotic membrane implantation were analyzed retrospectively. According to scleral adjustable suture used, the subjects were divided into the application group(study group, 54 patients 60 eyes)and the non-application group(control group, 40 patients 46 eyes). The occurrence of early shallow anterior chamber, continuous shallow anterior chamber and related complications in 2wk after surgery was observed and compared between the two groups. The formation of functional filtration bleb in 3mo after surgery was analyzed, and the improvement of intraocular pressure before surgery and 1mo after surgery was recorded.<p>RESULTS: In 2wk after surgery, the incidence rates of early shallow anterior chamber and continuous shallow anterior chamber in the study group were significantly lower than those in the control group(<i>P</i><0.05), while there were no significant differences in the incidence rates of complications between the two groups(<i>P</i>>0.05). One month after surgery, the intraocular pressure of the two groups were significantly lower than that before surgery(<i>P</i><0.05), and the difference of intraocular pressure before and after surgery in the study group was significantly higher than the control group. Three months after surgery, the formation rate of functional filtration bleb in the study group was significantly higher than that in the control group(<i>P</i><0.05). <p>CONCLUSION: The application of scleral adjustable sutures in trabeculectomy and scleral biological amniotic membrane implantation can effectively reduce the risk of shallow anterior chamber, which is of positive significance in improving intraocular pressure and formation of functional bleb in patients with angle closure glaucoma.
