Combined trabeculectomy and injection of filtered air into anterior chamber in the treatment of primary chronic angle closure glaucoma
Abstract
AIM: To observe the clinical effect of compound trabeculectomy and air filtration injection in the anterior chamber in the treatment of chronic primary angle closure glaucoma, and to evaluate the safety and effectiveness of air filtration injection in the treatment of chronic primary chronic angle closure glaucoma.METHODS: In a retrospective study, 129 patients(183 eyes)with chronic primary chronic angle closure glaucoma admitted to our hospital from September 2015 to June 2017 were divided into air injection group and control group. Patients in the air injection group(68 cases, 97 eyes)were treated with compound trabeculectomy and air filtration injection into the anterior chamber. Patients in the control group(61 cases, 86 eyes)were treated with compound trabeculectomy. The follow-up time was from 3 to 6mo with an average of 4.5mo.The visual acuity, intraocular pressure, bleb formation and complications were observed, and the unplanned reoperation, length of stay and total cost of stay were recorded. RESULTS: The incidence of shallow anterior chamber, malignant glaucoma and unplanned reoperation in the air injection group was lower than that in the control group, the days of hospitalization in the air injection group were shorter than that in the control group, and the cost of hospitalization in the air injection group was lower than that in the control group(PFgroup=42.394, PgroupFtime=7.373, PtimeFtime×group=23.903, Ptime×groupP0.001)in intraocular pressure of 1, 3d and no significant difference(P>0.05)in 3, 7d between the two groups. There was no significant difference(P>0.05)in the flash of anterior chamber of 1, 3, 7d and 1mo between the two groups. There was no significant difference(P>0.05)in the changes of vision and the formation of filtering blebs between the two groups in 3mo(P>0.05).CONCLUSION:Combined trabeculectomy and air filtration in the anterior chamber for chronic primary angle closure glaucoma can reduce the incidence of shallow anterior chamber, malignant glaucoma and unplanned reoperation, not aggravate the inflammatory reaction in the anterior chamber, safely retain the residual visual function of patients, shorten the length of stay in hospital and the total cost of hospitalization, and have no effect on the formation of intraocular pressure, vision and filtering bleb obvious influence.
