AIM:To investigate the surgical treatment in filtering operation for malignant glaucoma with high intraocular pressure. Application of anterior chamber gas injection technology combined with adjustable suture can relieve ciliary blockand reduce the occurrence of malignant glaucoma.

METHODS:A total of 30 cases of closed-angle glaucoma patients with high intraocular pressure were selected as research objectives. Their intraocular pressure were >60mmHg at the first time. After detailed inspection those patients met the indications of compound trabeculectomy and were given drugs to reduce intraocular pressure with the preoperative intraocular pressure >45mmHg. The compound trabeculectomy were performed in those patients. After completion of the operation of scleral flap suture, it formed a state of intraocular hypertension with no anterior chamber(ciliary block). By suturing scleral flap with adjustable suture line and injecting sterile air into anterior chamber, anterior chamber was formed.

RESULTS: During the follow-up of 30 cases in six months, there were no malignant glaucoma; anterior chamber depth was stable; 25 cases of intraocular pressure were less than 18mmHg; 5 cases of IOP after follicular limitation were between 21-28mmHg.

CONCLUSION:If filtering surgery for closed-angle glaucoma is performed at a state of high intraocular pressure, the incidence of state of high intraocular pressure with no anterior chamber(ciliary block)state will be very high. By summarizing the 30 cases of this kind of surgery, this paper held that this method(suture of the scleral flap with adjustable suture combined with injection of sterile air in anterior chamber)can relieve ciliary block in the operation and avoid the occurrence of malignant glaucoma after this kind of operation.
