The clinical observation on trabeculostomy with deep sclerectomy

Objective:To evaluate the curative effect of trabeculostomy with deep sclerectomy (TDS)on primary close-angle glaucoma (PCAG).Methods:TDS was performed on 16 eyes of 16 patients.The procedure included laminating a half-thickness quadrangular or a triangular scleral flap,making two scleral strips in which Schlemm's canal was included and introducing strips into the anterior chamber angle.The visual acuity,anterior chamber depth,scleral strips inserted into the angle,intraocular pressure (IOP) and bleb were observed postoperatively.The mean follow-up was 11.5 months.Results:11 eyes obtained higher visual acuity,and 5 eyes were maintained visual acuity at their pre-operative level.The strips inserted into the angle of anterior chamber were kept the angle patent.The IOP of 16 eyes had been maintained at less than 15.75 mmHg.7 months after operation,among which 2 eyes reached to 19.25 mmHg 8 months after operation and then remained the same.The functioning filtering blebs were formed in all eyes,flat chamber in 4 eyes and choroidal detachment in one eye which became normal by treating with steroid eyedrop,Diamox and firmly taped eye pad.Conclusion:Trabeculostomy with deep sclerectomy is a safe,reliable and effective surgical therapy for primary close-angle glaucoma.
