Combined trabeculectomy to treat glaucoma without anchor suture under topical anesthesia

Objective To investigate the clinical effect of combined trabeculetomy without anchor suture to treat glaucoma. Methods 43 patiens (59 eyes) underwent combined trabeculectomy with out anchor suture under topical anesthesia in our hospital. Tobramycin dexamethasone and atropine eye drops were given at 2nd day after surgery routinely,and the adjustable sutures were taken out based on the depth of anterior chamber and intraocular pressure(IOP). Results Morphologic characteristics of postoperative filtrating bleb: the filtrating blebs were divided into 4 types based on Krofed's standards. Ⅰ type blebs were observed in 6 eyes( 10.2% ), Ⅱ type blebs in 50 eyes (84.75%), Ⅲ type blebs in 3 eyes(5.08% ) ,and no Ⅳ type bles after followed for 1 year. Status of postoperative anterior chamber: Shallow anterior chamber were observed in 6 eyes during 7 days after surgery, and grade Ⅰ in 5 eyes, grade Ⅱ in 1 eye. The depth of anterior chambers were recovered in 2 to 4 days after pressure dressing and pupil dilation by atropine eye drop. Statue of postoperative IOP:the IOP 7 days after operation was 816 mmHg in 51 eyes(86.55% ) ,16 -21 mmHg in 18 eyes(13.56%), more than 21 mmHg in 2 eyes(3.39%). Conclusion The combined trabeculectomy without anchor suture under topical anesthesia can drop down IOP, form functional filtrating bleb and avoid postoperative complication in glaucoma patients effectively.
