Clinical observation of deep-layer sclerotica removal of trabeculectomy

Objective To evaluate the curative effects of trabeculectomy plus deep-layer sclerotica removal in glaucoma.Methods 36 patients with different type of glaucoma were treated with trabeculectomy plus deep-layer sclerotica removal(group A,46 eyes),among them 26 ones(32 eyes) were primary acute angle-closure glaucoma,6(10 eyes) primary open-angle glaucoma and 4(4 eyes) secondary glaucoma,and compared with 33 patients receiving traditional trabeculectomy in our hospital(group B,46 eyes).after operation,ocular tension,atria,col-bubble and vision were observed and followed up for 1 years. Results Post-operation ocular tension or :21 mmHg were 42 eyes(91.30%) in the group A and 28 ones(60.87%) in the group B;in the group A,atria of 44 eyes completely formed within 3-4 days after operation,2 ones formed shallow of anterior chamber(4.35%) and did atria after 7 day medication;in the group B,16 eyes developed different extent of shallow of anterior chamber(34.78%);44 eyes had functional col-bubble in the group A(95.65%) and 28 eyes did in the control group(60.87%);in the group A,visions of 28 eyes improved,16 didn't change and 2 decreased: in the group B.16 improved,23 didn't change and 7 decreased,differerence showed statistictional significance between the 2 groups. Conclusions Traditional trabeculectomy plus deep-layer sclerotica removal can decrease the development of post-operation shallow of anterior chamber and effects of controlling ocular tension is better.
