AIM: To discuss the operation manner and efficacy of traumatic angle recession glaucoma.<p>METHODS:The clinical data of 80 patients(80 eyes)who was treated traumatic angle recession glaucoma by three different operation manners between January 2008 and December 2013 retrospectively. Of them, 66 eyes of 66 patients whose onset time after injury was 1mo～2a, preoperative IOP was 25～<30mmHg, angle recession range ≤180°, optic C/D≥0.6 received trabeculectomy; 11 eyes of 11 patients whose onset time after injury was >2～10a, preoperative IOP was 30～39mmHg, angle recession range >180°, the disc C/D =0.6～<0.8 underwent compound trabeculectomy; 3 eyes of 3 patients whose onset time after injury was >10a, preoperative IOP 39～50mmHg, angle recession range >180°, the disc C/D =0.8～1.0 selected Ahmed glaucoma valve implantation. <p>RESULTS: IOP of all patients in three groups decreased to the normal range after operation(<i>t</i>=62.16, <i>P</i><0.01; <i>t</i>=20.39, <i>P</i><0.01; <i>t</i>=6.78, <i>P</i><0.01), without glaucoma symptoms and progressive visual field narrowing. Visual acuity in trabeculectomy and compound trabeculectomy groups increased slightly than that of preoperative, but it did no change significantly in Ahmed glaucoma valve implantation group. Sixty-five cases(98%)had effective filtering bleb in trabeculectomy group, 9 cases(82%)in compound trabeculectomy group and 3 cases in Ahmed glaucoma valve implantation group formed effectively bleb.<p>CONCLUSION: For those patients with ineffective drug treatment, we can choose a different surgical approach, according to onset time, angle recession range and IOP, to effectively reduce IOP, improve visual acuity, and avoid further damage to visual function.
