We analysed the reduction of intraocular pressure (IOP) and topical glaucoma medication (Meds) in eyes following combined cataract surgery and SBG (Cat-SBG). Methods IOP and Meds were evaluated retrospectively in 55 eyes of 38 patients. 44 eyes had high tension glaucoma (HTG) and eleven eyes had normal tension glaucoma (NTG). Complete success (no Meds) and qualified success (with Meds) for IOP levels?≤?21,?≤?18?,?≤?16?mmHg or?≥?20% IOP reduction at the two- and six-month follow-up were evaluated. Results IOP and Meds were significantly reduced from before to two months after Cat-SBG in HTG- and NTG-patients (HTG: IOP 19.4?±?3.3 to 15.1?±?3.3?mmHg; p?<?0.001; Meds 2.1?±?1.3 to 0.8?±?1.3; p?<?0.001; NTG: IOP 14.0?±?2.3 to 11.5?±?2.3?mmHg; p?=?0.004; Meds 1.6?±?0.7 to 0.3?±?0.7; p?<?0.001). IOP and Meds did not change significantly from two to six months after Cat-SBG.In HTG, complete and qualified success rates were 43% (19/44) and 93% (41/44) for IOP?≤?18?mmHg, 36% (16/44) and 64% (28/44) for IOP?≤?16?mmHg and 30% (13/44) and 43% (19/44) for?≥?20% IOP reduction six months after surgery. In NTG, complete and qualified success was 81% (9/11) and 100% (11/11) for IOP?≤?18 and?≤?16?mmHg, and 27% (3/11) for IOP reduction?≥?20%.IOP and Meds reduction were comparable between HTG and NTG eyes.Only minor postoperative complications occurred.Conclusion Cat-SBG is an efficient method to significantly lower IOP in patients with HTG and NTG. 收起
