Comparison of anterior chamber flare among different glaucoma surgeries

PURPOSE: To compare postsurgical anterior chamber flare (ACF) among conventional (trabeculectomy, LEC) and novel (EX-PRESS Shunt, EXP) filtration surgeries and microhook ab interno trabeculotomy (μLOT), a novel minimally invasive glaucoma surgery (MIGS). SUBJECTS AND METHODS: This retrospective stud...

Sumario:PURPOSE: To compare postsurgical anterior chamber flare (ACF) among conventional (trabeculectomy, LEC) and novel (EX-PRESS Shunt, EXP) filtration surgeries and microhook ab interno trabeculotomy (μLOT), a novel minimally invasive glaucoma surgery (MIGS). SUBJECTS AND METHODS: This retrospective study included 125 primary open angle glaucoma eyes (89 consecutive subjects) treated with μLOT (n=38), LEC (n=12), or EXP (n=75). The intraocular pressure (IOP), numbers of antiglaucoma medication, and ACF at preoperatively and 2 weeks; 1, 3, and 6 months postoperatively were compared among the surgical groups using a mixed-effects regression model. RESULTS: The postoperative IOP (p<0.0001) and medication use were significantly (p<0.0001) lower in the LEC and EXP groups than with μLOT for up to 6 months postoperatively. The ACF differed significantly (p=0.0004) among groups; the ACF was significantly higher (p=0.0097, post-hoc Student’s t-test) with μLOT (33.6±52.8 pc/msec) than the EXP (15.7±19.9 pc/msec) at 2 weeks and was significantly (p=0.0111, post-hoc t-test) lower with μLOT (7.9±2.0 pc/msec) than LEC (12.0±6.1 pc/msec) at 6 months. CONCLUSION: Considering our observation, although its clinical significance is unclear, not all MIGS are minimally invasive regarding early postsurgical inflammation.
