The treatment of the chamber angle separation technique and pupil angioplasty combined phacoemulsification and intraocular lens implantation on acute angle-closure glaucoma with mydriasis and cataract

Objective To observe the effect of the treatment on cataract and mydriasis after acute angle-closure glaucoma by chamber angle separation technique and pupil angioplasty combined phacoemulsification and intraocular lens implantation. Methods Fifty-eight cases patients (69 eyes), including 23 cases of male patients and 35 cases female patients with cataract and mydriasis after primary acute angle-closure glaucoma were treated by chamber angle separation technique and pupil angioplasty combined phacoemulsification and intraocular lens implantation in our hospital from January 2009 to December 2015. The patients were followed up for 6 to 12 months, an average of 8.5 months. Intraocular pressure (IOP), corrected vision, anterior chamber angle, chamber depth, the optic nerve fiber layer thickness and operative complications were observed in 1 day of preoperation and 1 day, 1 week, 1 month, 3 months, 6 months, 12 months of postoperation. Results IOP of patients treated by systemic and locl drag therapy were (33.16±5.28)mmHg (1mmHg=0.133kPa) averagely in 1 day of preoperation. IOP of patients in 1 day, 1 week, 1 month, 3 months, 6 months, 12 months of postoperation were (22.36±1.24)mmHg, (17.11±1.22)mmHg, (16.48±0.29)mmHg, (16.28±0.29)mmHg, (16.24±0.38)mmHg, (14.15±0.24)mmHg respectively. Postoperative IOP reduced significantly than the preoperative IOP, the difference was significant (t=-7.522, P <0.05). corrected vision in 1d, 1w, 1m, 3m, 6m, 12m of the postoperative were 0.17±0.08, 0.32±0.15, 0.35±0.15, 0.42±0.18, 0.45±0.09, 0.46±0.17 respectively and which were significantly reduced than the preoperative corrected vision of 0.13±0.07, the results were statistically significant (P <0.05). Anterior chamber angle chamber depth of postoperation significantly improved compared with the preoperative. The difference was statistically significant (t=-17.935, P <0.05). Conclusions Chamber angle separation technique and pupil angioplasty combined phacoemulsification and intraocular lens implantation can effectively control the intraocular pressure in these patients and improve vision, and has better postoperative recovery.
