The effect of paracentesis of anterior chamber on corneal endothelial cells in patients with acute attack of angle-closure glaucoma

Objective To observe the effect of intraocular pressure(IOP)fluctuations induced by paracentesis of anterior chamber on the corneal endothelial cell density(ECD)in patients with acute attack of angle-closure glaucoma.Methods The clinical data of 30 eyes of 30 patients of acute episodes of angle-closure glaucoma were analyzed from Nov.2018 to Nov.2019 in Tongji Hospital Affiliated to Tongji University were analyzed retrospectively.They were divided into two groups,15 cases underwent paracentesis of anterior chamber to control intraocular pressure as the paracentesis group,and 15 cases received IOP-lowering drugs as the drug group.Both groups received phacoemulsification and intraocular lens implantation combined with goniosynechialysis after IOP was reduced to normal.The best corrected visual acuity(BCVA),ECD,corneal thickness and complications were observed.The follow-up time was 3 months.Results At 3 months after surgery,the ECD in the puncture group was(1166.6±309.95)cells/mm^2,which was less than the(2034.7±261.23)cells/mm^2 in the drug group(t=-5.46,P<0.01).The difference of postoperative BCVA(t=3.21,P<0.05)and the corneal thickness(t=-4.01,P<0.05)were statistically significant.Conclusion The rapid fluctuation of IOP caused by repeated anterior chamber paracentesis may lead to the obvious loss of ECD during acute angle-closure glaucoma.
