Clinical observation of argon laser peripheral iridoplasty in the treatment of acute attack of acute angle closure glaucoma

Objective To analyze the therapeutic effect of argon laser peripheral iridoplasty in the treatment of acute attack of acute angle closure glaucoma. Methods 88 patients in the acute attack of acute angle closure glaucoma were randomly divided into control group and observation group, with 44 cases(44 eyes) in each group.Patients in the control group received conventional medical treatment, while patients in the observation group received argon laser peripheral iridoplasty. The changes in the number of corneal endothelial cells of the affected and contralateral eyes, visual acuity and intraocular pressure were compared between the two groups before and after the treatment.Results After 4 weeks of treatment, the observation group had a number of corneal endothelial cells of(2012.24±502.27) cells/mm² for the affected eye and(2752.37±580.27) cells/mm² for the contralateral eye, while the control group had a number of corneal endothelial cells of(2285.46±535.55) cells/mm² for the affected eye and(2432.22±550.13) cells/mm² for the contralateral eye. Before the treatment, the differences in the number of corneal endothelial cells of the affected and contralateral eyes between the two groups were not statistically significant(P>0.05). After 4 weeks of treatment, the number of corneal endothelial cells of the affected of the observation group was lower than that of the control group, and the number of corneal endothelial cells of the contralateral eyes was higher than that of the control group, and the differences were statistically significant(P>0.05). After 4 weeks of treatment, the observation group had a visual acuity of(0.93±0.11)° and an intraocular pressure of(16.22±1.84) mm Hg(1 mm Hg = 0.133 kPa), while the control group had a visual acuity of(0.82±0.08) and an intraocular pressure of(23.36±2.14) mm Hg. Before the treatment, the differences in visual acuity and intraocular pressure between the two groups were not statistically significant(P>0.05). After 4 weeks of treatment, the visual acuity and the intraocular pressure of each group were better than those before the treatment, and the visual acuity and the intraocular pressure of the observation group were better than those of the control group, and the differences were statistically significant(P<0.05). Conclusion Argon laser peripheral iridoplasty has a certain effect on the corneal endothelial cells of the effected eyes in the treatment of acute attack of acute angle closure glaucoma. But it can improve the number of corneal endothelial cells in the contralateral eye, and adjust the visual acuity and the intraocular pressure in patients.
