Efficacy Evaluation and Influencing Factors of Argon Laser Peripheral Iridoplasty in Acute Angle Closure Glaucoma

Second Affiliated Hospital, School of Medicine, Zhejiang University65 enrolled

Overview

To investigate the changes of angle structure and intraocular pressure after argon laser peripheral iridoplasty in patients with acute angle closure glaucoma patients whose intraocular pressure could not be controlled by drug therapy during the major attack period.

To evaluate intraocular pressure and anterior segment optical coherence tomography measurement parameters at baseline and each follow-up. Each patient was followed up for 6 weeks for 9 times. Visit 1st was baseline examination, visit 2nd was 1 hour after argon laser peripheral iridoplasty treatment, visit 3rd was 2 hours after argon laser peripheral iridoplasty treatment, visit 4th was 1 week after argon laser peripheral iridoplasty treatment, visit 5th was 2 week after argon laser peripheral iridoplasty treatment, and visit 6th was 1 month after argon laser peripheral iridoplasty treatment, visit 7th was 6 week after argon laser peripheral iridoplasty treatment.

Inclusion Criteria: * One eye had an acute attack, which could not be relieved by medication, and the intraocular pressure was more than 21mmhg; * The patients were 40 to 80 years old, regardless of gender; * Patients are able and willing to comply with the research guidance and may complete all visits required by the research; * Informed consent has been signed. Exclusion Criteria: * History of ocular trauma; * Any previous intraocular surgery; * Secondary glaucoma was diagnosed, including uveitis, neovascular glaucoma, glaucoma with elevated superior scleral venous pressure, lens dissolution glaucoma, glaucoma caused by lens dislocation, lens cortical glaucoma, pigmented glaucoma, etc; * The patient's history indicated that he had severe dysfunction of heart, lung, liver and kidney; * Women in pregnancy, lactation or planned pregnancy; * The researchers believe that the patient's condition may put the patient at a significant risk, may confuse the results of the study, or may significantly interfere with the patient's participation in the study.
