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.
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.
