The Effect of Phacoemulsification on Intraocular Pressure in Primary Angle Closure Glaucoma (PACG) Patients At Phanat Nikhom Hospital, Chonburi Province

BACKGROUND: Primary angle closure glaucoma (PACG) is one of a leading cause of blindness worldwide including Thailand. This problem impact to the overall health of people and health care system. Treatment guidelines of each stage is differenced. Therefore, factors that affect to treatment should be explored to plan for taking care patients in the future.

METHODS: A retrospective descriptive study was conducted in 121 patients with primary angle closure glaucoma who underwent phacoemulsification between October 1st 2017 and September 30th 2022. The preoperative and postoperative record form were used as the research instrument. Visual acuity, intraocular pressure, the number of glaucoma medications and ocular biometric parameters were collected.
