This is a prospective study from patients with APAC presenting at the Faculty of Medicine Siriraj Hospital, Bangkok, Thailand in 2005. At presentation, patients received immediate ACP with a 30-gauge needle. The IOP, best corrected visual acuity (BCVA), corneal edema grading, pupil size and symptoms were recorded at immediately, 15 and 30 minutes, and then 1, 24 and 48 hours after paracentesis. All affected eyes received antiglaucomatous medications 60 minutes after ACP and underwent peripheral iridotomy within 24 hours.
