This document presents the case of a 40-year-old male carpenter who presented with decreased vision in his left eye over the past 4 months. On examination, he was found to have chronic primary angle closure glaucoma in his left eye, with a shallow anterior chamber, mid-dilated pupil, posterior synechiae, and high intraocular pressure of 36 mmHg. He had been prescribed topical eye drops previously but his vision did not improve. The right eye was normal. He was advised to continue his eye drop medications and take acetazolamide tablets for a week, with plans for trabeculectomy surgery on the left eye.
