Introduction: To compare the patterns of visual field (VF) defects in primary angle-closure glaucoma (PACG) to control groups of eyes with high-tension glaucoma (HTG) and normal-tension glaucoma (NTG). Methods: Forty-eight eyes with PACG were enrolled, and control eyes with HTG and NTG matched for age, sex, and mean deviation (MD) of VF defect were selected. VF tests were performed using the 24-2 program of HFA. VF defects were classified into six patterns with the Ocular Hypertension Treatment Study classification system and were categorized into three stages (early, moderate, and advanced). Each hemifield was divided into five regions according to the Glaucoma Hemifield Test (GHT). The mean total deviation (TD) of each GHT region was calculated. Results: Compared with HTG and NTG groups, the partial arcuate VF defects were more common in the PACG group. In the PACG group, the nasal GHT region in the inferior hemifield had the worst mean TD (-8.48 ±8.62 dB), followed by the arcuate 1 (-7.81 ±7.91 dB), arcuate 2 (-7.46 ±7.43 dB), paracentral (-7.19 ±7.98 dB) and central (-5.14 ±6.24 dB) regions; the mean TD of the central region was significantly better than those for all other regions (all P
