PACG: primary angle closure glaucoma; PACS: primary angle closure suspect; AOD750: average of nasal and temporal angle opening distance at 750 μm from scleral spur; TISA750: average of nasal and temporal trabeculo-iris space area at 750 μm from scleral spur; ACA: average of nasal and temporal anterior chamber angle; ACD = anterior chamber depth; I-curve: average of nasal and temporal iris curvature; IT750: average of nasal and temporal iris thickness at 750 μm from scleral spur. Significant P values are demonstrated in bold.
